How to claim acquired distinctiveness under Section 2(f)

You may submit actual evidence that the applied-for mark has acquired distinctiveness under Section 2(f) in connection with applicant's goods. In other words, because of the extensive use and promotion of the mark, consumers now directly associate the mark with the applicant as the source of those goods. Note: Long-term use alone is generally not sufficient to show acquired distinctiveness for marks that are merely ornamental.

Acceptable evidence of use and promotion can include:

(a) advertising and promotional materials that specifically show or promote the applied-for mark in use as a trademark and source-identifier;

(b) dollar figures for advertising devoted to such promotion;

(c) dealer and consumer statements indicating recognition of the applied-for mark as a trademark;

(d) other evidence that shows consumer recognition of the applied-for mark as a trademark for applicant's goods.

NOTE: For applications filed under Section 44 or 66(a), when providing evidence of long term use, an applicant may rely only on use in commerce that the U.S. Congress may regulate. Use solely in a foreign country or between two foreign countries never supports evidence of acquired distinctiveness in the United States.

For more information on Section 2(f), see 37 C.F.R. §2.41(a); TMEP §§1202.03(d), 1212.06 et seq.
