Xiamen is part of the national patent system of the People’s Republic of China. Patent rights and substantive patent law are governed by the national Patent Law and implemented by the China National Intellectual Property Administration - CNIPA. Patent filings, examination and invalidation procedures follow national rules. Enforcement of patent rights in Xiamen occurs through local administrative authorities and the Chinese court system, including Xiamen people’s courts at basic and intermediate levels. For applicants and rights holders in Xiamen, the important practical points are that China operates a first-to-file system, recognizes three patent types - invention, utility model and design - and requires filings and procedural steps to be handled in Chinese by a registered patent agent when a foreign applicant is involved.
Patent issues can be technically and procedurally complex, and legal representation is often essential to protect your rights or defend against claims. Common situations when you should consult a lawyer include:
- Preparing and prosecuting patent applications - drafting claims and responses to office actions to maximize protection.
- Conducting prior-art searches and freedom-to-operate analyses before launching products.
- Handling PCT national-phase entry and priority claims for international filings.
- Responding to infringement threats or cease-and-desist letters.
- Filing infringement lawsuits or seeking administrative enforcement in Xiamen.
- Initiating or defending patent invalidation proceedings at CNIPA.
- Negotiating and drafting license, assignment or collaboration agreements involving patents.
- Managing cross-border enforcement, customs recordation for border seizures and evidence preservation.
- Conducting IP due diligence for investment, acquisition or partnership transactions.
Patent lawyers and registered patent agents provide technical drafting skills, knowledge of Chinese procedural rules, and experience with local courts and administrative bodies, all of which improve the chances of securing and enforcing patent rights effectively.
Key legal features and practical rules that affect patent matters in Xiamen are based on national law and local practice:
- Types of patents - Invention patents (20 years from filing), utility models (10 years) and designs (15 years). Invention patents undergo substantive examination; utility models and designs are subject to different examination standards and are generally faster to grant.
- Patentability criteria - Novelty, inventive step (inventiveness) and industrial applicability. China has strict novelty requirements under the first-to-file rule.
- Filing timelines - For PCT applicants, national-phase entry is normally within 30 months from the priority date. Domestic priority can be claimed under the Paris Convention. Time limits and procedural deadlines are strictly enforced.
- Prosecution and language - All prosecution documents before CNIPA must be in Chinese. Foreign applicants must appoint a China-registered patent agent or local counsel for prosecution.
- Invalidation - Once a patent is granted, third parties may file invalidation requests with CNIPA. Successful invalidation can be appealed to the people’s courts.
- Enforcement - Patent owners may pursue civil litigation in the people’s courts in Xiamen, seek administrative enforcement through local market supervision or IP administrative authorities for certain infringements, or request customs measures to block imports or exports of infringing goods. Courts may grant preliminary measures such as evidence preservation orders and injunctions in suitable cases.
- Remedies - Remedies can include injunctive relief, monetary damages, account of profits and destruction of infringing goods. Since recent amendments to national law, courts may award higher damages and, in serious willful infringement, punitive damages up to multiple times the actual loss in certain cases.
- Evidence and technical assessment - Chinese courts and administrative bodies often use technical appraisal agencies or expert determinations in patent disputes. Parties should prepare technical evidence and expert reports early.
- Local practice considerations - Xiamen courts may encourage mediation or settlement in IP disputes, and local administrative bodies may offer quicker, lower-cost remedies for straightforward cases. For complicated patent litigation or high-value disputes, civil court actions are often preferred.
You file a patent application through CNIPA. Applicants in Xiamen follow the national filing procedures. If you are a foreign applicant you must appoint a China-registered patent agent or local counsel to handle filings and prosecution in Chinese. For inventions you can file directly with CNIPA or enter the national phase from a PCT application.
China recognizes invention patents, utility model patents and design patents. Invention patents protect novel technical solutions and require substantive examination. Utility models are for structural or shape innovations and usually grant faster but offer shorter protection. Designs protect the appearance of a product. Choice depends on technical subject, novelty, enforcement strategy and desired term of protection.
Timelines vary: invention patents typically take several years from filing to grant under substantive examination; utility models and design patents often take 6-18 months. PCT national phase entry adds timing considerations. Timelines depend on workload, examiner queries and whether expedited examination is requested and available.
Yes, foreign entities can file patents in China. Foreign applicants must appoint a China-registered patent agent or lawyer to represent them before CNIPA for prosecution and communications in Chinese. Local counsel is also strongly recommended for enforcement and litigation in China.
First, gather and preserve evidence of infringement - product samples, purchase records, online listings, and technical comparisons. Consult a patent lawyer to evaluate the strength of your patent and infringement case, consider sending a cease-and-desist letter, and decide between administrative enforcement, civil litigation or customs measures. Preserve-time sensitive evidence by applying for evidence preservation with the court if needed.
You may file an invalidation request with CNIPA asking the patent to be revoked. Common grounds include lack of novelty or inventive step, or insufficiency of disclosure. Invalidation proceedings are administrative; unsuccessful parties can seek judicial review in the people’s courts. A coordinated invalidation-and-litigation strategy is common.
Remedies can include injunctions, seizure and destruction of infringing goods, an accounting of profits or monetary damages. Damages may be calculated based on actual loss, infringer gains, or statutory multiples in cases where precise losses are hard to prove. Recent legal changes have enabled higher awards and punitive-like damages for wilful infringement in serious cases.
Yes. Rights holders can apply to Chinese customs to record their patent and request border measures against suspected infringing imports or exports. Customs can detain goods suspected of infringement pending a rights-holder action. Consult counsel early because recordation and evidence requirements must be satisfied.
Costs vary widely. Filing and prosecution fees for invention patents include official fees and attorney or agent fees; utility models and designs cost less. Enforcement costs depend on whether you use administrative remedies or litigation, the complexity of the case, expert evidence, and length of proceedings. Budget estimates should include filing and translation costs, local representation fees, court fees and potential expert appraisal fees.
Yes. Many cities, including Xiamen, have local intellectual property service centers, government IP promotion programs, and incubation or technology transfer offices that assist small and medium enterprises with patent filing, searches and basic strategy. Local courts and administrative authorities may provide guidance on enforcement options. A patent lawyer can point you to the appropriate local offices and programs.
For patent matters in Xiamen you can rely on national and local resources for information and formal procedures. Useful types of resources include:
- The national patent office and its published rules and guidelines for patent prosecution and invalidation.
- Local intellectual property service centers and the Xiamen market supervision or intellectual property administrative departments for local administrative enforcement and filing assistance.
- Xiamen people’s courts for civil litigation and case handling; consult the court clerks for filing procedures and required documents.
- Customs offices in Xiamen for customs recordation and border enforcement measures.
- Professional organizations and bar associations that list registered patent attorneys and IP law firms active in Xiamen.
- International sources for procedural background such as WIPO and PCT materials when dealing with international filings and priorities.
If you need legal assistance with patents in Xiamen, follow these practical steps:
- Step 1 - Document the invention and collect all evidence related to creation, dates and any public disclosures.
- Step 2 - Arrange a patentability search and preliminary freedom-to-operate review with a qualified patent agent or lawyer.
- Step 3 - Decide on filing strategy - domestic filing, PCT application, or priority claim - and engage a China-registered patent agent to prepare and file the application in Chinese.
- Step 4 - If you face potential infringement, preserve evidence immediately, consult counsel about administrative versus judicial enforcement, and consider urgent preservation or injunctive measures.
- Step 5 - For disputes, retain counsel experienced in patent litigation and invalidation actions in China to coordinate actions before CNIPA, customs and the courts.
- Step 6 - Maintain an IP management plan - monitor filings and competitors, keep prosecution deadlines, and register any assignments or licenses with the relevant authorities.
Engaging an experienced patent lawyer or registered patent agent early will help you choose the right protection and enforcement path in Xiamen and avoid procedural pitfalls. If you are unsure where to start, contact a local IP law firm or the local IP service center for an initial consultation and a tailored action plan.
