An American film production company has claimed trademark infringement against Sony and developer Shift Up regarding the PS5 action-adventure hit, Stellar Blade.

Stellar Blade Sued By “Stellarblade” for Trademark InfringementBoth Trademarks Properly Registered

Shift Up, the developer of PS5 action-adventure hit Stellar Blade, and Sony have been sued by a film production company called "Stellarblade." The film company, based in the US state of Louisiana, alleged trademark infringement and filed the case in a Louisiana court earlier this month.

Griffith Chambers Mehaffey, the owner of the Stellarblade film company, claimed that their business, which specializes in "Commercials, Documentaries, Music Videos & Independent Films," has been harmed by Sony and Shift Up's use of the name "Stellar Blade" for the game. Mehaffey further stated that the name's use has reduced their business' online visibility, claiming that potential clients searching "Stellarblade" now have difficulty finding relevant information due to "Stellar Blade" game search results.

Mehaffey's request to the Court included monetary damages and attorney fees, as well as an injunction preventing Shift Up and Sony from using the "Stellar Blade" trademark, or any similar name. He also requested the Court to order the transfer of all "Stellar Blade" materials from the game companies to Mehaffey and his company Stellarblade for destruction.

Mehaffey registered the "Stellarblade" trademark in June 2023 and subsequently issued a cease and desist letter to Stellar Blade developer Shift Up the following month. In the lawsuit, Mehaffey asserted that he has owned the stellarblade.com website since 2006, used in conjunction with his film production company since 2011.

In a statement to IGN, Mehaffey's lawyer stated that it is "difficult to imagine that Shift Up and Sony were unaware of Mr. Mehaffey's established rights before adopting their identical mark." For further context, Stellar Blade was first announced as "Project Eve" in 2019, later renamed "Stellar Blade" in 2022. In January 2023, Shift Up reportedly registered the "Stellar Blade" trademark for its PS5 title. Mehaffey registered the "Stellarblade" trademark in June 2023, months after Shift Up's filing.

"Mr. Mehaffey registered the stellarblade.com domain in 2006 and has used the STELLARBLADE name for his business for nearly 15 years. We believe in fair competition, but when larger companies disregard the established rights of smaller businesses, it's our responsibility to advocate for and protect our brand," Mehaffey's lawyer told IGN in their statement. "The defendants’ significantly greater resources have effectively monopolized online search results for STELLARBLADE, pushing Mr. Mehaffey's long-established business into digital obscurity and jeopardizing the livelihood he's built over more than a decade." Furthermore, Mehaffey argued that both logos, as well as the stylized letter 'S' in both names, are points of contention and are "confusingly similar."

It is worth noting, in addition, that the rights of a trademark owner generally can be applied retroactively, meaning the trademark protection extends beyond the scope of the trademark's filing date.
