The Shanghai Intellectual Property Administration, or SIPA, provides administrative adjudication services for patent infringement disputes.

This service is governed by the Patent Law of the People's Republic of China, its implementing rules, and municipal administrative adjudication regulations. It applies to individuals, enterprises, public institutions, and social organizations within Shanghai's jurisdiction.

Key information

The service operates under a commitment-based approval system, with a statutory handling timeframe of five working days and no administrative fees.

Applicants can submit filings through online portals, at service windows, or by mail.

Required documents

Applicants must provide complete, compliant materials. Each case may involve only one patent number and one respondent; where multiple patent numbers or multiple respondents are involved, separate requests must be filed and separate cases registered. Applicants must also provide one copy of the request and the relevant evidence for each respondent:

• Petition for Handling a Patent Infringement Dispute;
• Documents proving the claimant's identity or entity qualification (An individual shall submit a resident identity card or other valid identification document. A legal person or unincorporated organization shall submit a copy of its valid business license or other document proving its entity qualification, together with proof of identity of its legal representative or person in charge. If the claimant is an interested party, supporting documents shall also be submitted);
• A copy of the patent register issued by the China National Intellectual Property Administration. For a utility model or design patent, the competent authority may also require a patent right evaluation report issued by the China National Intellectual Property Administration; if such a report is required and the claimant fails to submit it without a justified reason, the request may not be accepted;
• Documents relating to the verification of the respondent's identity or entity qualification information;
