302.01 Original Documents Generally Not Required
When a party files a copy of a document related to an application or registration, the USPTO will normally not require the party to submit the original document. Copies (e.g., photocopies or fax transmissions) are acceptable unless a document is required by statute to be certified (e.g., a certified copy of a final court order pursuant to 15 U.S.C. §1119). However, the party who filed the copy should retain the original in case questions arise as to the authenticity of the signature on the photocopy or faxed correspondence. 37 C.F.R. §2.193(b).
Original certificates of registration are not required for requests for amendment or correction of a registration under §7 of the Trademark Act, and owners are strongly discouraged from submitting them. TMEP §§1609.01(b), 1609.10.
