What is the purpose of the statement applying prior art in an inter partes reexamination request?
This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.
The purpose of the statement applying prior art in an inter partes reexamination request is to explain how the cited prior art is applicable to the claims of the patent for which reexamination is requested. According to MPEP 2617:
“The request must include a statement applying the cited prior art (the patents and printed publications) to every claim for which reexamination is requested.”
This statement helps the USPTO examiner understand the requester’s perspective on why the cited prior art is relevant and potentially invalidates the patent claims.
