File wrapper/PAIR analysis
As a patent application goes through multiple reviews, changes and updates during the examination process, all correspondence between the patent office examiner and the applicant is documented in the application’s file history.
A file history consists of valuable information related to the patent application. It communicates all the correspondence exchanged between the applicant and the examiner. The statements provided by the applicant during exchanges may be crucial to support licensing, litigation, and patent transactions. The applicant can make an amendment to the application to circumvent Examiners objections.
