Abstract In fields of bio-engineering development and patent examinations, China and Japan have certain similarities. Specific to protein products, their criteria for inventiveness are basically the same. Meanwhile, Japan has the additional provision besides the case in China's "Guidelines for Patent Examination" in protein's novelty, as proteins differ from known ones only in terms of oligosaccharide chain is novel. China's invalidation case of No. 15463 and Japan's Heisei 14 No.505 precedent embody the examination standards, which have guiding significance in future's judgments.

Key words： Protein Patent Novelty Initiative Sino-Japan
