Patent reexamination is a review process initiated when an applicant disagrees with a rejection decision issued during substantive examination. It is conducted by a reexamination panel from the Patent Reexamination and Invalidation Department of the CNIPA, who were not involved in the initial rejection.

In the rapidly evolving landscape of Artificial Intelligence, defining the demarcation between "mathematical algorithms" and "patentable technical solutions" has become a cornerstone of global IP strategy. By comparing recent invalidation decisions from the China National Intellectual Property Administration, specifically Cases No. 586065, 584244, and 588362, with the U.S. Federal Circuit’s ruling in Recentive Analytics v. Fox Corp., we can discern critical jurisdictional nuances in how the validity of AI patents is adjudicated.

The SPC's ruling establishes that while the Patent Office can verify priority ex officio, it cannot use "secrecy" to bypass due process. This decision serves as a critical precedent for practitioners, signaling that any evidence used to strip a party of their IP rights must be brought "into the light" through formal cross-examination.

Digital Health in 2026 has moved from a “cool trend” to a high-stakes business and clinical reality.

CNIPA’s January 7, 2026 National IP Directors’ Meeting work report sends a clear signal for 2026: enforcement attention will not be limited to high-profile event-term squatting. CNIPA indicates it will (1) continue cracking down on bad-faith conduct that violates the principle of good faith, such as trademark squatting and hoarding; and (2) step up governance of "misleading wordplay trademarks".
