02/22/2010 - Don’t Rely on Reissue to Fix Your Patent Claims
Reissue is a post-issuance procedure that enables the correction of certain limited types of errors in a patent, but cannot be used merely for precautionary claim improvements. The Board of Patent Appeals and Interferences (BPAI) at the U.S. Patent & Trademark Office recently decided in a precedential opinion that reissue cannot be used to add a dependent claim “simply as a hedge against possible invalidity of the original claims.” Ex parte Yasuhito Tanaka, Appeal No. 2009-000234 (BPAI, Dec. 9, 2009) (per curiam).
