Do I pay for another round, or fight it?
The honest answer depends on whether you disagree with the examiner or merely need different claims. If your claims need changing, an RCE gets that considered. If you believe the examiner is wrong on the art or the law and your claims are worth defending as written, that is what an appeal is for.
The cheapest move is worth trying first when the gap is small: an after-final reply that cancels claims or adopts language the examiner has already indicated would be allowable.
The three routes compared
| Route | Cost | Timetable | Best when |
|---|---|---|---|
| After-final reply (1.116) | Lowest | Weeks | The remaining gap is small and the amendment does not require new search |
| RCE (1.114) | Official fee plus preparation | A further examination cycle | You have substantive amendments that must be considered |
| Appeal (41.31) | Highest | Often well over a year | The examiner is wrong on the law or the art and the claims are worth defending as they stand |
Do not let the two-month point pass without deciding
The practical value of an after-final reply comes from filing it early enough that the examiner’s advisory action still leaves you room to file an RCE or an appeal. Filing at month three converts a choice into an emergency.
