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.

According to MPEP 1207.03(c), the appellant has two months from the date of the examiner’s answer to respond to a new ground of rejection. The MPEP states:

“The two month time period for reply is not extendable under 37 CFR 1.136(a), but is extendable under 37 CFR 1.136(b) for patent applications and 37 CFR 1.550(c) for ex parte reexamination proceedings.”

This means that while the standard extension of time provisions do not apply, limited extensions may be available under specific circumstances.
