In 2025, a patent dispute between Chinese companies in the camera-module space pulled in attention from across the industry. The case, SUNNY v. AAC, produced rulings from China's Patent Reexamination and Invalidation Department — including Decision No. 566288 and related decisions — that ended with 11 patents invalidated.
IPWatchdog's coverage frames the outcome as a warning for U.S.-trained drafters: specifications that would count as high quality under U.S. standards can encounter fatal problems when tested in China. Drafting choices that serve applicants well in the U.S. system may not hold up under Chinese invalidation practice.
Because this article rests on a single report, there are no differing sources to weigh. Even so, the report's lesson is direct: patent quality is jurisdictional, and what survives in the U.S. may not survive in China.
