File Wrapper Document Code (FW_CODE)

For every document that the USPTO uploads into a patent or application's file wrapper, there is a specific code that is attached to it in the system.  These are codes that are standard USPTO codes.  For example, any Notice of Allowance sent has the code NOA added to the file wrapper, a Non Final Office Action has the code CTNF added to the file wrapper, etc.

  • FW_CODE:DIST --> Query matches all US patents or applications that have a terminal disclaimer filed.
