Requirement to Identify Claim Source When Copied
Note:
Applicants must identify the patent and copied claims when submitting claims that are substantially copied from a patent, as required by 37 CFR 41.202(a). Failure to do so may violate the duty of disclosure under 37 CFR 1.56.

Where claims are copied or substantially copied from a patent, 37 CFR 41.202(a) requires the applicant, at the time he or she presents the claim(s), to identify the patent and the numbers of the patent claims. Clearly, the information required by 37 CFR 41.202(a) as to the source of copied claims is material information under 37 CFR 1.56 and failure to inform the USPTO of such information may violate the duty of disclosure.
