Sony Opposes Naughty Cat Trademark Registration in the U.S. Over Similarity to Naughty Dog

Sony Interactive Entertainment has filed a request with the United States Patent and Trademark Office (USPTO) to oppose the registration of the trademark Naughty Cat, citing its similarity to the Naughty Dog studio’s name. Naughty Dog is known for developing the acclaimed duology The Last of Us, as well as the Uncharted and Crash Bandicoot series.

Naughty Cat is a Hong Kong-based company that has developed two mobile games available on the App Store.

SIE’s lawyers argue that the Naughty Cat trademark is so similar to Sony’s Naughty Dog trademark that it could cause confusion in the commercial perception and meaning for consumers. They point out that the most prominent element in both names, «Naughty,» is identical.

As for the second elements—Dog and Cat—they are also closely related, both representing domestic animals. The lawyers expressed concern that the similarity in names could mislead consumers into believing that Naughty Cat is affiliated with SIE and that its products are licensed and endorsed by Sony.

They argue that any trademark registration for Naughty Cat could lead to confusion, mistakes, and deception among the public regarding the origins of the applicant’s goods. This situation could harm both SIE and the consumers, according to representatives of the Japanese company.

The application to the USPTO indicates that the first use of the Naughty Cat trademark dates back to December 25, 2023. In contrast, the Naughty Dog trademark has been in existence for a significantly longer period, with its first major game, Crash Bandicoot, released in 1996.

The USPTO has set a timeline for resolving the dispute and established dates for court proceedings should Sony decide to file a lawsuit. Naughty Cat must respond to SIE’s objections by July 12. If they fail to do so, the USPTO may reject the application; otherwise, the matter will proceed to court in 2026.
