Patent Infringement Actions
Generally, only patent proprietors and exclusive licensees have standing to sue for patent infringement. Nevertheless, others may also be granted the authority to assert certain claims under specific conditions and limitations.
Patent Proprietors
A patent proprietor, including a co-owner, has standing to sue for patent infringement. In this regard, depending on the particular claim of relief being requested, it is the formal registration as proprietor which is decisive, rather than the substantive ownership:
Co-owners may generally request a cease-and-desist order and the recall and destruction of infringing products on their own, ie, without the involvement of the other co-owner(s), unless stated otherwise in their agreement. With respect to damages, a co-owner must request the rendering of accounts and payment to all co-owners.
Exclusive licensees
An exclusive licensee also has standing to sue with respect to all available claims of relief, provided the infringing product and activity is within the scope of the licence.
It is not necessary to register the licence with the GPTO.
Others
Persons other than proprietors and exclusive licensees do not have their own standing to sue but may be empowered to assert certain claims by a proprietor or exclusive licensee.
Claims for damages and unjust enrichment are generally assignable and may, therefore, be asserted by an assignee.
Third parties with their own interest in stopping the infringer may seek injunctive relief and the recall and destruction of infringing products if the patent proprietor or exclusive licensee has authorised them to assert these claims on their behalf (Prozessstandschaft). Non-exclusive licensees typically have such an interest if the infringing activities affect their sales.
Joinders
In an infringement action brought by an exclusive licensee, involving the patent proprietor(s) is generally unnecessary since the infringement court cannot invalidate a patent.
There may, however, be other reasons for joining a third party in the litigation, and the German Code of Civil Procedure (GCCP) allows for such joinders.
Nullity Actions and Oppositions
In nullity proceedings, anyone has standing to sue, at least for as long as the patent is in force. The plaintiff must demonstrate a legal interest in the action if the patent has expired or lapsed.
The same applies to opposition proceedings before the European Patent Office (EPO) and the GPTO. However, the latter has little practical relevance in the field of life sciences. It is very rare, at least so far, to file an application for a German national patent for life science inventions.
Depending on the future experience with the Unified Patent Court (UPC), applicants may, however, wish to retain the possibility to litigate life science patents nationally by filing (also) nationally after the option to opt-out of newly filed European patent applications from the competence of the UPC has expired (probably in 2030).
German courts cast a wide net when it comes to patent infringers. Anyone who facilitates infringing activities in Germany, such as manufacturing, offering and putting the infringing product on the market, can be considered an infringer.
In the life sciences field, defendants are primarily the manufacturers or importers who hold the marketing authorisation. Wholesalers and others may be addressed in warning letters but are rarely joined as defendants.
A particularly interesting position in the German pharmaceutical market is held by a company called IFA GmbH. It is an information service provider for the pharmaceutical market. Specifically, it maintains a database of all pharmaceuticals distributed through pharmacies in Germany. The database, updated twice a month, is the basis (indirectly via providers of specialised software for pharmacies and other users) for all pharmacies' transactions with their customers and the pharmaceutical wholesalers who supply them. IFA is, therefore, a gatekeeper in the German pharmaceutical market. It regularly finds itself under pressure from (generic) manufacturers on the one hand and patent proprietors on the other, including as a defendant in provisional injunction proceedings.
Although main infringement proceedings in Germany are relatively fast by international standards (see below), provisional injunctions play an important role in life sciences litigation, especially in the case of a generic launch in the presence of pertinent patents (launch at risk). The reason for this is the immediate and irreversible impact of generic competition on the originator prices in Germany and other countries that refer to the price in Germany.
The provisional measures that can be requested are a cease-and-desist order and a seizure of infringing products.
Requirements for a Provisional Injunction
To obtain a provisional injunction, the petitioner must make it credible to the court that the patent is being infringed and that it would be unreasonable for the petitioner to be deferred to main proceedings. The latter is a comprehensive assessment including the patent's validity, urgency, and the parties' respective interests.
Infringement
In practice, there are no particular differences between the provisional injunction and main proceedings with respect to infringement. The court must be convinced that the patent has been infringed or that the infringement is imminent. The experienced patent panels, especially in Dusseldorf and Munich, are used to handling even technically complex cases if duly supported by the explanations in the petitioner's written submissions.
Validity
The standard for determining patent validity has been a topic of significant debate in recent years. Generally, most courts require that validity be confirmed beyond just the initial grant of the patent. This confirmation may come from the fact that the patent has withstood inter partes proceedings, such as an opposition, or has faced challenges from third-party observations during the prosecution phase. However, there have always been exceptions to this rule, especially in the context of early generic market entry. A panel of the Regional Court (Landgericht) Munich sought to challenge the prevailing practice by referring questions for a preliminary ruling to the Court of Justice of the European Union (CJEU). The CJEU ruled that the practice of rejecting provisional injunction requests when the patent's validity has not been confirmed in inter partes proceedings is contrary to EU law (judgement of April 28, 2022, C-44/21), and argued, inter alia, that European patents enjoy a presumption of validity upon grant. This judgement did not do much to resolve the differences. The Munich Regional Court sees it as confirmation of its more liberal approach. Other judges criticise that their practice was misrepresented to the CJEU, resulting in a decision not addressing actual practice.
Urgency
After becoming aware of the infringement and the infringer, the petitioner must promptly file their request for a provisional injunction without undue delay. A period of about four weeks is not considered an undue delay, but any significantly longer period requires a reasonable justification, such as the need for experiments, which must also be conducted expeditiously.
If, in the specific scenario, a confirmation of validity is required, a decision in inter partes proceedings, eg, by the Opposition Division, may start a new urgency clock.
Procedure
Requesting a provisional injunction to be granted ex parte
The petitioner may request that the provisional injunction be granted ex parte, ie, without hearing the respondent, but must justify that there is exceptional time pressure.
The court must consider this request in light of the respondent's constitutional right to procedural equality of arms. In principle, the respondent must be heard, but there are exceptions. Exceptions are, for example, cases of exceptional urgency or if the petitioner has sent a warning letter.
An ex parte injunction is often issued within one to two working days.
The court may also hear the respondent in writing before issuing a cease-and-desist order, which may take about two weeks.
Enforcing an ex parte injunction
The petitioner must execute the provisional injunction by serving it on the respondent.
The court may make the execution conditional on the respondent being provided security for their claim to be compensated for the harm incurred due to the enforcement of the provisional injunction, should the provisional injunction be lifted later. Such security is usually provided in the form of a bank guarantee from a German bank.
If the provisional injunction is not executed in the manner described above within one month of its issuance, the respondent may request that it be lifted on this ground alone. It will normally not be possible to apply for a new provisional injunction because of the lack of urgency.
Protective briefs
A protective brief is a common instrument to ensure that one is heard before the court considering an ex parte injunction. A protective brief is an anticipatory defence brief that is filed when one is concerned about an ex parte injunction, eg, before launching a product or attending a trade fair in Germany. The brief is filed with an online repository accessible only to the German courts.
Should a provisional injunction request be filed, the court would search the repository for a protective brief and decide how to proceed. A provisional injunction is still possible, namely when the protective brief fails to convince. If the court decides against issuing the provisional injunction, the court may contact the petitioner and recommend that they withdraw their request. If this is not done or the petitioner refuses, the court will proceed to inter partes proceedings (see e) below).
The protective briefs are valid for six months but can be renewed.
Objection by the respondent against an injunction order
If a respondent is faced with an injunction order, they can – at any time – file an objection with the court, which will cause the court to schedule a hearing, as set out below.
Oral hearing in provisional injunction proceedings
If the provisional injunction is not requested ex parte or if the court does not follow the request, the court will serve the provisional injunction request on the respondent and schedule an oral hearing, typically to be held about two to three months later.
The same applies if the respondent objects to a provisional injunction order.
The parties can make submissions up to the end of the oral hearing; there is no preclusion, and the other party must react, if necessary, on the spot unless the court finds that an assertion has been held back to blindside the other party. The hearing must, therefore, be prepared, taking into account all eventualities. Thus, potential witnesses and party experts should be present at the hearing.
Upon the hearing, the court would issue a judgment. Also, this judgment is merely provisional and can be challenged by the defendant at any time.
Relation to main proceedings
Provisional injunction proceedings are independent of a main action in Germany. Respondents can request the court to set a deadline for commencing a main action, but in practice, they rarely do so.
Patent infringement proceedings in Germany are bifurcated. The infringement courts are not permitted to hold that a patent is invalid.
Parallel invalidity proceedings must be pending to argue the patent's invalidity in the infringement action. These proceedings can have been initiated by the defendant or by a third party. They can be an opposition at the EPO or GPTO or a nullity action filed at the Federal Patent Court (Bundespatentgericht). Oppositions can only be filed within nine months after the grant. A nullity action is admissible when this opposition period ends, and no opposition is pending.
In the infringement proceedings, upon the main oral hearing, if:
the court may, in its discretion, order a stay of the infringement proceedings pending a decision in the parallel invalidity proceedings. In exercising this discretion, the court must balance the interest in non-contradictory decisions with the plaintiff's interest in a timely decision on infringement. Defendants should, therefore, not wait too long before commencing a nullity action.
First-instance Infringement Actions
An infringement action can be commenced at any time. As long as infringing activities are ongoing, the cease-and-desist claim will not be statute-barred. The claim can be considered waived, but not without the defendant taking steps that can be construed as a waiver. Claims for damages and unjustified enrichment can become barred by statute of limitation, even if infringements are ongoing.
To initiate an infringement action, the plaintiff must file a complaint with any of the regional courts (Landgericht) that have competence for patent matters and pay the court fee. German proceedings are front-loaded, so the complaint must substantiate the infringement and offer evidence.
The court will serve the complaint on the defendant. If service is outside the EU, it is served pursuant to the Hague Service Convention.
With the service, the court sets the defendant two deadlines, the first for an attorney-at-law to assume representation and the second for submitting the statement of defence.
After the initial exchange of complaint and statement of defence, the parties are free to exchange further briefs; one or two more rounds of briefs are typical.
While the burden of proof for infringement is initially on the plaintiff, if the plaintiff sufficiently substantiates their case, the defendant must dispute it at a matching level of substantiation. In this regard, the parties are prohibited to lie or mislead. It is, therefore, usually not sufficient for the defendant to merely dispute that the attacked embodiment is construed or operates according to the claim; the defendant must specify the allegedly non-infringing construction or operations. In this way, German courts largely manage without the need for document disclosure or discovery. A legal instrument to request disclosure of a specific document under certain conditions is available but rarely used. Discovery is not available.
The presiding judge can exercise more or less control over this stage of the proceedings, eg, by:
In patent infringement proceedings, all of those are rather uncommon as of late.
Eventually, the court will schedule the main hearing, usually about nine to 12 months after service.
If the court deems it necessary, it can call witnesses proposed by a party to be present at the hearing for questioning, predominantly by the court. This is, however, also rare in patent infringement proceedings.
To prepare for the hearing, the reporting judge writes a preliminary opinion based on the written submissions. This opinion is then discussed internally with the presiding judge and the third judge, resulting in the court's preliminary opinion. At the outset of the hearing, the presiding judge presents this preliminary opinion to the parties involved. The attorneys then have an opportunity to respond to the court's preliminary opinion. The entire hearing typically lasts about two to three hours.
Upon the hearing, unless the court finds that their decision hinges on a factual issue on which evidence must be taken, the court will issue a judgment within typically four to six weeks. If the decision favours the plaintiff, the plaintiff can provisionally enforce the judgment upon providing security.
First-instance Nullity Actions
As with infringement actions, the plaintiff initiates the action by filing a complaint with the Federal Patent Court (Bundespatentgericht) and paying the court fee. The complaint must set out all validity attacks in sufficient detail for the court to decide on this basis alone, should the defendant not dispute it.
A nullity action can be served on either the proprietor or the representative, as recorded in the GPTO patent register.
With service, the court will set the defendant a one-month deadline to declare whether they intend to object to the request for invalidation and a deadline of a further month (extendable to two months if sufficient grounds are given) to substantiate the grounds for the objection.
Within six months from service, the court shall issue a preliminary opinion.
The parties can exchange further briefs, and the court can set further deadlines to guide this process.
The main hearing is typically scheduled about 18 to 24 months after service, and a judgment is issued, usually about two months later.
Considering that the nullity action is usually prepared and filed as a reaction to being served an infringement action, ie, at least one or two months later, and the overall longer duration, the infringement court regularly decides on infringement, and a potential stay, before the nullity court has heard the case. The above-mentioned (early) preliminary opinion has been introduced to assist the infringement court in deciding whether to stay.
While an infringement action can be filed before a patent grant, a cease-and-desist order (in main or provisional injunction proceedings) requires that the mention of the grant has been published.
If a patent applicant wishes to stop infringements before the grant, an option may be to spin off a utility model from the pending application. A cease-and-desist order can be based on such a utility model after a few days or weeks, as only registration is required. Utility models are available for product claims, include medical use claims, and have a term of ten years (if spun off from a patent application, calculated from the application date of the patent).
The plaintiff bears the burden of proof regarding the infringement. In the case of a manufacturing process, this can be challenging. The German Patent Act (GPA), however, reverses the burden of proof if the patented manufacturing process creates a new product.
Under German law, there is no pre-action discovery or disclosure.
Inspection orders are available under Section 140c GPA. While the requirements in the books have been mostly aligned with procedures known in other European jurisdictions following the implementation of the EU Enforcement Directive 2004/48, inspection proceedings in Germany still have their own procedural particularities.
To obtain an inspection order, (i) the patentee or an authorised person is required to demonstrate that (ii) infringement is sufficiently likely, ie, that there are concrete indications for infringing acts by the defendant or another person, whereas (iii) the inspection into specific objects or documents assumed with the defendant (iv) is necessary for the applicant for establishing its claims. The court will then assess the proportionality of issuing such an order. In essence, an inspection order has the best chance of being granted if the applicant has collected all pieces for establishing infringement except for certain facts that are otherwise inaccessible to the applicant. Inspections can be sought in preliminary proceedings (Section 140c(3) GPA) and granted ex parte, provided that are is a sufficient reason (eg concerns that the purpose of the inspection may be frustrated if the defendant had advance knowledge of the request) and, according to some courts, urgent action of the applicant.
In order to ensure the confidentiality of the results while also fulfilling the proportionality requirement and permitting use of the obtained evidence in main proceedings, inspection requests are frequently combined with an evidence preservation procedure, as detailed in Section 485 of the Code of Civil Procedure. This process, known as the Düsseldorf procedure (Düsseldorfer Verfahren), involves a court-appointed expert conducting the inspection according to the tasks specified by the court. The applicant's outside counsel will accompany the expert and must adhere to a strict confidentiality order.
The process concludes with the expert providing a written report, after which the court will decide on the release of an unredacted version, having considered the parties' arguments. This final stage is generally completed within six months of the initial application.
Per Section 493 Code of Civil Procedure, the expert report may be utilised in subsequent infringement or unrelated proceedings (Section 411a Code of Civil Procedure).
Under German law, declaratory actions require the plaintiff to demonstrate a specific legal interest in the declaration being sought for the action to be admissible. Requests for declarations of non-infringement thus typically depend on a particular behaviour exhibited by the defendant, such as claiming entitlement to certain rights in a warning letter. A negative declaratory action is considered subsidiary to and thus does not bar a full action for performance.
“Arrow declarations”, ie, requests for a declaration stating that a specific embodiment is neither novel nor obvious in light of certain prior art (and thus cannot fall under the scope of protection of a patent granted later), have so far not been granted by a German court.
In contrast, infringement actions typically contain merely a declaratory request that the defendant is obliged to reimburse the plaintiff for any damage suffered from the infringement. As a result, German patent litigation typically consists of two phases: the first focuses on the infringement itself, while in the second phase the amount of damages may be subject to a separate action (see 5.4 Damages).
The claims of a patent define the scope of protection of a patent, and due account shall be taken of any element equivalent to an element specified in the claim (cf Protocol on the Interpretation of Article 69 EPC). Based on the understanding of the claims, the courts assess whether the skilled person could find the modified means used in the challenged embodiment to be equally effective for solving the problem underlying the invention, referring to three questions (cf FCJ, X ZR 168/00 – Schneidmesser I):
For striking a fair balance between the patentee's interest in covering equivalent solutions and legal certainty, the third question is of particular importance. Case law assesses each feature in the context of the description as a whole. A limitation of the claims to a particular example from the description may result in pledging alternatively disclosed embodiments to the public (FCJ, X ZR 16/09 – Okklusionsvorrichtung). Courts may turn to the patentee's submissions in the grant proceeding to assess whether an amendment was indeed meant to limit the subject matter of the patent, ie, to distinguish the claimed invention from the prior art, or merely to overcome formal objections (FCJ, X ZR 29/15 – Pemetrexed).
A court must not find equivalent infringement if the claimed solution was not novel or inventive over the relevant prior art (so-called Formstein defence, cf FCJ, X ZR 28/85). The rationale behind this defence is that the patent owner could not secure patent protection for an invention that was already in the public domain when filing the application. It follows that these known solutions or embodiments cannot constitute a patent infringement.
Under German law and practice, there is no obligation to clear the way before launching a product, and failing to do so is not a factor considered by the court when decision on whether to grant an injunction. However, a defendant must submit their validity challenge early – well before the oral hearing date in preliminary proceedings – if they want the infringement court to consider the likelihood of the patent being invalidated in its decision on an injunction.
Expert evidence plays only a limited role in German proceedings, as courts prefer to decide a dispute based on the parties’ written submissions. Questions of claim interpretation and validity of a patent are considered legal questions for the court to decide.
In infringement proceedings, parties often rely on statements and reports of private experts to verify and support the credibility of their assertions. Such evidence is, however, given no other procedural status than regular submissions by representatives unless the parties’ experts are proposed and summoned as witnesses. Party experts are not subject to particular duties and obligations to the court. Intentionally false statements and misleading the court can have consequences under general criminal law rules.
Upon request of the parties or its own assessment, a court may appoint a neutral expert as formal evidence for answering any specific factual question it considers relevant for deciding the dispute (Section 402 et seqq. Code of Civil Procedure). Court-appointed experts are required to maintain impartiality and to respond to the specific question posed by the court. Selecting experts, as well as preparing and discussing the expert report, typically in further oral proceedings, considerably delays a decision on the dispute. In preliminary proceedings, the court relies entirely on the parties’ submissions; court-appointed experts are not used.
Experiments are not treated differently than other forms of factual assertions. Parties may introduce the results of experiments into the proceedings in the form of written (expert) reports. The individuals who conducted the experiments may also be called to give witness evidence if disputed by the other side.
Further, court-appointed experts may be requested to conduct certain experiments to answer the questions referred to them.
As stated in 1.7 Pre-Action Discovery/Disclosure, there is no pre-action discovery or disclosure, and neither is there in the proceedings.
It is the plaintiff’s burden to substantiate and offer evidence for the facts underlying its legal claim. On the other hand, a party may utilise information from a variety of sources. Even information obtained illegally may, in principle, be used. In principle, even illegally obtained information may be used. Courts apply only limited exceptions, eg, if the manner in which the information was unlawfully obtained violated a person’s constitutionally protected fundamental rights. Moreover, the burden on the defendant to respond at a matching level of substantiation and not to lie and mislead in practice compensates for the lack of pre-action discovery or disclosure.
The GCCP allows a party to request the court to compel the opposing party to produce a specific document that is essential for the requesting party. However, this process requires a high degree of specificity, often proving unhelpful in practice.
Patent infringement proceedings typically evolve along diverging views on understanding the patent’s scope of protection. In addition, the defendant may rely on a number of defences:
Declaration of Willingness to Grant Licences
Section 139(1)3 GPA, in theory, also allows the defendant to rely on third-party (patient) interests for arguing that an injunction would have disproportionate effects but plays little role in practice due to a very high bar.
If the DoE is applicable, the Formstein defence may be invoked (see 1.10 Doctrine of Equivalents above)
Due to Germany’s bifurcated system, a defendant can only indirectly assert the invalidity of the patent concerned, namely by requesting a stay of the infringement proceedings in view of the success chances of a pending validity attack before the EPO or the federal courts (see below).
Stay Because of Parallel Invalidation Proceedings
As explained under 1.4 Structure of Main Proceedings on Infringement/Validity, the infringement court can stay the action in view of parallel German or EPO opposition proceedings or a German nullity action regarding the patent in suit.
Stay Because of Parallel CJEU Proceedings
Moreover, a court may also stay the infringement proceedings because of pending proceedings at the CJEU, eg, for a preliminary ruling, if the infringement court’s decision hinges on the outcome of the CJEU proceedings.
Stay Because of Lis Pendens
If proceedings involving the same cause of action between the same parties have been brought at another EU court, the German court must stay its proceedings according to Article 29 Brussels Regulation I (recast) until the court seized first has determined whether it has jurisdiction. If the proceedings are merely related, the court that has been seized later has discretion on whether to request a stay (Article 30 Brussels Regulation I (recast)).
No Discretionary Stay – Taking Foreign Judgements Into Consideration
The court, however, has no discretionary powers to stay the infringement proceedings, for example, to await a foreign decision in scenarios other than the one mentioned above. However, sometimes, a court’s use of its discretionary scheduling powers can appear as if it was done to await a certain event.
In principle, German courts must take decisions by a foreign court on another national part of the same European patent into consideration and, if the court comes to a different decision, explain why the court diverges. However, decisions from the USA or other overseas courts are not of much relevance since these courts’ practices are seen as being too different.
A patent can only be amended in opposition or nullity proceedings, not infringement proceedings.
In infringement proceedings, the plaintiff cannot amend the patent. However, a patent can be asserted in limited form (eg, to reduce the risk of a stay). This may also be done initially in the form of so-called “in particular” claims – that is, claims where the plaintiff substantiates that certain dependent claims or features from the description are also realised by the attacked embodiment – without limiting their broadest request for a cease-and-desist order. This allows the plaintiff to potentially limit the asserted claim later in the proceedings (ie, if the patent is upheld in such amended form).
The plaintiff may commence infringement proceedings or provisional injunction proceedings regarding a patent at any of the twelve regional courts with specialised patent panels, at least as long as infringing acts are conducted or imminent in the court’s territory. In practice, this gives the plaintiff freedom to forum-shop between these courts. As plaintiffs usually choose an experienced court, the Regional Courts Dusseldorf and Munich handle almost all infringement actions in the field of life sciences.
As set out under Requirements for a Provisional Injunction (Validity), above, these courts have developed a somewhat distinct practice related to the patent’s validity standard in provisional injunction proceedings, albeit it has no significant relevance in the early generic entry cases.
Under German law, different acts regarding a generic market entry can constitute a patent infringement, as outline below.
However, the following acts do not constitute a patent infringement:
The originator is responsible for submitting data regarding the initial market entry. The data will be protected for a period of eight years from the date of submission of this application for MA. During this period, the generic company is not permitted to access these documents.
Following the eight-year period, the originator is granted a two-year exclusivity period in the market. This indicates that a generic company is permitted to apply for an MA and may be granted such a status but must refrain from sales activity until the application is approved. The originator may request an extension of the market exclusivity period by one year if a new use is authorised within the first eight years and this new use provides additional value.
In total, the periods are described as “8+2+1”.
An exception is made for orphan drugs. Orphan drugs are granted a period of ten years of market exclusivity, which can be extended by a further two years.
The experimental use exemption under Section 11(2) GPA exempts any acts directed at gaining insights into the invention, including proof of function. Following the clinical trial decisions (FCJ, X ZR 99/92 and X ZR 68/94), such exempted experimental use may ultimately also be motivated by commercial interests.
In addition, the German legislator has opted for a broad implementation of the Bolar exemption in Section 11(2b) GPO, extending the exemption to all studies and tests and the resulting practical requirements undertaken to obtain a marketing authorisation, ie, not limited to generics and also applying to acts undertaken for obtaining non-EU, eg, FDA approval. It is the position of the German courts that third-party suppliers may also benefit from their customer’s exemption under the Bolar and experimental use exemption under strict requirements. A reform of the underlying EU legislation, which may provide for full harmonisation among the EU member states, is under discussion.
The Federal Institute for Drugs and Medical Devices publishes a monthly updated anonymised list of pending applications for marketing authorisations; granted MAs are compiled and publicly accessible in the AMIce database. No notice or other information will be given to the MA holder.
Marketed pharmaceuticals are included in the Lauer-Taxe, updated twice a month, with updates visible a few days before becoming effective.
MAs and reimbursements are granted without consideration of the patent status (no patent linkage system). The private company IFA is entrusted with issuing tag numbers for pharmaceuticals (PZN) and compiles the data on commercialised pharmaceuticals (which is then published, eg, in the Lauer-Taxe) and is at least partly acting as a gatekeeper against generic launch (see Germany Trends and Developments for details).
Public health insurers may, at least in theory, resort to indication-specific tendering as generic bidding on unlimited tenders may constitute an act of infringement if use patents still cover certain indications.
There are no differences between biosimilars and generics in terms of infringement (see 2.1 Infringing Acts above).
There are no differences between biosimilars and generics in terms of data and regulatory exclusivity (see 2.2 Regulatory Data and Market Exclusivity above).
The Bolar exemption under German law also covers biosimilars (see 2.3 Acceptable Pre-Launch Preparations above).
There are no differences between biosimilars and generics in terms of publicly available drug and patent information (see 2.4 Publicly Available Drug and Patent Information above).
There are no differences between biosimilars and generics in terms of reimbursement and pricing/linkage markets (see 2.5 Reimbursement and Pricing/Linkage Markets above).
In Germany, supplementary protection certificates (SPCs) are available for patents relating to active ingredients of medicinal products as well as plant protection products. The holder of a patent for a new medicinal product or plant protection product must refrain from placing it on the market until it has received the necessary authorisation. This reduces the period of effective protection of the patent. SPCs have been established to partly make up for this loss of exclusivity.
German SPCs for medicinal products are governed by Regulation (EC) No 469/2009, which has been translated into national law. Relevant provisions can be found in Section 16a and Section 49a GPA.
Any active ingredient or combination of active ingredients protected by a patent and subject matter prior to being placed on the market as a (human or veterinary) medicinal product may be the subject matter of an SPC.
Article 3 of Regulation 469/2009 sets out the requirements for obtaining an SPC for a medicinal product. The product (ie, the active ingredient or combination of active ingredients of the approved medicinal product) must be “protected” by a basic patent in force (Article 3(a)). There is no limitation to certain types of patents; a suitable basic patent may be a patent protecting the product, a process to obtain the product, or an application of the product. However, to be “protected” by the basic patent, the product must be “specifically identifiable” in the patent based on the disclosure of the patent, the common general knowledge and the prior art. Furthermore, the product must have received a valid authorisation to be placed on the market as a medicinal product for human or veterinary use (Article 3(b)). Each patent holder may only obtain a single SPC for a particular product (Article 3(c)) on the basis of the first authorisation for placing the product on the market (Article 3(d)). In other words, the holder of several patents must select one patent of the patent portfolio as the basic patent of the SPC. While it is possible to file several SPC applications, once an SPC is granted, it will prevent the granting of a further SPC to the same patent holder and the same product.
The SPC application must be filed in the name of the patent holder. It is often the case that the marketing authorisation holder and the patent holder are not identical. The current proposal for an amended SPC Regulation contains a provision according to which the patent holder may not obtain an SPC without the MA holder’s consent.
If the originator (the MA holder) and a third party both hold separate patents (and provided that both firms are unrelated entities), SPCs may be granted to both parties.
The circumstances under which an SPC for a combination of active ingredients can be obtained after an SPC for a single product has already been granted based on the same patent were the subject of the recent Court of Justice of the European Union (CJEU) decision on joined cases C-119/22 and C-149/22. At present, an SPC for the combination may be granted if there is a separate patent that specifically protects that combination.
Regulation (EU) No 2019/933 amends Regulation (EC) No 469/2009 and introduces the so-called manufacturing waiver for SPCs. This means that, despite the SPC, companies based in the EU can manufacture a generic or biosimilar product either solely for export to a country outside the EU (“third” country) where the product is not protected by a patent or SPC or during the last six months of the SPC term for placing it on the market in the EU once the SPC has expired (stockpiling).
The SPC term may be extended by 6 months if clinical studies of an agreed paediatric investigation plan (PIP) have been completed (see Article 13 No 3 of Regulation No 469/2009).
The paediatric extension of the SPC term was established as an incentive or reward for pharmaceutical companies for the investment and effort put into clinical studies testing the safety and efficacy of a medicinal product in the paediatric population.
Special MAs are possible for the paediatric use of a medicine that already has an MA for adults. These medicines must no longer be covered under a patent or an SPC and, furthermore, may not be developed specifically for children. As mentioned (see 4.2 Paediatric Extensions above), the paediatric use has to follow the PIP.
With a paediatric-use MA (PUMA), data protection is established for eight years and two subsequent years of market exclusivity. This topic is governed by Regulation (EC) No 1901/2006.
For the time being, an extension of the SPC term is not available for orphan drugs. However, an orphan drug has the advantage of a ten-year orphan exclusivity (see Article 8 of Regulation No 141/2000). This period can be extended by up to two additional years if clinical studies in accordance with an agreed PIP are completed. There are plans to reform the EU pharmaceutical legislation, which are likely to result in changes in the regulatory exclusivity periods.
Instead of a preliminary injunction in main proceedings, German law provides for a right to commence provisional injunction proceedings separately from main proceedings. We have addressed the relief available in those proceedings under 1.3 Preliminary Injunction Proceedings above.
A first-instance judgment in favour of the plaintiff may include an order to cease and desist from undertaking certain specified activities (final injunctive relief) as well as further claims of relief, such as the recall and destruction of infringing products.
The enforcement of a first-instance judgment that is not (yet) final requires the plaintiff to provide security (often in the form of a bank guarantee) for the defendant for the damages incurred due to the enforcement, should the judgment be set aside upon an appeal. The amount of security is within the court’s discretion but is usually set at the same level as the value in dispute on which the court fees and reimbursement claims are based (see 5.5 Legal Costs below).
To enforce the cease-and-desist order, the plaintiff must indicate to the defendant that the judgment is enforced by serving a copy of the judgment and the aforementioned security.
The defendant can petition the appeal court to stay the enforcement, but this is granted only in exceptional cases.
German law provides for an action for a compulsory licence, which can be filed with the Federal Patent Court. To prevail in this action, the applicant must demonstrate that:
A public interest exists in cases where the use right is required to provide a medicament for a serious illness that has either higher efficacy or fewer side effects than can be achieved with any other available medicament.
Besides this specific provision, a court must generally consider whether circumstances exist under which the injunction would lead to hardship for the infringer or third parties, which is disproportionate to the plaintiff’s interest in excluding those based on the intellectual property right granted to him. German courts apply this only in very exceptional cases, and in principle, it cannot replace the above action for a compulsory licence.
It is common practice in German infringement proceedings only to request a declaration that damages are to be compensated and that the defendant must render accounts. Upon obtaining the rendering of accounts, the plaintiff can commence a follow-on lawsuit, claiming payment of a specific amount of damages.
Those damages can be calculated under German law according to the methods of:
The plaintiff has discretion regarding the applied calculation method and can even apply different methods to different periods.
Damages are only meant to compensate for a loss suffered, not to penalise. In general, German courts are conservative regarding the amount of damages awarded.
It very rarely comes to a follow-on action on the amount of damages because the parties reach an out-of-court settlement once infringement has been established in a final decision or earlier because of a threatened or enforced injunctive relief. Therefore, the case law on the amount of damages is limited, so no industry-specific conclusion can be drawn.
In its decision, the court will also decide which party will bear the legal costs of the case or, if the costs are to be shared, which share of the costs. The legal costs include, in particular, the court fees (advanced by the plaintiff) and the attorney fees of the adversary. Both depend on the value of the dispute, which the court also determines on the basis of the parties’ submissions or the court’s own findings of facts.
In principle, the losing party pays the legal costs. However, a plaintiff must bear the legal costs of litigation if:
The plaintiff can avoid this risk by sending a warning letter, but it is necessary to decide on a case-by-case basis:
German courts have no discretion to reduce or withhold relief because of a plaintiff’s conduct unless the plaintiff holds a dominant position and if the conduct constitutes an abuse of that dominant position under competition law (Article 102 TFEU).
There are no special rules for trademarks relating to pharmaceuticals or life sciences, so any trademark must not be misleading or cause confusion with a pre-existing trademark.
In the life science field, trademark disputes are most common regarding repackaging pharmaceuticals for parallel import.
It is currently unknown if there are any copyright disputes in the life sciences and pharma sector in Germany.
Trade secret disputes are so far not very common in Germany in the pharma and life sciences sector.
Main infringement judgements and judgements in provisional injunction proceedings can be appealed at the higher regional courts. A further appeal at the Federal Court of Justice (FCJ) on a point of law is possible only in main infringement proceedings.
In nullity proceedings, the FCJ is the appeal instance so that the bifurcated tracks of the German system converge at the FCJ.
The higher regional courts and the FCJ also have specialised patent panels.
Patent infringement proceedings are subject to the same rules as any other civil procedure case.
Special provisions only apply to nullity proceedings.
The Unified Patent Court (UPC) has made a promising beginning, with cases from the life sciences and pharmaceuticals sector being presented at the UPC. However, national litigation continues to play a more significant role in this field, and this trend is likely to continue for the foreseeable future.
Mediation and other forms of alternative dispute resolution are available and may be suggested by the court under Section 278a GCCP, but they require the consent of both parties. The parties are also free to agree on any alternative approach to resolving their dispute, eg, through an expert determination. The parties may agree on such ADR once a dispute has arisen or in advance, as often is the case in IP contracts.
Objective statistics that provide a clear picture of the use of ADR to resolve disputes in life sciences are not available. Seemingly, ADR does play a role, either based on contractual dispute resolution clauses or agreed at the time of the dispute, but it is extremely rare compared to litigation.
The EU Commission, as the competent antitrust authority for the entire European Union, is closely monitoring the pharma and life sciences sector, both in terms of abuses of dominant positions and agreements that violate competition law. The EU Commission has been particularly critical of settlements that limit generic entry and include a value transfer to the generic company.
Group claims are only available regarding unfair practices against consumers. They can be brought by consumer advocacy organisations and are designed to assist consumers who have suffered minor damages and are unable to pursue their own legal action. They are not very relevant in the life sciences and pharma sector.

pm@hoffmanneitle.com www.hoffmanneitle.comThe German FCJ on a Reasonable Expectation of Success – Good Times for Patentees?
In the past decade, the concept of a reasonable expectation of success has gained considerable relevance for patent litigation in Germany. According to the established case law of the German Federal Court of Justice (FCJ), in assessing whether it would have been obvious from the prior art to solve a technical problem in a particular way, it may be relevant whether this would have been associated with a reasonable expectation of success, which is generally similar to the EPO’s Boards of Appeal case law. However, the FCJ’s specific approach is different from that of the EPO, as it is performed for each individual step on the skilled person’s path to the invention, rather than assessing the outcome, ie, the claimed invention directly (as at the EPO).
In 2023 and 2024, the FCJ further refined this case law. In particular, in its decisions X ZR 77/23 - “Testosterone ester”, FCJ X ZR 83/21 – “Sorafenib tosylate”, and “X ZR 92/23 - “Mirabegron”, the FCJ denied such a reasonable expectation of success and held that the claims were inventive. These decisions have already impacted German and UPC patent litigation practice, particularly in the field of pharmaceuticals and their medical uses.
The framework of the earlier FCJ case law
In its earlier case law, the FCJ had already established the basic criteria for assessing a reasonable expectation of success. According to these criteria, the courts shall determine, with due regard to the technical field in question, the extent of incentives for the skilled person, the effort required for adopting and pursuing a particular approach, and the alternatives in question, if applicable, as well as their respective advantages and disadvantages (eg, FCJ X ZR 59/17 - “Fulvestrant”, FCJ X ZR 24/19 - “Phytase”, FCJ X ZR 150/18 - “Pemetrexed II”, and FCJ X ZR 65/18 – “Tadalafil”).
After these criteria had been formulated by the FCJ in the Fulvestrant case, they initially proved to be a challenging hurdle for owners of some pharmaceutical formulation and dosing patents because the skilled person was seen to take a stepwise approach on their way from the prior art to the claimed invention. In other words, the reasonable expectation of success only needed to suffice for the next step rather than for the claimed subject matter as under the EPO’s problem-solution approach.
In the Fulvestrant case, the FCJ specifically asked whether the skilled person would have had a reasonable expectation of success in performing animal experiments as the first step to identifying the claimed pharmaceutical formulation. The FCJ held that a reasonable expectation of success, and hence obviousness, can already result from the skilled person’s incentive to test the efficacy and tolerability of a formulation in an animal experiment with sufficient predictive value for therapeutic use in humans. Thus, according to the FCJ, a claimed teaching may be obvious without requiring or even considering clinical tests.
In the Tadalafil case, the FCJ again asked whether the skilled person would have had a reasonable expectation of success to proceed stepwise, ie, to perform each individual step in pre-clinical and clinical development in order to arrive at the (surprisingly) low dosage of tadalafil. The outcome from the first step then provided an incentive to perform the further steps until the claimed subject matter was reached. The fact that the dosage was surprisingly low played no role, contrary to the EPO’s assessment. The FCJ considered that results of clinical trials in the prior art were not required for a reasonable expectation of success. Instead, mere in vitro data were considered sufficient to motivate the skilled person to conduct the next step in the development if there was a reasonable expectation of success only for such next step, and the outcome of this step triggered the remaining steps all the way to the claimed invention.
Recent developments and the testosterone ester case
Following the above decisions (that were unfavourable for owners of pharmaceutical dosing and formulation patents), the FCJ has now provided (counter-)examples of cases in which medical use or composition claims were found to be inventive.
In the Pemetrexed II case, which concerned a combination treatment involving pemetrexed, vitamin B12 and optionally folic acid, the FCJ held that there was no reasonable expectation of success in relation to using vitamin B12, inter alia because, firstly, it would have been necessary for the skilled person to deviate from the previous folic acid-based path of pre-clinical and clinical studies. Secondly, the skilled person would have had to return to an earlier development stage and perform studies for the claimed additional ingredient, vitamin B12, in animals and humans (see rec. 114-118). The FCJ was of the opinion that there was an imbalance between the incentive for deviating from the already promising path with only folic acid, on the one hand, and pursuing the additional effort required for the folic acid/vitamin B12 combination (that would have led to the claimed invention), on the other hand. As a result, the FCJ decided that there was no reasonable expectation of success, so the claimed combination was inventive.
The FCJ decision in the Testosterone ester case seems to expand further on this approach. The claims concerned a composition containing a testosterone ester and a vehicle comprising castor oil in a concentration of 25-45 vol.% and a co-solvent. There were hints in the prior art that the claimed concentration of castor oil would result in an advantageous property of the composition (lower viscosity). At the same time, there was a risk of losing the composition’s long-term depot effect. The FCJ considered that the expected advantage provided only a weak incentive for the skilled person and that a disproportionate amount of effort— including clinical studies requiring considerable time and financial resources — would have been needed to identify the effect on the required sustained release. The FCJ thus found that the claims involved an inventive step due to the lack of a reasonable expectation of success.
This seems to be generally in line with the Sorafenib tosylate case, where the FCJ acknowledged an inventive step for a specific salt of sorafenib (the tosylate salt) in an oral dosage form. The FCJ found sorafenib tosylate as such to be obvious in view of the prior art (disclosing sorafenib as an orally effective compound with anti-cancer activity) since the skilled person would have found and identified the usefulness of the tosylate salt in a routine “preformulation screen”. The FCJ determined that the salt was inventive when claimed in “an oral dosage form.” This conclusion stemmed from a specific problem related to the salt’s usefulness in this context: both the free base of sorafenib and the tosylate salt exhibited very low solubility. The FCJ thus concluded that the measures routinely employed in a pre-formulation screen would not have worked, and it had not been obvious or predictable that non-routine measures would have resulted in a better outcome. While the prior art was found to have justified an increased likelihood of success that there must be some form of sorafenib suitable for oral administration, this did not provide a sufficient guarantee that the tosylate salt would belong to “the group of the investigated substances” (the sorafenib forms to be tested for oral administration suitability). In other words, it was not “obvious to try” testing the suitability of the tosylate since there was no reasonable expectation of success to justify considering this compound as a possible candidate.
In the Mirabegron case, the FCJ acknowledged an inventive step for a second medical use of mirabegron in the treatment of overactive bladder. In the prior art, mirabegron had been known to be a selective β3-adrenoceptor agonist and had been suggested for use in, eg, preventing obesity and hyperglycaemia. It has also been known that an active ingredient having β3-adrenoceptor agonist properties can cause alleviation of the symptoms associated with an overactive bladder. The FCJ found the definition of the technical problem crucial, dismissing the lower court’s definition (“finding new fields of use or indications for mirabegron”) as containing elements of the solution. The FCJ confirmed its earlier case law (eg, FCJ X ZR 41/13 – “Quetiapin”) that the technical problem must be formulated in such a general and neutral manner that the question of what suggestions the skilled person obtained from the prior art in this respect only arises when assessing obviousness. Regardless of the starting point in the prior art (ie, on the one hand, the effect of β3-adrenoceptor agonists on overactive bladder symptoms or, on the other hand, the use of mirabegron for the treatment of other diseases), the FCJ saw the problem as “providing an effective remedy for the treatment of an overactive bladder”. The claimed solution was not obvious. The FCJ reasoned that while it may have seemed possible in the prior art that mirabegron could have the properties necessary for preventing and treating overactive bladder, there was no sufficient expectation of success in this regard, especially given the complexity shown in tests with other substances. Although many β3-adrenoceptor agonists were known in the art, this also could not establish a sufficient expectation of success, for it was known that not every one of these substances is equally suitable for the treatment of bladder dysfunctions and that a high β3-adrenoceptor selectivity was a necessary, but not a sufficient condition in this respect. The claimed second medical use was thus found to be non-obvious.
A patent-friendly trend?
While the recent FCJ case law seems promising for patent owners, this may not necessarily be a new trend in the sense of a departure from the previous case law. Rather, the FCJ has further supplemented its existing case law with individual cases in which applying the previously developed criteria has resulted in a finding of inventive step.
In particular, the FCJ’s reasoning in the Pemetrexed II, Testosterone ester and Mirabegron cases provides concrete examples of situations in which the balancing of the criteria for a reasonable expectation of success, including, eg, the incentives and the required effort, led to a favourable outcome for the patentees. Patent owners may look for similar arguments for their own cases. It may be helpful, for instance, to demonstrate that the skilled person needed to deviate from a previous path and/or that a considerable and unnecessary effort for the skilled person outweighs a small incentive.
Possible future interplay with the UPC
Historically, the concept of the reasonable expectation of success was introduced by some of the earlier decisions of the EPO’s Boards of Appeal, such as T 2/83 and T 149/93, and it was developed further by numerous further decisions of the EPO. The concept was eventually adopted by the German courts, albeit in a modified way, ie, not applying it to the claimed invention directly, but to the next step to be performed by the skilled person. If there are multiple steps on the path to the invention, each step is assessed in this way, using the outcome of the previous step as an incentive (in contrast to the EPO’s “problem-solution” approach).
Against this background, it will be interesting to see whether and how the case law of the German courts and the EPO, on a reasonable expectation of success, will influence the UPC and vice versa. While the UPC appears to have accepted this concept in principle, it has not (yet) defined a set of criteria for assessing a reasonable expectation of success.
In the Nanostring v 10x Genomics case (UPC CoA 335/2023) relating to provisional measures, the Court of Appeal (CoA) of the UPC held that “problems that regularly arise” in the technical field at issue would not have prevented a skilled person from carrying out the relevant tests (see p. 33). This approach of the CoA is consistent with the notion that – in accordance with EPO and German practice – certainty of success is not required.
Further, in the Sanofi v Amgen case (UPC 1/2023), the UPC Central Division (Section Munich) held that “The absence of a reasonable expectation of success (or more in general: non-obviousness) does not follow from the mere fact that other ways of solving the underlying problem are also suggested in the prior art” (headnote 4). Again, this notion is generally consistent with the case law of the EPO and the German courts, according to which the selection of one out of several obvious alternatives cannot establish an inventive step.
Accordingly, it appears that the UPC applies the concept of a reasonable expectation of success in a way that reflects a “common ground” of the approaches taken by the EPO and the German courts. Further cases will show whether the UPC’s approach is closer to the EPO or the German courts.
In this regard, it is interesting to note that, unlike the EPO, the UPC currently requires only a “realistic starting point” in the prior art but does not adhere to the concept of selecting a “closest prior art” document for the assessment of inventive step, suggesting that the UPC does not apply the EPO’s problem-solution approach strictly (see UPC 1/2023, headnote 3). This approach taken by the UPC resembles that of the German FCJ. The similarity between these courts’ views on inventive step may help to promote a further interplay between the case law of the UPC and the FCJ on inventive step in the future.
Divisional Applications in the Focus of Competition Law
Patent disputes, particularly major ones, often involve several members of the same patent family. EPO practice allows the applicant to branch off divisional applications as long as an application is pending (Article 76 EPC) and is traditionally little concerned with questions of double patenting, albeit in cases where the patent claims at issue cover the same, ie, identical, subject matter (c.f. EBoA, G 4/19). In consequence, unless literally identical, a patentee may file actions based on multiple patents covering almost the same subject matter against the same defendant.
The authorities have recently become more willing to intervene if they perceive a misuse of the option to obtain and rely on multiple patents of the same patent family protecting the same product. Following a dispute on patents covering the MS drug Copaxone (API glatiramer acetate), the European Commission (EC) issued a fine exceeding EUR460 million against Teva in October 2024 for abuse of its dominant market position (Article 102 TFEU). Teva was found to have created and enforced a “web of secondary patents” with similar content, which it strategically withdrew “to avoid a formal invalidity ruling, which would have set a precedent threatening other divisional patents to fall like dominos”. According to the EC, Teva thereby artificially prolonged legal uncertainty on the validity of its patents, potentially hindering the entry of competition (EC, Press Release re AT.40588). As early as 2020, the Regional Court of Munich issued a first-of-its-kind injunction, preventing the patentee from dropping a patent that had been enforced to prevent a (negative) decision on such patent’s validity (7 O 1456/20).
While the facts underlying the Copaxone investigation are specific and also involved commercial activities of Teva “disparaging” their competitors, which were not patent-related, the EC’s decision is of high relevance for the filing and enforcement strategies of patentees with a dominant position on their respective (pharma) market when relying on divisional applications and patents deriving therefrom with largely overlapping scope of protection.
IFA’s Responsibility for Listing Pharmaceutical Products in their Databases
In recent years, it has become common practice in Germany for patent holders to enforce patents not only against the pharmaceutical companies responsible for manufacturing, offering and launching an infringing generic product on the German market but also against IFA GmbH. IFA is an information service provider for the pharmaceutical market, collecting information from pharmaceutical companies and processing it into databases, which are essential for marketing pharmaceutical products in Germany. Among others, the Lauer-Taxe relies on information provided by IFA. For a long time, case law in Germany has established that the inclusion of an infringing product in the Lauer-Taxe qualifies as an infringing offer by the pharmaceutical company having applied for the product to be listed.
There have been numerous disputes, however, to what extent IFA can be held responsible for (contributing to) patent infringement by including infringing products in their databases. There has been case law holding IFA responsible for checking whether any products listed in their databases were infringing and preventing the inclusion of such infringing products in their databases when they had a reason for a corresponding check. IFA would be required to exclude an infringing product from their databases upon receipt of a corresponding provisional injunction against the supplier of the relevant drug or upon receipt of a notification by the patentee informing IFA about the (threat of) infringement. In many cases, the infringement would be obvious, for example, if there is compound patent protection and it is clear to IFA already from the active pharmaceutical ingredient that the attacked product falls within the scope of patent protection.
In Germany, there is no pre-warning of an infringing product launch, such as certain post-grant regulatory or other pre-launch steps which would have to be undertaken by a generic competitor prior to launch. As a clearing instance for pharmaceutical databases, IFA, therefore, plays a key role in the effective pre-emptive prevention of market disturbance by the offering and launching of an infringing generic product.
For patentees, it has thus been of particular interest to what specific remedies they are entitled against IFA in relation to (infringing) products which have not been published yet in the Lauer-Taxe, but for which IFA has obtained a request for inclusion in their databases. On the one hand, a (pre-emptive) provisional injunction against IFA can effectively prevent offer (and launch) of the infringing product from the outset. On the other hand, an obligation of IFA to inform the patentee about a request for having an infringing product listed in their databases would yield information useful for seeking a provisional injunction directly against the pharmaceutical company offering the infringing product.
Against this background, a provisional injunction of the Regional Court (RC) Munich I issued in March 2024 for Bayer against IFA in relation to the (prevention of the) listing of generic rivaroxaban products attracted a lot of interest. The RC held IFA responsible for checking whether infringement was obvious, stating that patent infringement should have been obvious for IFA even in relation to the case at hand where the infringement allegation was based on infringement by equivalent means. Most remarkably, the RC also ordered IFA to inform Bayer about any request for the listing of an infringing generic product.
However, as the Higher Regional Court (HRC) Munich was about to reverse the RC’s decision on IFA’s appeal, Bayer withdrew the request for a provisional injunction so that the RC’s decision lost its effect. In the introduction of the oral hearing in the appeal proceedings on 5 December 2024, the HRC took the preliminary view that patent infringement was not obvious and that the HRC would not concur with the RC’s position on the extent of IFA’s responsibility to examine and assess the patent situation.
As Bayer withdrew the request for a provisional injunction after hearing the HRC’s preliminary view, there is no written decision based on the court’s reasoning. It remains to be seen what position other German courts will take on the extent of IFA’s responsibilities, given that there is no recourse to the FCJ in provisional injunction proceedings and there may be deviating approaches taken by different Higher Regional Courts.
Liability under German Patent Law for Damages Incurred after Patent Expiry or Abroad
In two recent decisions, the FCJ developed the concept that a patentee is generally entitled to claim any damages resulting from patent infringement, even if the relevant damage occurs only after patent expiry or outside the territory of patent protection. While the underlying cases do not concern life science patents, the rationale behind the FCJ decisions can be highly relevant for calculating damages in cross-border life science patent disputes.
The general idea underlying the FCJ’s decisions is this: An act of infringement deprives the patentee of business opportunities associated with the patent. As a result, the patentee should be entitled to claim all profits resulting from the patent infringement, irrespective of where and when they materialize. It would be unfair if profits resulting from patent infringement would remain with the infringer.
In the first case decided by the FCJ in 2023 (FCJ X ZR 30/21 - “Upholstery conversion machine”), the infringer did not only sell the protected machine but also had agreements in place with their customers on maintenance and supply of use materials for the machine. The patent holder claimed damages not only for the sale of the protected machine but also for the additional services and supplies, irrespective of whether such services or supplies were conducted before or after patent expiry.
The FCJ stated that the patent owner might claim all infringer’s profits resulting from the infringing act (ie, sale of the protected product) unless (exceptionally) the attribution of the relevant profits to the infringement would be unjustified. Such an exception would only apply in rare cases, for example, if the infringer made additional profits by reinvesting the profits caused directly by the infringement.
Based on such reasoning, the FCJ ruled that the infringing sales of the machine caused both the sale of maintenance contracts and the sale of used materials. The market opportunities incorporated in the patent covering the machine also included the profits made by selling additional services. According to the FCJ, the damages claim for these additional services is not limited to the duration of the patent but rather includes the profits made with additional services after patent expiry as long as these sales were also caused by the infringing sale of machines during the duration of the patent.
In the second case decided by the FCJ in 2024 (FCJ X ZR 104/22 - “Evaporation dryer system”), an offer for the sale of a machine protected by a patent in force in Germany was made from Germany, while the subsequent sale of the machine took place in Sweden where the parallel patent had already expired. The patentee also claimed damages for the profits resulting from the sale in Sweden. The FCJ confirmed that the profits made by the sale in Sweden resulted from the infringing offer in Germany. The profits made in Sweden were associated with the market opportunity reserved for the patentee, who may, therefore, in principle, claim the infringer’s profits made in Sweden.
However, as only the offer took place in Germany, the patentee is only entitled to a fraction of the infringer’s profit, which can be attributed to the infringing offer. The FCJ sent the case back to the Higher Regional Court to assess the relevant facts of the case and determine the appropriate contribution factor, ie, to what extent it was relevant for the profit generation that the offer was conducted from Germany.
In patent disputes in the life sciences, there are numerous cases and constellations where certain acts of infringement or elements relevant for infringement are conducted in a country with patent protection and while a patent is in force (eg, manufacture and/or final batch release of an infringing product, or customization of a product for a patent-protected use), while subsequent activities resulting in significant commercial profits (eg, sales of the relevant product) are conducted in a country without patent protection or after patent expiry. The recent FCJ decisions strengthen the patentee’s position for claiming full damages resulting from patent infringement.
