Nintendo Sues Accessory Maker Genki Over Switch 2 Leaks and Trademark Infringement

Nintendo is taking a firm stance against leaks and unauthorized use of its intellectual property. The gaming giant has filed a lawsuit against Genki, an accessory manufacturer, alleging trademark infringement, unfair competition, and false advertising related to the unreleased Nintendo Switch 2. This legal action highlights the intense secrecy surrounding Nintendo's upcoming console and the lengths the company will go to protect its brand.

The lawsuit stems from Genki's actions at the Computer Electronics Show (CES) 2025, where the company showcased 3D-printed mockups of the Switch 2 and discussed accessories purportedly compatible with the unannounced console. Nintendo claims that Genki’s CEO, Edward Tsai, even stated that the company had access to an authentic Switch 2, fueling speculation and confusion among fans and media outlets.

According to the lawsuit, Genki's actions were designed to capitalize on the public's anticipation for the new console and create the false impression of a partnership with Nintendo. In court documents, Nintendo states that Genki representatives, including Tsia, did multiple interviews about specific and highly confidential designs and functionality of the console. The company claims that these actions not only infringed on Nintendo's trademarks but also misled consumers regarding the compatibility and authenticity of Genki's products.

Nintendo also took issue with Genki's marketing tactics, including a social media post suggesting an "infiltration" of Nintendo's Kyoto headquarters. Furthermore, the lawsuit highlights Genki's decision to host its own "Direct" presentation shortly after Nintendo's official Switch 2 announcement, using a similar format and imagery that could have confused viewers. In fact, the said presentation featured a Nintendo Switch 2 render labelled “Genki Glitch 2”.

Nintendo is seeking damages, including the destruction of all products and marketing materials related to the Switch 2 and a permanent injunction preventing Genki from continuing its alleged infringing activities. The lawsuit also demands that Genki hand over any profits made from the unauthorized sales. The case is set to be heard in the U.S. District Court for the Central District of California.

This lawsuit sends a clear message to accessory manufacturers and other companies that Nintendo will vigorously defend its intellectual property rights and protect its brand image. The outcome of this case could have significant implications for the accessory market and the way companies approach the launch of highly anticipated Nintendo products.
