                        CHAPTER 3.   THE  LAW   OF  TRADEMARKS

                   TOPIC  4. DEFENSES   AND  LIMITATIONS ON RELIEF

§ 30. Abandonment

C.A.4, 2025. Com. (a) cit. and quot. in ftn. to diss. op. Manufacturer of low-speed open-air vehicles
filed a trademark infringement claim against competitors that asserted ownership of a mark used by all
parties and applied to register the mark, seeking declaration that it owned the trademark. After a bench
trial, the district court found that the mark was a generic term for the parties' vehicles and was not a
trademark that could be owned. This court vacated and remanded, holding that the district court did not
have sufficient evidence to determine whether the mark was generic. The dissent argued that the mark
was an inherently distinctive term and that the parties were seeking to claim a novel trademark that had
been abandoned, citing Restatement Third of Unfair Competition § 30 in noting that, although in some
instances subsequent users of an abandoned mark could be required to avoid deceptive
misrepresentations that attempted by falsehood to pass off' the source of the new product as the
original trademark owner, subsequent users owned the trademark and were otherwise free to use the
abandoned designation. Moke America LLC v. Moke International Limited, 126 F.4th 263, 297.

C.A.4, 2024. Cit. in cases cit. in sup., com. (a) quot. in sup. Telecommunications company sued
competitor, alleging that competitor infringed company's common-law ownership of a trademark. The
district court granted summary judgment for competitor, finding that, although company had acquired
common-law  ownership rights in the mark, it had abandoned the mark for lack of use for three
consecutive years. This court vacated and remanded, holding that there were genuine issues of material
fact that could overcome the presumption of abandonment, and that the statutory abandonment test
under the Lanham Act applied in an ownership dispute concerning a common-law trademark. The court
rejected competitor's contention that the Lanham Act did not apply to disputes over common-law
trademarks, pointing out that sister circuits and Restatement Third of Unfair Competition § 30 applied
the abandonment test to infringement claim at common law as well as to claims for the infringement of
marks registered under the Act. Simply Wireless, Inc. v. T-Mobile US, Inc., 115 F.4th 266, 285.
