The US Court of Appeals for the Federal Circuit affirmed the Trademark Trial & Appeal Board’s refusal to register a mark on the grounds of false connection, explaining that the false connection inquiry can include evidence that arises during the examination after filing. In re Thomas D. Foster, APC, Case No. 23-1527 (Fed. Cir. May 7, 2025) (Moore, Prost, Stoll, JJ.)

Under § 2(a) of the Lanham Act (15 U.S.C. § 1052(a)), a trademark can be refused registration if it “falsely suggests a connection with persons, living or dead, institutions, beliefs, or national symbols.” To determine if a mark falsely suggests a connection, the Board can use a non-exhaustive four-part test that inquires whether:

• The mark is the same, or a close approximation of, the name previously used by another person or institution.
• The mark points uniquely or unmistakably to that person or institution.
• That person or institution is not connected with the activities performed by the applicant under the mark.
• The fame or reputation of the person or institution is such that, when the mark is used with the applicant’s goods or services, a connection with the person or institution would be presumed.

Here, Thomas D. Foster filed a trademark application for the mark US SPACE FORCE on March 19, 2018, six days after President Trump proposed forming a “Space Force.” Registration was refused on the grounds of a false suggestion of a connection with the US government. The Board affirmed and denied reconsideration. Foster appealed.

Foster argued that the Board improperly considered evidence that post-dated the application’s filing date and that substantial evidence did not support the Board’s findings under the first two elements of the four-part false connections test.

Regarding Foster’s first argument, the Federal Circuit found it permissible to use facts that arise after an application’s filing date and during the examination process to assess a false connection. The Court reasoned that this was consistent with other § 2 inquiries that consider evidence that arises through the date the Board issues its decision, such as likelihood of confusion (§ 2(d)) and distinctiveness (§ 2(f)). Therefore, the Court found that the Board did not err in its consideration of evidence that arose during the examination process.

The Federal Circuit disagreed with Foster’s second argument, finding that substantial evidence supported the Board’s findings under the false connection test. Under the first part of the test, the Board found that US SPACE FORCE was the same as, or a close approximation of, a name or identity of the United States. The Court concluded that this was supported by substantial evidence, specifically pre-application evidence (President Trump’s announcement and national news articles discussing the formation of the US Space Force) and post-application evidence (the official establishment of the US Space Force and national news articles). Under the second part of the test, the Board had found that US SPACE FORCE pointed uniquely and unmistakably to the United States. The Board again relied on news coverage and the fact that the mark and the name of the military branch were identical. The Court determined this was sufficient for substantial evidence and therefore affirmed the refusal of registration.

Practice Note: To determine whether a false suggestion of a connection exists, the Board may consider evidence that arises during the examination process. The Board will typically use either the four-part false connections test or consider the factors identified by the Federal Circuit in Univ. of Notre Dame Du Lac v. J.C. Gourmet Food Imps. (1983) or In re E.I. du Pont de Nemours & Co. (1973).
