Reduction to Practice, Constructive

Filing a patent application that explains how to make and how to use an invention in sufficient detail that a person skilled in the art could practice the invention. MPEP 2138.05.


Examination of the patentability of an invention claimed in an issued U.S. patent at the request of the USPTO, the patent owner or a third party. MPEP 2209, MPEP 2210.

Rejection, Final

A rejection of a claim that occurs on the second or any subsequent examination of its patentability. After the final rejection of a claim occurs, the only recourses of an applicant are to argue that the final rejection was premature, to appeal the rejection or to amend the claim in accordance with any suggestion of the Examiner. The Examiner may allow the applicant to place the claim in better form for appeal. One interview with the Examiner will be allowed, if in the judgment of the Examiner, circumstances warrent the interview. See Rejection. MPEP 706.07, MPEP 706.07(a).

A U.S. patent application that was unavoidably or unintentionally abandoned, can be revived by petition. MPEP 711.


Withdrawing the protections associated with a patent grant.

Right of Priority
