Protestor Can Submit Any Relevant Information
Note:
A protestor can submit any information they believe makes the patent grant improper, including evidence of fraud, inequitable conduct, or duty of disclosure violations.

Submissions under 37 CFR 1.291 are not limited to prior art documents such as patents and publications, but are intended to include any information, which in the protestor’s opinion, would make or have made the grant of the patent improper (see MPEP § 1901.02). This includes, of course, information indicating the presence of “fraud” or “inequitable conduct” or “violation of the duty of disclosure,” which will be entered in the application file, generally without comment on the inequitable conduct issues raised in it.
