I managed to mess up and filed a terminal disclaimer shortly after the Examiner had already responded with a final office action. The Examiner made it clear in their response that the claims were allowable, and that all issues had been addressed except the non-statutory double patenting issue that the terminal disclaimer was meant to obviate.
So technically the patent is now in a condition for allowance.
AFCAP 2.0 doesn't apply, because I would need to amend a claim (and they're all fine).
Do I have to file an RCE purely because of this, or is there some other (cheaper) way to get the patent granted?
