File Wrapper Analysis

What do we understand by file wrapper?

A patent file wrapper is a file that encloses all the paperwork related to the prosecution and opposition (if any) of a specific patent application. It is the comprehensive record of a patent application, including all relevant forms, receipts, drawings, block diagrams, and other papers. Any written or verbal correspondence between the examiner and the applicant is documented in the file wrapper. Popular names for the File Wrapper include File History and Prosecution History. There may be more than 1000 pages in a file wrapper, but for legal purposes, we just need the two lines that support our position. An extremely comprehensive inspection of the file wrapper is necessary in order to pinpoint those two particular lines. An attorney's review of tens of thousands of pages of file wrapper is incredibly wasteful.
