Sometimes, and less often than the phrase suggests. A defensive filing is a mark you hold without using it, to keep a name or a class out of someone else’s hands. It works in crowded areas and near-famous names. It fails when it turns into filing fifteen classes you will never police, because an unused mark can be cancelled after three years.
Two different things get called defensive
The term covers two strategies that behave differently, and mixing them up is how budgets get spent badly.
| Kind | What you file | What it stops |
|---|---|---|
| Class coverage | Your existing mark, in classes you do not currently sell in, so a later filer cannot take your brand into packaging, accessories or services | A squatter registering your name in an adjacent class and using it to fence you in |
| Lookalike variants | Spellings, transliterations and near-identical versions of your mark, so the confusingly similar applications get cited at examination instead of being filed at all | Filings one letter away from yours, and Chinese-language variants of your name |
Both are real tools. Both cost money per class, and both run into the same wall, which is that a mark sitting on the register without use is a mark someone else can attack.
The rule that decides whether the money works
Under Article 49 of the Trademark Law, where a registered trademark has not been genuinely used for three consecutive years, any party may apply to cancel it. That applies to defensive filings like any other. A defensive mark is therefore not a permanent wall. It is a three-year instrument, renewable in effect only if you can show use when challenged.
What counts as use is broader than a sale, but it is not a formality you can backfill. Genuine use in China generally covers goods, packaging, containers, trade documents, advertising, exhibitions and licensing. The awkward case is export-only manufacturing, where use happens in China on goods that leave it, and where Chinese practice has been more accommodating than the phrase “no domestic sales” would suggest. We do not plan around that grey area. We plan for evidence: keep advertising, quotation material, booth photographs, invoices and packaging, dated, and the defensive mark has something to stand on when a cancellation request arrives.
Practical translation: a defensive filing you cannot evidence should be treated as covering roughly three years, and priced accordingly.
The arithmetic, honestly
Numbers make this decision easier than principles do, so here is the comparison using our published prices.
| Option | Cost | What it buys |
|---|---|---|
| One defensive class | US$199 official fee included | Your name held in one adjacent class for the next three years, longer if you can evidence use |
| Three defensive classes | US$597 | The adjacent goods class, the services class and one more you can justify, for example the packaging class your product is already packed in |
| Monitoring | US$399 per year | A watch on later filings in the classes you hold, which is what puts an opposition inside its three-month window |
| Opposing a filed application | Quoted case by case, then official fees | Removing a filing that has already been made, and already cost you something |
| Buying a registered mark back | Set by the seller | The register cleared, at a price that reflects how badly you want it |
Two conclusions follow. The first is that one defensive class costs half of one year of monitoring, and if you can only spend on one of the two, monitoring generally does more work, because it protects every class you hold rather than adding a class you do not use. The second is that a defensive filing is cheap relative to any of the clean-up routes. Where a class is genuinely crowded and your name is exposed, US$199 is not the expensive choice.
When a defensive filing earns its fee
- The class you make in is crowded. If a search shows several near-identical marks in your goods class, the adjacent classes are likely to be taken by the same kind of filer, and holding them yourself is cheaper than opposing later.
- Your name is a common word or a short English word. These get filed constantly across classes, and an early registration in the classes nearest your goods class is the cheapest citation you will ever own.
- Packaging puts your brand in another class. If your name appears on a box, a bag or an insert that sits outside your goods class, the brand is being used in two places. That is coverage, not defence, and it is usually the most defensible filing on this list.
- You are building a Chinese-language version of the brand. A Chinese name or transliteration that you intend to use is worth holding, and it is the version most likely to be filed by somebody else.
- You hold a trade name or a domain that others circle. Where the brand is valuable enough that lookalike filings are predictable, holding the nearest two or three variants is a way to make examination do the work for you.
When it is money you will not get back
- Filing the full Nice classification. Holding forty-five classes is not protection. It is an annual cost centre, a non-use exposure in each unused class, and it tells nobody that you are serious.
- Variants you will never police. Filing five spellings of a name you will never search against provides no defence, because the defence only operates when you notice a conflicting filing and act.
- A class you genuinely cannot use, with no evidence trail. If the mark covers goods you have never sold, advertised or shown, the three-year rule is a real deadline, not a theoretical one.
- Filing instead of fixing. If your goods list is wrong, if the applicant is the wrong entity, or if the class does not match the product, an extra defensive class does not repair any of it. We would rather see one clean registration than four confused ones.
How we usually structure it
Three layers, in order of what we spend on first. If the mark is the core of an export business rather than a fixture held against future filings, start with the export manufacturing guide instead.
- The classes you use. Non-negotiable, filed first, with goods lists built item by item. This is the foundation and nothing substitutes for it. How to pick them is in the classes guide.
- One or two adjacent classes with a real reason. Packaging, accessories, a storefront, a Chinese name you intend to use. One reason per class, written down, so the decision can be revisited next year.
- Monitoring for the rest. Rather than filing the classes you do not want, watch them. A published application that sits too close to your name is opposable, and opposition is a decision you take with full information instead of a fee you pay on a hunch.
Where a client wants the lookalike variant route, we run the search first and file the two or three variants that the search shows are actually being used by others. Filing variants that no one has ever approached is a fee without a purpose.
Worked example
| Situation | What we filed | Why |
|---|---|---|
| A skincare brand exporting from Guangdong. Search finds 11 near-identical marks in Class 3 | Class 3 in the brand’s own name, plus Class 5 for the adjacent medicated line it was already developing | The crowded class makes adjacency filings likely. The Class 5 line is real use, not defence |
| The brand also sells gift sets in a printed box | Added Class 16 for printed packaging | Coverage. The brand is genuinely used on the box |
| The brand considered Classes 35, 44 and 21 “to be safe” | Not filed. Monitoring added instead, US$399 per year | No storefront, no beauty services, no Class 21 goods. Three filings with no use behind them would have been three cancellation risks |
Total spend: three classes and a monitoring subscription, rather than six classes. The classes that were skipped are watched, so a filing there becomes a decision inside the opposition window rather than a discovery two years later. That is the trade, and it is usually the right one.
Quick answers
Does a defensive trademark have to be used?
Not to be registered. It has to be used if you want it to survive a non-use cancellation, which any party can request after three consecutive years without genuine use.
How much does a defensive filing cost?
The same as any other application: US$199 per class in Essential with the CNIPA official fee included, US$299 in Standard, US$499 in Registered or Refunded. Extra items beyond ten in a class are US$10 each. The full list is on the pricing page.
Are variants worth filing, or is that overkill?
Worth it when the search shows someone else using the variant. Overkill when it is a spelling nobody has approached in the years you have held the brand. The search answers this, and ours is free.
How many classes is enough?
As many as you have reasons for. In our files with exporters, that is usually two to four. The question to ask of each class is not whether it might be useful, but whether you would recognise a conflicting filing in it and act on it.
Can a defensive registration stop a copycat using my name?
It stops the registration, and it gives you a citation and a complaint basis. Stopping the goods is a different question, answered by enforcement and, at the border, by customs recordal.
What happens to a defensive mark if I never use it?
It stays on the register until someone files a non-use cancellation, usually from year four onwards. If the brand matters in that class, keep dated evidence of advertising, packaging or licensing so the answer is not just “we held it to block you”.

Ask which classes are actually worth holding
Send us your brand name, the product you make in China, and where else the name appears, on packaging, accessories, a Chinese-language version. We will search the register, tell you which classes are crowded, which neighbours are closest, and what we would file first. The search costs nothing, and we will say when a defensive class is not worth the money. Start with the registration service, see what the real cost looks like, and write to us for the search.
