In a pivotal decision impacting common law trademark rights, the Fourth Circuit Court of Appeals vacated and remanded a summary judgment ruling favoring T-Mobile in Simply Wireless, Inc. v. T-Mobile US, Inc., 115 F.4th 266 (4th Cir. 2024). The case addressed critical issues surrounding trademark abandonment and the standard for demonstrating intent to resume use under the Lanham Act.
Background of the Dispute
Simply Wireless, a Virginia-based telecommunications company, claimed common law rights to the “SIMPLY PREPAID” trademark, first used in 2002 for selling prepaid airtime and related services. Between 2002 and 2008, the mark generated over $20 million in revenue for the company. However, Simply Wireless paused use of the mark from 2009 to 2011 due to industry changes, triggering a potential presumption of abandonment under the Lanham Act.
In 2014, T-Mobile began using the “SIMPLY PREPAID” mark for its retail operations and filed a trademark registration application. Simply Wireless filed its own competing application and initiated litigation, alleging trademark infringement and dilution. The district court granted summary judgment for T-Mobile, ruling that Simply Wireless had abandoned the mark during the period of nonuse.

The Fourth Circuit vacated the district court’s ruling, holding that Simply Wireless had presented sufficient evidence to raise genuine disputes of material fact regarding its intent to resume use of the trademark. Key findings included:
