1212.04 Prior Registrations as Proof of Distinctiveness
Trademark Rule 2.41(a)(1), 37 C.F.R. §2.41(a)(1), provides that the examining attorney may accept, as prima facie evidence of acquired distinctiveness, ownership by the applicant of one or more active prior registrations of the same mark on the Principal Register or under the Act of 1905. See TMEP §1212.04(b) as to what constitutes the "same mark," and TMEP §§1212.09–1212.09(b) concerning §1(b) applications.
The rule states that, "in appropriate cases," ownership of existing registrations to establish acquired distinctiveness "may be accepted as sufficient prima facie evidence of distinctiveness," but that the USPTO may, at its option, require additional evidence of distinctiveness.
