An applicant may file a motion during the interference to add or amend a claim. A patentee may file a reissue application in support of a motion to add or amend a claim. A copy of the paper adding or amending the claim will be placed in the official record of the application, but not entered. A decision on the motion is entered in the official record of the application. The examiner may enter the added claim or amended claim into the application only if, and only to the extent, authorized by the Board, typically in the decision on the motion. The decision authorizing entry of the added or amended claim does not prevent the examiner from rejecting the claim during further prosecution.
