Rejection rates on closed invention cases over the same period were 0 in 2024 and remained low in 2025-2026 (the platform chart carries no figures for those years, so none are stated here). 2026 is a partial year to the retrieval date and its closed-case sample is incomplete, so the rate for that year will continue to move as further cases close.

Source and scope
China National Patent Agency Public Service Platform (operated by the All-China Patent Attorneys Association) · retrieved 25 October 2026 · original record: www.pppas.net/dljg/detail/5867
The figures cover this agency’s patent prosecution work only. They exclude trademark, copyright, software copyright, IC layout-design and other IP matters, and exclude cases handled previously under other entity names.
The platform charts cover a five-year window, but this agency’s records for 2023 and earlier are incomplete (data labels overlap on the grant chart and cannot be read reliably), so only 2024-2026 is shown here.
The platform currently publishes no data for reexamination and invalidation volumes or for patent litigation volumes; its domestic-versus-foreign case chart shows that domestic cases make up the large majority, with a small proportion of Hong Kong, Macao, Taiwan and overseas cases. For foreign-related and litigation work, see the case studies page.
