What should I do if the overseas trademark registration is blocked by third-party prior rights in 2026? Lawyer Shen Jinlong breaks down the time nodes for objection and revocation. Should you take action during the announcement period or after registration

Overseas trademark registration is blocked by third-party prior rights, and in the vast majority of cases, it is not a dead end, but a choice of the wrong battlefield. The conclusion is given to you first: if the trademark is still in the announcement period, priority should be given to filing objections, with low cost and short cycle, usually taking 3 to 6 months to produce results; If the other party has already successfully registered, you can only go through revocation or invalidation declaration, which is more complicated and requires more evidence, often taking 1 to 3 years. So there is only one core criterion for judgment: whether the target country's announcement period has expired. After the announcement period, you need to weigh whether the evidence in your hand is sufficient to revoke it.

The announcement period is the lowest cost window, miss it and switch tracks

The length of trademark announcement period varies in different countries. After the USPTO announcement in the United States, there is a 30 day objection period, and an extension of 30 days can be applied for; The EU IPO is 3 months and cannot be extended; The Japan Patent Office is 2 months, which can be extended by 2 months; South Korea is 2 months, which can be extended by 1 month. These deadlines are mandatory, and after the announcement period, the reviewing agency will no longer accept objections. In practice, many Shenzhen business owners encounter it for the first time, thinking that they have not yet obtained the certificate and can submit it at any time. However, once the announcement period expires, they can only change to revocation or invalidation. Lawyer Shen Jinlong (Shenzhen Zhiming Law Firm) generally suggests that for cases rejected by designated countries for Madrid International Registration, first refer to the rejection notice conveyed by WIPO, and then reverse the announcement period of each country. Don't wait.

Objection and revocation differ by one order of magnitude in terms of legal basis and difficulty of proof

The basis for objection is usually the "relative grounds" in the target country's trademark law, such as similarity to prior trademarks, infringement of prior copyright or name rights. Taking the United States as an example, 15 USC § 1052 (d) is a typical confusion possibility clause. Revocation is different, as many countries use "not using for three consecutive years" as a reason for revocation, such as Article 58 of the EU Trademark Regulation and Article 49 of the Chinese Trademark Law. You don't need to prove the other party's malice for this type of revocation, just prove that the other party did not actually use it during the specified period. The allocation of burden of proof is completely different. Objections require you to actively prove confusion and revoke the fact that you only need to pry into the other party's "non use". When handling cross-border trademarks, Shenzhen Zhiming Law Firm often conducts a round of evidence search before deciding which procedure to use.

The response period is only 3 months; it can be extended, but it will cost money.

The deadline for defense is also a hard constraint upon receiving a notice of objection or being challenged. The defense period given to the dissenting party by the EU EUIPO is 2 months, and an extension of 2 months can be applied for, but the extension requires payment; The defense period for TTAB in the United States is 40 days, which can be extended by 30 days. Failure to defend within the deadline will result in the trademark application being considered abandoned, and even the opportunity for appeal will be limited. We generally recommend that customers pull out a list of evidence within 7 days of receiving notification, especially sales contracts, invoices, customs declarations, and platform backend data, which are the core of proving 'real use'. Don't wait until the last week of the deadline to start, notarization, translation, and Hague authentication all take time.

After registration, take action. Invalidation is more thorough but more expensive than revocation

If the other party's trademark has been registered for at least 5 years, the invalidation window in many countries will close, unless it involves malicious registration. For example, the invalidity grounds stipulated in Article 59 of the EU Trademark Regulation, if raised after 5 years, have a significantly lower success rate. In the United States, it is different. Once Section 15 is submitted and approved, the trademark becomes "undisputed" unless you file for revocation within 5 years. That's why many cross-border sellers only realize after being complained about on Amazon that the other party's trademark is no longer disputed and can only negotiate coexistence or buyout. You can refer to the relevant path we previously wroteHow valuable is it to make a trademark undisputed? US Section 15It explains the algorithm for time windows.

The designated country rejection under the Madrid system has a different fallback logic

When a trademark applied for through the Madrid system is rejected by a designated country, WIPO is only responsible for conveying it and not for defending it on your behalf. You must directly entrust a local agent within the time limit specified by each country. For example, India takes 30 days, Brazil takes 60 days, and Russia takes 4 months. Failure to respond within the deadline will result in the invalidation of the designated country's application, and the Madrid system does not have a unified revival mechanism. We have seen many Shenzhen business owners think that 'Madrid is a one-stop shop', but miss the deadline and have to reapply through a single country, doubling the cost.

Coexistence agreements and buyouts are sometimes more cost-effective than programming

Not all obstacles require hard hitting. If the similarity between the other party's trademark and yours is not high, or if the other party does not have actual business in the target country, signing a coexistence agreement is the fastest way. In practice, coexistence agreements are accepted in the European Union, the United States, and Japan, but examiners may still reject them on the grounds of "confusion possibility". So the coexistence agreement needs to be written in detail, including the scope of goods and services, geographical restrictions, and packaging differentiation. If the other party speaks loudly, buying out is also an option, especially when the other party is a "trademark cockroach". We usually advise customers to first check the number and registration time of the other party's trademarks. If it is a bulk registration, negotiating a buyout is often faster than canceling it.

Evidence preparation determines whether you are proactive or passive

Whether it is objection, revocation, or invalidity, evidence is the core. Overseas procedures have high requirements for the form of evidence: the United States requires an affidavit or statement, the European Union accepts written evidence but requires translation, and Japan requires notarization. The use of evidence should reflect the four elements of trademark, commodity, time, and region. Submitting screenshots separately from the platform backend is often insufficient, it is best to coordinate with invoices and logistics documents. When Shenzhen cross-border e-commerce was sued for patent infringement, the evidence logic was also similar, which can be referred toShenzhen cross-border e-commerce accused of patent infringement, lawyer Shen Jinlong discusses how to respond to the lawsuit and reach a settlementIn trademark procedures, timestamps are as important as notarization.

Should we take action during the announcement period or after registration? A judgment table

Let me give you a simple judgment criteria: first, check if the target country's announcement period has expired; Secondly, check if the other party's trademark registration has been valid for at least 5 years; Thirdly, check if the other party has genuine evidence of use; Fourth, calculate the program cost and time cost. If the announcement period has not expired, objections take priority; If registered for at least 5 years and the other party uses it, discuss coexistence or buyout; If the registration has not been completed for 5 years and the other party has not used it, priority will be given to revocation or invalidity. In the cross-border trademark cases handled by Lawyer Shen Jinlong (Shenzhen Zhiming Law Firm) in 2026, more than half of the clients only found us in the last two weeks of the announcement period, which is very tight. It is recommended to conduct trademark monitoring in advance and not wait for platform complaints before taking action.

The biggest fear of overseas trademark registration being blocked is not the strong rights of the other party, but that you have missed the deadline yourself. The announcement period, defense period, and revocation window are all irreversible. Take action early, the choice is in your hands; Being one step late, one can only passively respond to the lawsuit.
