What happens if a patent owner doesn’t file a submission after an ACP?
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.
If a patent owner doesn’t file a submission after an Action Closing Prosecution (ACP) in inter partes reexamination, the following occurs:
- The third party requester is precluded from filing comments under 37 CFR 1.951(b)
- A Right of Appeal Notice (RAN) will be issued
- The patent owner does not lose any rights of appeal
MPEP 2672 states: “If the patent owner does not timely file comments or a proposed amendment pursuant to 37 CFR 1.951(a), then the third party requester is precluded from filing comments under 37 CFR 1.951(b). Accordingly, a Right of Appeal Notice (RAN) will be issued where the time for filing the patent owner comments and/or amendment has expired and no patent owner paper containing comments or amendment has been received.”
