What is a new ground of rejection in patent examination?

A new ground of rejection in patent examination refers to a rejection that introduces new prior art or a new statutory basis for rejecting a claim. However, the specific definition can be complex. The MPEP provides guidance on what constitutes a new ground of rejection in MPEP § 1207.03(a).

It’s important to note that not all new rejections are considered new grounds of rejection. For example, as stated in MPEP 706.07(a): “Where information is submitted in an information disclosure statement during the period set forth in 37 CFR 1.97(c) with a fee, the examiner may use the information submitted, e.g., a printed publication or evidence of public use, and make the next Office action final whether or not the claims have been amended, provided that no other new ground of rejection which was not necessitated by amendment to the claims is introduced by the examiner.”
