Overview: | Antibody drug inventions have sometimes been registered with no sequence limitations. We studied 400 recent patent cases and discovered that about 30% of such inventions were granted with no sequence limitations. More importantly, about 10% of the inventions were granted just by defining the antibody function, competitive antibody, or antigen (epitope). There was a trend that claims defined with the antibody function, competitive antibody, or antigen (epitope) were more accepted in Japan and Europe than in the U.S. https://system.jpaa.or.jp/patent/viewPdf/3567 |
