As of January 1, 2026, the China National Intellectual Property Administration (CNIPA) has implemented significant updates to the Guidelines for Patent Examination (under Order No. 84). These changes specifically affect how inventor and applicant information must be submitted in patent applications.
For our international clients, a notable update comes from a recent clarification issued by the CNIPA Department of International Cooperation on January 15, 2026 (Document No. [2026]007), which simplifies the filing process for foreign inventors.
Below are the key takeaways regarding these new requirements.
1. Foreign Inventors: ID Numbers No Longer Mandatory
Acknowledging the vast differences in identity documentation across various countries, the CNIPA has adjusted its system requirements to facilitate smoother filings for overseas applicants.
- Simplified Submission: For any inventor or designer who is not a Chinese national, providing the “ID Type” and “ID Number” in the patent business handling system is no longer mandatory.
- Public Record: The publicly available patent information will strictly display the name(s) of the inventor(s) or designer(s).
- Core Requirement: While specific ID numbers are optional for foreign nationals, the fundamental requirement to list the true identities of all inventors remains in effect to ensure authenticity.
2. Chinese Inventors: Full Identity Verification Required
In contrast to the flexibility granted to foreign nationals, strict identity verification remains in place for domestic inventors to ensure data accuracy.
- Mandatory Details: For any inventor or designer holding Chinese nationality, it is mandatory to provide their full identity information, including their valid ID number (e.g., Resident Identity Card number).
- Authenticity: Applicants must ensure that all submitted information regarding Chinese inventors is complete and authentic.
3. Updated Applicant Contact Requirements
To improve communication efficiency during the examination process, the CNIPA has also updated the requirements for applicant contact details.
- Phone Number is Mandatory: According to Section 4.1.7 of the Guidelines, when submitting a patent application or requesting a bibliographic change for an applicant, a valid contact telephone number for the applicant must be provided.
