The Trademark Office requires on certain documents, such as an application for registration, a declaration by the trademark owner that all the information in the document is true. Specifically, 37 CFR 2.22 states the requirement:
Section 2.20 Declarations in lieu of oaths.
The applicant or member of the firm or an officer of the corporation or association making application for registration or filing a document in the Patent and Trademark Office relating to a mark may, in lieu of the oath, affidavit, verification, or sworn statement required from him, in those instances prescribed in the individual rules, file a declaration that all statements made of his own knowledge are true and that all statements made on information and belief are believed to be true, if, and only if, the declarant is, on the same paper, warned that willful false statements and the like are punishable by fine or imprisonment, or both (18 U.S.C. 1001), and may jeopardize the validity of the application or document or any registration resulting therefrom.
