Challenging a Bad-Faith Trade Mark in China: Opposition, Invalidation and Cancellation

If a third party has registered, or is trying to register, a trade mark in China that copies your brand, you are not without options, but the route you take depends almost entirely on where that mark sits in its lifecycle. China operates a first-to-file system, which means rights generally go to whoever files first rather than whoever used the mark first. That structure, combined with a large volume of speculative filings, is why bad-faith registration has been such a persistent problem for foreign brand owners. The PRC Trademark Law and the China National Intellectual Property Administration (CNIPA) provide several distinct mechanisms to challenge a mark filed without genuine intent to use, or filed to trade off someone else's reputation. The difficulty is choosing the right one and assembling evidence that actually persuades an examiner or, on appeal, a court.

This guide walks through the three principal routes, opposition, invalidation and non-use cancellation, explains the bad-faith grounds that underpin them, and sets out the kinds of evidence that tend to help. It is written for brand owners and their in-house teams trying to understand their position before instructing a local agent. It is general information, not legal advice, and the procedural periods involved are version-specific and have been revised over time, so treat any timing point here as something to confirm with current official sources or a qualified Chinese trade mark agency rather than as a fixed rule.

How the three routes fit together

The first thing to understand is that the available remedy is governed by the status of the offending mark. There is no single "challenge a bad-faith mark" button; there is a sequence of windows, and you have to act within the one that applies.

Opposition is the pre-registration route. After CNIPA examines an application and decides to allow it, the mark is published for a period during which third parties can oppose. If you catch a bad-faith application during that publication window, opposition is usually the cleanest and least expensive path, because the mark has not yet matured into a registration.

Invalidation is the post-registration route. Once a mark is registered, opposition is no longer available, but you can apply to have the registration declared invalid on bad-faith and other grounds. Invalidation is the workhorse remedy for foreign brands who discover a squatted mark only after it has already registered, which is common.

Non-use cancellation is a different animal. It does not turn on bad faith at all. It allows anyone to apply to cancel a registered mark that has not been put to genuine use in commerce for a continuous statutory period. It is particularly useful against hoarders who register marks defensively or speculatively and never actually use them, because under current Chinese practice the registrant is generally required to come forward with evidence of use once a cancellation application is filed. That allocation of who has to prove what is a procedural point worth confirming with local counsel for your specific situation.

The table below is a rough orientation only. The exact periods, and the precise review and appeal tiers, are set by statute and implementing rules that have changed, so confirm the current position with counsel.

One nuance worth flagging: the precise review and appeal tiers are not uniform across these routes. Opposition outcomes and invalidation decisions follow somewhat different downstream paths through CNIPA's adjudication function and then the courts, and the exact ladder has shifted with successive reforms. Do not assume a single uniform "CNIPA then courts" sequence applies identically to each; confirm the current route for your action with local counsel.

In practice these routes are often combined. A brand owner who has missed the opposition window may file an invalidation action and, in parallel, a non-use cancellation, because the two attack the mark from different directions and a registrant who cannot prove use may struggle on both fronts.

Bad-faith grounds under the PRC Trademark Law

China has progressively strengthened its statutory tools against bad-faith filing, and reforms in recent years have placed real weight on the absence of genuine intent to use. The headline provision that practitioners point to is the rule against applications filed in bad faith that are not made for the purpose of use, which gives examiners a basis to refuse, and challengers a basis to oppose or invalidate, marks filed purely to squat, hoard or extract payment. This is the provision most often cited when the target is a large-scale hoarder rather than a single copycat filing.

Beyond that general bad-faith rule, several other grounds commonly do the work in real cases. There are provisions aimed at agents or representatives who register a principal's mark without authorisation, which is squarely relevant where a distributor, manufacturer or former partner has filed your brand. There are provisions protecting marks that have a certain reputation, including the well-known mark regime, which can in some cases reach across different classes of goods or services where a mark is genuinely famous, although this is discretionary and fact-specific rather than automatic. And there are prior-rights grounds, where the bad-faith filing conflicts with an earlier trade mark, trade name, copyright or other right you can establish.

It is worth being precise about well-known mark status in China. It is generally recognised on a case-by-case basis for the specific dispute in front of the authority, not granted as a permanent register entry or a standing "famous mark" badge you can rely on across future cases. Whether your mark qualifies, and how far any cross-class protection reaches, is a judgement that depends on the evidence in the particular matter, so treat it as a point to confirm with counsel rather than a fixed status.

Large-scale hoarding deserves a specific mention because CNIPA has become noticeably less tolerant of it. Where an applicant has filed an implausibly large number of marks, or has a pattern of filing other people's brands, that pattern itself becomes evidence of bad faith and of the absence of intent to use. Demonstrating that the registrant is a serial filer rather than a genuine trader is often more persuasive than arguing about any single mark in isolation.

The grounds you plead matter, because different grounds carry different requirements and, importantly, can carry different time limits for bringing an invalidation. Some grounds may be subject to a limitation period running from registration, while others may not. The way Chinese doctrine categorises these grounds, and which limitation period attaches to which, is technical and contested at the edges, so this is exactly the kind of version-specific point you should confirm with a local agent before relying on it. The answer can determine whether a route is still open to you.

Evidence that helps

Whichever route you choose, the outcome turns on evidence, and Chinese practice has its own expectations about what counts. Two broad categories matter: evidence of your own rights and reputation, and evidence of the other side's bad faith.

On your own side, the strongest position is an earlier Chinese registration or application, because the first-to-file system rewards filing. If you do not have one, you are relying on reputation and prior use, and you will need to show that your mark had become known, ideally to the relevant public in China, before the bad-faith application was filed. Useful material includes dated evidence of sales, marketing spend, media coverage, exhibition attendance, online presence directed at Chinese consumers, and any recognition or awards. Translated and properly dated documents carry far more weight than a general assertion of fame, and evidence that predates the offending filing is critical because anything after it is of limited value.

On the other side, you are building a picture of bad faith. The registrant's filing history is often decisive: a portfolio stuffed with other companies' brands, filings across unrelated classes, or marks that map suspiciously onto your product names all point away from genuine intent to use. Evidence of a prior relationship, such as a distribution agreement, supply contract, correspondence or shared exhibition history, supports the agent-or-representative ground and tends to be persuasive. So does any approach by the registrant offering to sell the mark back to you, which is close to a confession of the squatter's purpose. For non-use cancellation, the dynamic is different. Under current Chinese practice you generally make the application and identify the mark, after which the registrant is required to produce genuine, dated, in-commerce use of the mark in China; Chinese practice has tended to scrutinise token or contrived use more closely. That procedural allocation is China-specific and worth confirming with counsel.

Across all of this, presentation matters. CNIPA and the Chinese courts expect evidence that is dated, sourced, translated where necessary, and, for foreign documents, sometimes notarised and legalised. A local agency will know the current formal requirements, which is one of the practical reasons these actions are rarely run well from outside the country.

If you have not yet secured your own Chinese registration, doing so is often the single most useful defensive step, and our overview of how to register a trade mark in China covers the basics. For the wider problem of squatting, including prevention as well as cure, see our note on trade mark squatting in China. If you are filing internationally, the Madrid Protocol can be a route into China, though local strategy still matters once you are in the system. For the broader picture of protecting marks in China, our China trade marks overview sets the context.

Timing, discretion and realistic expectations

Two points temper any plan to challenge a Chinese mark. The first is timing. Opposition only exists during the publication window, invalidation only after registration, and some invalidation grounds may be time-barred after a period running from registration. Non-use cancellation only becomes available once the relevant continuous period of non-use has elapsed. These periods are set by statute and implementing regulations that have been amended, and further reform has been discussed, so the figures you find online may be out of date. Do not plan around a remembered number; confirm the current position with the office or a qualified agency before you rely on a deadline.

The second point is discretion. These are not mechanical outcomes. Whether a filing is found to be in bad faith, whether your reputation is sufficient, and whether claimed use is genuine are all judgement calls made by CNIPA and, on appeal, by the Chinese courts. Similar fact patterns can produce different results, and outcomes have shifted as policy has tightened against squatting and hoarding. A well-evidenced case improves your odds considerably, but no competent adviser can promise a result. Treat any prediction as a probability, not a certainty.

It is also worth weighing cost drivers rather than chasing a single tactic. The main drivers are official charges, which you should verify on CNIPA's official website rather than relying on third-party figures, plus local agency fees, translation, notarisation and legalisation, and the time the matter takes, which can be considerable where appeals are involved. Where a registrant is plainly a hoarder, combining invalidation with non-use cancellation can be efficient; where you have strong prior rights and reputation, leading with those grounds may be cleaner. The right mix is a judgement your Chinese counsel should make with the full file in front of them.

A brief word on getting advice

IPEnvoy is not a law firm and does not provide regulated legal advice. This guide is general information to help you understand the landscape before you act. Chinese trade mark procedure is technical, the procedural periods are version-specific and subject to reform, and the formal evidence requirements are strict. In practice, foreign parties pursuing opposition, invalidation or cancellation in China act through a registered Chinese trade mark agency, so any real challenge should be run with a qualified Chinese trade mark agency or law firm experienced in CNIPA opposition, invalidation and cancellation work. If it would help, IPEnvoy can connect you with vetted firms in China who handle this work, and who can confirm the current rules and deadlines that apply to your specific situation.
