PRC Supreme Court Ruling: Late Amendments Cannot Trigger Divisional Patents Beyond Statutory Window

The Supreme People's Court of China ruled in Administrative Case (2026) Supreme Court IP Admin Final No. 392 that patent applicants cannot obtain additional procedural benefits through non-compliant amendments. Company J received a grant notice on March 3, 2021, and attempted on June 11, 2024, to trigger a second divisional application by making untimely amendments that created a lack of unity. The court deemed the divisional application not filed.

This ruling may be misinterpreted as a restriction on all divisional applications in China, but it only targets attempts to prolong application lifespans via non-compliant procedures. Applicants submitting voluntary divisionals within two months of receiving a grant notice or filing compliant amendments during substantive examination remain entirely unaffected. The ruling limits only those attempting to force passive divisional opportunities after the statutory window closes.

R&D and legal heads managing Chinese patent portfolios should audit divisional management timelines. Voluntary divisional applications must be filed within two months of receiving the grant notice. Any voluntary amendments must be submitted within three months of entering substantive examination or within the official response deadline.
