How does the examiner’s decision granting a reexamination request differ from determining patentability?
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 examiner’s decision granting a reexamination request focuses on whether there is a substantial new question of patentability (SNQ) or a reasonable likelihood that the requester will prevail (RLP), rather than determining the ultimate patentability of the claims.
According to MPEP 2646:
“In the decision on the request, the examiner does not decide the ultimate question of patentability of the claims. Rather, the examiner only decides whether there is a SNQ/RLP established sufficient to grant the request and order reexamination.”
This means that the examiner’s decision to grant reexamination is based on finding that the request has raised a substantial question or shown a reasonable likelihood of success, but does not involve a full examination of the claims’ patentability at this stage.
