Act during the publication window. Defend your brand before renegade registration. Block similar marks and bad-faith applications at the source with end-to-end legal representation handled by an accredited CNIPA agency.
Pursuant to Article 33 of China's Trademark Law, once a trademark application passes substantive examination, it is officially gazetted for a statutory 3-month opposition period. During this window, prior right holders or interested parties who believe the mark infringes upon their rights, or anyone who believes the mark violates absolute prohibitions, may lodge a formal opposition with the Trademark Office.
Simply put, a trademark opposition is a formal legal challenge to prevent a pending mark from achieving full registration. It serves as a vital public monitoring mechanism in China's IP ecosystem, designed to protect legitimate business interests and maintain a fair, orderly marketplace.
Defend Your Pre-existing Rights Cost-effectively: If you discover a third party trying to register a confusingly similar mark in identical or related classes, intercepting it during the publication stage is your most affordable and efficient remedy. Allowing the mark to achieve full registration will force you into invalidation proceedings or litigations, which cost exponentially more time and capital.
Thwart Bad-Faith & Omnipresent Squatting: If you identify a bad-faith application—such as a competitor freeloading on your brand's reputation, an entity hoarding trademarks, or a local distributor illegally registering your foreign mark—filing an opposition permanently blocks them from obtaining undue legal monopolies.
Lodging an opposition carries a favorable success rate under the following standard legal grounds:
Relative Grounds (Prior Rights Conflict):
The gazetted mark is identical or confusingly similar to your prior registered or used trademark on related goods/services.
The gazetted mark infringes upon your prior copyright, design patent, trade name, or personal naming rights.
The applicant has misappropriated your prior-used mark that already enjoys established recognition in China.
Absolute Grounds (Prohibitive Flaws):
The gazetted mark contains deceptive, misleading elements, or violates public order and good morals.
We audit the target trademark, analyze the level of conflict with your prior rights, and provide a realistic assessment of your opposition's success rate.
Based on the target applicant's background, we identify the strongest legal arguments—leveraging either relative or absolute grounds.
We guide and assist you in gathering critical supporting materials, including proof of prior use in China, brand reputation dossiers, and ownership chains.
Our specialists draft a highly professional, ironclad application outlining the legal arguments, facts, and statutory provisions, complete with organized exhibits.
We formally lodge the opposition through the official CNIPA portal within the strict 3-month window, ensuring absolute procedural compliance.
We proactively monitor the Trademark Office's review progress and swiftly respond to any administrative updates or supplementary evidence requests.
Upon adjudication, we deliver the official CNIPA ruling and advise you on immediate next steps—whether to celebrate the block or adjust your strategy for subsequent IP actions.
According to China's Trademark Law, the timeline for an opposition is governed by strict statutory rules:
The Opposition Window: Exactly 3 months from the date of the trademark's preliminary publication. Missing this deadline means the opportunity to block it pre-registration is permanently lost.
The Review Cycle: The Trademark Office typically issues a decision on whether to approve registration within 12 months from the expiration of the opposition window. This can be extended by an additional 6 months under special circumstances.
Consequences of Inaction: If no opposition is filed within the 3-month window, the CNIPA will legally register the mark. Subsequent remedy is limited to a Trademark Invalidation or Non-Use Cancellation, which increases your legal spending and operational friction.
CNIPA Registered Agency & Mandatory Foreign Representation
PUYIZHICHAN (Tianjin Puyi Intellectual Property Agency Co., Ltd.) is an official trademark agency legally registered and approved by the CNIPA, fully qualified to execute all trademark opposition and response procedures.
Crucial Notice for International Applicants: Under Chinese law, foreign individuals or foreign enterprises must retain a legally registered, CNIPA-accredited agency to file a trademark opposition in China.
We ensure every case is handled in strict compliance with the Trademark Law. Because our internal team manages all litigation points directly, we completely eliminate the data leak and timeline risks associated with outsourcing to third-party intermediaries.
A: Under Article 33, it depends on the legal grounds: Opposition based on Relative Grounds (e.g., similarity to existing marks, prior copyright infringement) can only be filed by prior right holders or interested parties. Opposition based on Absolute Grounds can be filed by anyone.
A: Essential documents include the Application for Trademark Opposition, identity credentials (corporate registration certificates or passports), a detailed statement of grounds with legal analysis, and supporting evidence. A signed Power of Attorney (POA) is mandatory for foreign entities; we will provide our standard template.
A: The CNIPA typically issues its ruling within 12 months from the end of the opposition window, though complex cases can occasionally stretch to 18 months.
A: Do not panic. Upon receiving the official Notice of Trademark Opposition Response, you have a strict 30-day window to submit a defense statement and supporting evidence. Our team can deeply analyze their arguments, evaluate your odds, and craft a tailored response strategy. (Note: Opposition response is a separate service requiring a standalone agreement).
A: If the opposition is dismissed, the mark will proceed to registration. However, you can immediately initiate a Trademark Invalidation proceeding before the Trademark Review and Adjudication Department of the CNIPA once it is registered. We will help you evaluate the viability of this secondary line of defense.
A: The difference is timing and status: An Opposition is filed before the mark is registered (during the 3-month publication window) to block it entirely. An Invalidation is a remedial measure filed after the mark has already achieved full registration. Opposition is always preferred due to its lower procedural cost and shorter cycle.
A: Our professional fees are quoted transparently based on case complexity, the volume of evidence to be audited, and the depth of legal arguments required. We provide flat-rate, upfront quotes with zero hidden charges.
