In theory China’s inventorship standard is similar to others around the world. An inventor is anyone who “makes creative contributions to the substantive features” of an invention. But what does this mean, and how does one apply this standard? Up to this point, this issue hasn’t really been litigated much in China (at least according to publicly available records). We finally have an important case (from the top!) that clarifies this issue. We analyse a binding judgment by the Intellectual Property Court of the Supreme People’s Court (SPC) of China1. It clarifies China’s applicable inventorship standards and the potential legal consequences of omitting qualified inventors. For U.S. companies conducting R&D…

However, in practice, Examiners and courts often disregard or devalue the inventive contribution of these “parameter features”, leading to considerable confusion among inventors. Recently, the China National Intellectual Property Administration (CNIPA) released the 2023 Compilation of Key Decisions in Patent Reexamination and Invalidation Cases.
