The intersection of aesthetic design and brand recognition has long been a battleground for international corporations seeking to protect their intellectual property within the rapidly evolving Chinese market landscape. In early 2026, the Supreme People’s Court of China issued a definitive judgment in a dispute between the global sportswear giant PUMA SE and a local entity, Kunshan Duowei Sports Goods, which fundamentally altered the legal framework governing design patents and prior trademark rights. This landmark decision marks a significant departure from previous judicial interpretations that often treated different forms of intellectual property as isolated silos rather than overlapping commercial protections. By prioritizing the market reality of how consumers perceive branding over technical visual differences, the court established a precedent that prevents the exploitation of the patent system to circumvent established trademark protections for footwear.
Judicial Evolution: Shifting Comparison Standards
Historically, the Chinese legal system utilized the “general consumer overall observation” standard to evaluate the validity of design patents, focusing primarily on whether the total appearance of a product was distinct from existing designs. Under this traditional approach, if a new design patent incorporated elements that looked similar to a famous trademark but surrounded them with enough secondary visual changes, the patent was often upheld as a unique creative work regardless of its potential to confuse the public. In the initial stages of the Puma dispute, lower courts and patent review boards adhered to this rigid visual-only rule, effectively ignoring the fact that the specific three-stripe motif used by the local firm was nearly identical to PUMA’s iconic branding. This created a legal loophole where bad-faith actors could register “new” designs that functioned as parasitic imitations of established global brands.
The Supreme People’s Court introduced a transformative standard that distinguishes between elements used for purely decorative purposes and those that serve as source identifiers in the minds of consumers. This new interpretation of Article 23 of the Patent Law clarifies that if a specific component of a design—such as a graphic pattern or a specific arrangement of stripes—functions as a trademark, its inclusion in a patent application constitutes “trademark use” that can be challenged. By acknowledging that a design can pass technical tests for novelty while still infringing upon prior trademark rights, the judiciary has provided a much-needed mechanism for clearing the market of confusingly similar products. This evolution ensures that the legal system no longer protects designs that are technically different yet commercially deceptive, forcing a more holistic analysis of how intellectual property interacts with consumer psychology.
Dual Functionality: Aesthetics and Brand Recognition
Modern industrial design frequently blurs the lines between aesthetics and branding, where the shape or pattern of a product serves both to attract the eye and to signal the manufacturer’s identity. The Puma ruling formally recognizes this dual functionality, asserting that when the aesthetic purpose of a design conflicts with the source-identifying function of a prior trademark, the integrity of the trademark must be preserved to protect the public interest. This legal hierarchy prevents companies from effectively owning a competitor’s brand identity through the clever application of design patents, which have historically been easier and faster to obtain than comprehensive trademark registrations. By establishing that the trademark’s role in identifying the source of goods takes priority in these conflicts, the court has reinforced the primary goal of intellectual property law to foster fair competition and prevent market deception in retail.
Beyond the immediate technical implications, the court’s decision serves as a powerful deterrent against the rise of entities that engage in predatory litigation tactics within the Chinese market. These entities have frequently registered slightly altered versions of famous international logos as design patents, subsequently suing the original brand owners or their distributors for infringement to extract lucrative settlements. The new standard makes it significantly easier for legitimate brand owners to invalidate these predatory patents by demonstrating that the designs are merely derivatives of their existing trademarked assets. This proactive stance by the judiciary protects the broader e-commerce landscape from the disruptive effects of serial lawsuits that capitalize on legal technicalities to hinder genuine commerce. It moves the Chinese patent system toward a model that rewards true innovation and creative industrial design rather than one weaponized for market harassment.
Market Integrity: Deterring Predatory Litigation
For global enterprises navigating the complexities of the current Chinese market, this judicial shift necessitates a fundamental reorganization of how intellectual property portfolios are managed and defended. The previous strategy of keeping design patent filings and trademark registrations in separate departments is no longer viable, as the validity of one now directly depends on the absence of conflict with the other. Businesses must adopt a cross-functional approach where design teams and legal counsel work in tandem to cross-reference every new product design against extensive trademark databases before filing for patent protection. This due diligence must extend beyond internal brand assets to include a thorough analysis of competitors’ visual identities to avoid accidental infringement or future invalidation claims. Companies that proactively audit their designs for potential trademark use conflicts will be better positioned to secure robust and enforceable rights.
The ruling also provides a more effective set of defensive tools for brands that find themselves targeted by infringing design patents or lawsuits initiated by local bad-faith actors. Legal teams can now leverage the “prior trademark rights” argument as a primary mechanism to cancel a competitor’s design patent, bypassing the need to rely solely on proving a lack of novelty or non-obviousness. This creates a more predictable and equitable legal environment, as international brand owners can rely on their long-standing trademark registrations to clear the path for their products without the fear of being blocked by parasitic patents. By bridging the gap between patent and trademark law, the Chinese legal system has provided a clearer roadmap for resolving complex disputes that involve overlapping rights. This maturation of the legal framework signals a commitment to aligning domestic standards with international best practices and protecting the creators of original brand assets.
Future Strategies: Integrated Compliance Protocols
The integration of judicial standards across different provinces is expected to harmonize the enforcement of these new rules, providing much-needed consistency for businesses operating across various regions. As local courts begin to implement the Supreme People’s Court’s guidance, the previous disparities in how design patents were treated are likely to diminish, reducing the risks associated with forum shopping. This harmonization is critical for maintaining a stable business environment where investment in unique product designs and brand development can be protected with a high degree of certainty. Companies that stay informed about these provincial updates and engage with local legal experts will be able to navigate the shifting landscape more effectively. Furthermore, the emphasis on market reality and consumer perception aligns the Chinese IP regime with the expectations of global stakeholders, fostering greater confidence in the legal system’s ability to resolve intricate design conflicts.
The resolution of the Puma case established a definitive boundary that restricted the misuse of design patents to infringe upon well-established trademark protections. Legal professionals recognized that the Supreme People’s Court prioritized the commercial reality of consumer confusion over narrow technical comparisons. This transition required companies to conduct exhaustive audits of their existing portfolios to identify vulnerabilities where design elements might have overlapped with third-party trademarks. Strategic planners implemented new protocols that integrated trademark searches into the early stages of the product design cycle to mitigate the risk of future litigation. Furthermore, the judiciary demonstrated a clear intent to sanitize the market of parasitic filings that had previously hampered legitimate business operations. Successful organizations responded by tightening their intellectual property strategies and ensuring that every visual identifier was backed by a comprehensive set of registrations across categories.
