Intellectual Property 2026

Introduction: Intellectual Property at a Turning Point

Intellectual property law is undergoing a period of profound transformation. Across the world’s major jurisdictions, courts and legislatures are confronting a set of converging pressures: the rapid rise of artificial intelligence, the borderless nature of digital commerce, and the surging economic value of intangible assets. From China’s evolving case law on AI-generated content to Japan’s landmark patent damages award, from South Korea’s punitive copyright reforms to Europe’s cross-border enforcement framework, the same fundamental questions are emerging everywhere: who owns creative output, where does infringement occur, and how should rights be valued? This guide maps the key developments shaping the new global IP landscape.

AI and the Reinvention of Intellectual Property

Every jurisdiction covered in this guide is grappling with AI in some form, although their approaches differ significantly.

China has gone furthest in developing a body of case law around AI-generated content. Early decisions suggested that sophisticated prompts might be enough to support claims of originality. More recent judgments have taken a stricter approach. Courts now require convincing evidence that a human exercised meaningful creative control over the output. Detailed generation records, evidence of iterative input, and proof of substantive human contribution have become increasingly important. The Chinese courts have also been active in defining the liability of generative AI platforms. Landmark decisions have distinguished between platforms that directly influence or control infringing outputs and those that merely fail to prevent them. These distinctions are beginning to shape expectations across the wider technology sector.

Elsewhere, the focus is different. Germany is wrestling with the practical implications of AI training and text and data mining. Courts and policymakers are examining how copyright holders can effectively reserve their rights and whether such reservations must be machine-readable in order to have legal effect.

South Korea has embraced AI both as a regulatory challenge and as a regulatory tool. AI-powered systems now assist with patent analysis and design searches, helping improve enforcement and examination processes. At the same time, authorities have tightened standards for AI-related inventions, reflecting concerns about maintaining patent quality in a rapidly developing field.

The End of Traditional Borders

Another striking theme is the growing strain on one of the oldest principles in IP law: territoriality.

Historically, legal rights were closely tied to geography. A patent granted in one country generally stopped at that country’s borders. Digital commerce has complicated that assumption. Online platforms, cloud infrastructure and international marketplaces make it increasingly difficult to determine where an allegedly infringing act actually occurs.

Japan’s Supreme Court, in Dwango v FC2, held that acts performed on overseas servers can constitute patent infringement if their effects manifest within Japan and the services are directed at the Japanese market – assessing the infringing act as a whole rather than mapping the location of each component.

South Korea has reached similar conclusions. In one notable case, a Chinese company marketed products through a foreign platform but used Korean-language descriptions, Korean-won pricing and Korean delivery options. The court held that these activities amounted to an offer directed at the Korean market, despite the infrastructure being located elsewhere.

China has also expanded its reach through legislative reform. Amendments to the Anti-Unfair Competition Law now expressly address conduct occurring outside China when it disrupts domestic market order.

Meanwhile, Europe is pursuing a different but equally significant solution. The Unified Patent Court is extending enforcement reach across multiple participating states through a single proceeding.

Although the legal reasoning differs, the direction is unmistakable: the assumption that server location defines legal exposure is not holding. Courts and legislatures are increasingly focusing on commercial impact rather than technical geography.

The Rising Value of IP Disputes

If there is one area where the importance of IP can be measured most clearly, it is damages.

For many years, patent litigation in Japan involved comparatively modest sums. That perception changed dramatically in 2025 when the Intellectual Property High Court awarded approximately JPY21.8 billion in a pharmaceutical dispute. The decision shattered a ceiling that had stood for more than two decades and immediately attracted international attention.

The case highlighted broader strengths of the Japanese system. Permanent injunctions remain relatively accessible, litigation costs are comparatively moderate, and proceedings are often faster than in many competing jurisdictions. Together, these factors have strengthened Japan’s position as an increasingly attractive venue for major patent disputes.

China’s experience tells a similar story. Punitive damages have become a more prominent feature of enforcement, with courts willing to impose substantial awards in cases involving deliberate infringement. This trend signals a broader willingness to treat IP rights as economically significant assets deserving meaningful protection.

South Korea has moved in the same direction. New rules permit punitive damages of up to five times the amount of loss for intentional copyright infringement, while criminal penalties have also been strengthened.

Germany traditionally places greater emphasis on injunctions than damages, but the Unified Patent Court has amplified the power of that approach. The possibility of obtaining relief across multiple countries through a single action can create enormous commercial pressure, particularly in technology-driven industries.

Standard Essential Patents

Few areas of IP law illustrate global divergence more clearly than standard essential patents (SEPs).

SEPs are patents that protect technologies required to comply with technical standards, such as those used in telecommunications. Because entire industries depend on access to these technologies, disputes often centre on whether patent owners are offering licences on fair, reasonable and non-discriminatory (FRAND) terms.

Japan offers a particularly interesting example of changing judicial attitudes. For more than a decade, successful SEP injunction claims were almost non-existent. That changed with the Tokyo District Court’s decision in Pantech v Google. What made the case remarkable was not simply the outcome but the reasoning behind it.

The court placed significant weight on the defendant’s refusal to engage with judicial settlement efforts. In other words, conduct during the dispute mattered as much as the underlying licensing negotiations themselves.

This emphasis has since been reinforced through Japan’s SEP litigation and mediation guidelines introduced in 2026. The new framework seeks to encourage global settlements under court supervision, with consequences for parties that refuse to participate constructively.

For multinational businesses, this creates a complex landscape. Different jurisdictions may apply distinct interpretations of FRAND obligations, creating opportunities for parallel litigation and strategic forum selection. Success increasingly depends on co-ordinating legal strategy across multiple countries rather than treating disputes as isolated national matters.

Conclusion

Despite their differences, the jurisdictions in this guide are responding to many of the same challenges: artificial intelligence, digital commerce, the growing value of intangible assets, and increasing international integration. Some countries have pursued rapid legislative reform, while others have relied on judicial developments or regional frameworks. Taken together, they reveal an IP landscape that is becoming more interconnected, more valuable, and increasingly central to economic growth and innovation.
