On 29 June 2026, the Supreme People’s Procuratorate released five typical cases on the punishment of malicious intellectual property litigation, spanning utility model patents, design patents, trademarks, and unfair competition. The release reflects a balancing act China has been attempting for some time: tightening IP protection while keeping the legal system itself from being turned into a weapon by opportunistic litigants.
Beyond the individual case narratives, the release points to a broader governance problem. Certain actors have learned to use the appearance of IP rights, combined with civil procedure, as instruments of rent-seeking, competitive suppression, and procedural pressure. On paper, the claimant looks like a rights holder in good standing; in substance, the conduct departs from what IP law exists to do: reward innovation, protect goodwill, preserve the market’s identification function, and safeguard fair competition.
The Procuratorate found that some entities file IP lawsuits under the banner of rights protection while in substance chasing improper profits or engaging in unfair competition, conduct that harms other market participants, disrupts judicial order, and erodes judicial authority. The five cases operate on two levels: as corrections of specific erroneous judgments, and as signals of where China intends to draw the line between legitimate enforcement and abusive litigation.
I. A Governance Problem: Four Recurring Patterns
Across the five cases, four patterns of malicious litigation recur.
The first is patent litigation built on unstable or defective rights. In one case, a company filed a patent infringement suit claiming RMB 23 million just after a competitor’s listing application had been accepted, a claim large enough to trigger disclosure obligations and stall the listing process. On investigation, procuratorial organs found that the patent evaluation report had already concluded that every claim of the utility model patent failed to meet the conditions for patentability, and that the allegedly infringing products had in fact been manufactured before the patent application was even filed. The lawsuit was never really about winning. The filing itself was the instrument, capable of disrupting a listing timetable, unsettling investors, and loading the target with uncertainty regardless of the eventual verdict.
The second is concealment of a right’s invalidity. In another case, the right holder knew that its design patent had already been invalidated by the national IP authority, yet said nothing during litigation. The claimant went on to obtain several effective judgments and applied for their enforcement; only procuratorial intervention led to the judgments being revoked, the claims dismissed, and penalties imposed on the parties responsible. The case establishes a clear principle: litigation carries a duty of candour, and knowingly concealing a right’s invalidity is itself a form of malicious litigation.
The third is trademark squatting and hoarding turned into a monetisation strategy. Several cases involved entities that had registered or amassed large trademark portfolios with no genuine business behind them: no real use, no legitimate commercial intent. These entities then sued actual operators, prior users, and established businesses. The playbook follows a simple sequence: register, pressure, monetise. Formal rights are acquired cheaply; litigation, or the mere threat of it, is then used to extract compensation or settlements.
The fourth is the private capture of what amounts to public or semi-public commercial symbols, signs tied to urban tourism, local cultural heritage, or public commercial identity. Once such a sign is registered and turned against ordinary market participants, the dispute is no longer just an ordinary trademark case. It becomes a question of whether private rights are being used to fence off public resources, distort competition, and stunt the development of entire local industries.
Taken together, the cases mark a shift in what officials are worried about. The concern has moved from ordinary uncertainty at the boundaries of IP rights to the deliberate combination of formal rights, procedure, market timing, and commercial pressure. Malicious IP litigation, on this reading, is less a doctrinal puzzle than a form of procedural abuse embedded in market competition.
II. Instrumentalisation, Timing, and Rent-Seeking
Three features connect these patterns: the instrumentalisation of litigation, its strategic timing, and its use for rent-seeking.
Instrumentalisation comes first. Legitimate enforcement uses litigation to remedy infringement and protect innovation or goodwill. Malicious litigation converts the same procedure into a tool for imposing costs, manufacturing uncertainty, damaging reputation, disrupting financing, or simply pressuring a competitor into settling. The lawsuit’s value lies less in the eventual judgment than in the burden it creates the moment it is filed.
Timing is the second feature. Malicious claims cluster around critical commercial moments: listing applications, financing rounds, mergers and acquisitions, public tenders, product launches, brand relaunches, platform sales. At these moments, even a weak claim generates disproportionate pressure: it can trigger disclosure obligations, stall a transaction, unsettle a valuation, or create reputational damage well before any court has ruled. Timing itself becomes evidence of motive.
The third feature is rent-seeking dressed up as law. Cheap formal rights, such as patent filings, trademark registrations, and hoarded portfolios, manufacture the appearance of entitlement, which is then used to initiate or threaten litigation against genuine market actors. The right stops functioning as an innovation incentive and starts functioning as an extraction asset.
Doctrinally, these practices touch several principles at once: good faith, the prohibition on abuse of rights, the proper exercise of procedural rights, candour in litigation, and the protection of fair competition. The wrongfulness lies in knowingly wielding a defective, unstable, unused, or bad-faith-acquired right to generate improper pressure, regardless of whether the claimant ultimately loses the case.
III. From Formal Rights to Substantive Review
The typical cases’ main contribution is methodological: they show how malicious intent can actually be identified in practice. The core difficulty has always been that the claimant typically holds formal rights: a patent certificate, a trademark registration, notarised proof of purchase. Stop the analysis at formal entitlement, and abusive litigation becomes indistinguishable from ordinary enforcement.
The procuratorial approach moves beyond formal review toward something more substantive and contextual. Procuratorial organs now examine the stability of the asserted right, how it was obtained, whether it was genuinely used, whether infringement actually occurred, whether the parties compete with one another, whether the suit landed at a sensitive commercial moment, whether the claimed amount was proportionate, and whether the claimant has a pattern of repeat or batch litigation.
This matters institutionally on several counts. It stops registration or formal litigation status from counting as conclusive proof of legitimate rights exercise. It grounds findings of malicious intent in objective circumstances rather than subjective speculation. It lets procuratorial organs intervene during ongoing proceedings, by transferring leads and issuing supervisory recommendations, rather than only after judgments become final. And it reconnects IP litigation with the market context in which it actually operates.
The underlying shift, in short, is from formal legality to substantive legitimacy. The decisive question turns on whether the claimant’s overall conduct is compatible with what IP protection is for, and with the integrity of civil procedure, rather than on the mere production of a certificate.
IV. IP Protection Enters an Anti-Abuse Phase
For years, Chinese IP policy has been organised around a single imperative: protection that is stronger, faster, and more effective. That orientation has done real work: sharpening innovation incentives, improving the business environment, and meeting domestic and international expectations for stronger enforcement.
But stronger protection creates its own governance risk. As IP rights gain commercial, competitive, and capital-market value, they become correspondingly more attractive to opportunists. The stronger the protection attached to a formal right, the greater the leverage an abusive holder can bring to bear on a competitor.
The typical cases represent a recalibration of that policy. The goal is better-targeted protection, one that distinguishes genuine innovators and legitimate right holders from those who treat IP rights as instruments of procedural coercion.
High-quality IP protection needs both an enforcement arm and an anti-abuse arm. It must protect real innovation, genuine goodwill, and lawful market identification, while foreclosing patent trolling, trademark squatting, the hoarding of unused rights, profit-driven batch litigation, and unfair competition waged through litigation. Anti-abuse governance, on this view, is becoming an internal component of IP protection itself.
V. Implications for Companies
For companies, the practical effect will be a higher compliance bar for filing IP suits. Before bringing a patent or trademark claim, particularly against a competitor at a sensitive commercial moment, companies will need a more rigorous internal check on the validity of the right, the strength of the infringement evidence, actual use, the purpose of the litigation, the proportionality of the claim, and any competition-law exposure.
For high-tech firms, specialised and innovative enterprises, and companies preparing to list, the cases offer a measure of institutional protection. These companies are unusually exposed to strategic IP suits precisely because so much of their value sits in patents, technology, brand, and investor confidence. A weak but high-value claim filed at the right moment can disrupt financing, delay a listing, and distort valuation regardless of its ultimate merits; procuratorial supervision reduces that exposure by catching and correcting litigation that is abusive in substance.
For trademark agencies, IP operating companies, and entities engaged in batch enforcement, the warning is more direct. Large-scale registration without use, the absence of genuine business operations, and repeated suits against prior users or real operators may now count as evidence of bad faith in their own right. Trademark rights will increasingly be judged by use, commercial legitimacy, and effect on market order, alongside registration status.
More broadly, the cases should reshape litigation strategy across the IP ecosystem. Aggressive enforcement is no longer a free option: pursued on unstable rights, distorted facts, or improper competitive motives, it now carries legal risk of its own.
VI. Implications for Procuratorial Supervision
The cases also mark an expanding role for procuratorial organs in IP governance. Rather than simply correcting erroneous judgments after the fact, procuratorial organs identified abnormal litigation patterns, investigated the underlying facts, transferred leads, issued supervisory recommendations, lodged protests, and followed through on implementation.
Procuratorial supervision, in other words, is becoming a more active component of IP litigation governance. Beyond supervising legality, the procuratorate is emerging as an institutional actor capable of spotting procedural abuse, safeguarding judicial integrity, and protecting fair competition in its own right.
The governance structure taking shape is correspondingly multi-layered: courts adjudicate; procuratorial organs supervise legality and flag abnormal litigation; administrative IP authorities supply information on right validity and registration status; market regulation and competition-governance mechanisms assess the broader market effects. Together, these mechanisms point toward a more integrated system of IP abuse control.
VII. From Case Correction to Systemic Governance
The next stage of this governance effort is likely to move in several directions at once.
Identification standards will likely become more typological. Defective rights, concealment of invalidity, bad-faith trademark registration, non-use, batch litigation, disproportionate claims, and suits timed to critical commercial moments are all candidates to harden into recurring indicators in future cases.
Data-driven supervision should also grow in importance. Batch litigation, abnormal registration patterns, repeated claims by shell entities, and geographically concentrated lawsuits all leave traces in litigation data and administrative IP databases, traces that regulators and procuratorial organs can mine to detect systemic abuse far more efficiently than case-by-case review allows.
Corporate IP compliance will need to expand from acquisition to enforcement. Building a patent or trademark portfolio is no longer enough on its own; companies will also need to show that their enforcement actions rest on stable rights, solid evidence, genuine commercial interests, and procedurally honest conduct.
Finally, the links between IP litigation, capital markets, and innovation policy will become harder to ignore. Malicious suits against listed or pre-listing companies reach into disclosure, valuation, financing, and investor confidence. Anti-abuse supervision in IP litigation therefore touches judicial justice as well as capital-market stability and innovation policy.
Conclusion
The Supreme People’s Procuratorate’s release of these five cases marks a genuine refinement in China’s IP governance. The message is not subtle: IP protection does not mean unconditional support for every formal rights claim. High-quality protection requires a legal system that protects innovation while restraining its abuse, supports legitimate enforcement while rejecting procedural coercion, and safeguards private rights without sacrificing fair competition or judicial integrity.
Malicious IP litigation, in the end, sits at the intersection of IP law, civil procedure, market competition, capital-market regulation, and innovation policy, reaching well beyond any single instance of individual misconduct. By using procuratorial supervision to identify and correct abusive litigation, China is trying to keep IP law from being captured by speculative actors, and to hold intellectual property to its proper function: rewarding real innovation, protecting genuine goodwill, and supporting high-quality economic development.
