In U.S. patent law, Rule 56 (37 CFR § 1.56) imposes a duty of candor and good faith on all individuals involved in a patent application to disclose material information to the U.S. Patent and Trademark Office (USPTO). This means they must submit all known information that is important (material) to patentability, such as prior art, or risk the patent being held unenforceable for inequitable conduct if withheld with deceptive intent. Material information includes anything that creates a prima facie case for unpatentability or refutes the applicant's arguments, under a "reasonable examiner" standard.
