Ex Populus, the Delaware corporation behind Ethereum’s blockchain-powered gaming network Xai, has taken legal action against Elon Musk’s artificial intelligence company xAI for trademark infringement. The lawsuit focuses on the confusion in the marketplace between Ex Populus’s XAI trademark, which has been federally registered since June 2023, and Musk’s xAI company, which was announced in July 2023.
Ex Populus is a leading blockchain gaming network that offers AI-driven gaming solutions and autonomous software systems across multiple platforms. Musk’s announcement of xAI entering the AI gaming studio space in November 2024 directly encroached on Ex Populus’s established territory. This led to widespread confusion among consumers, with over 36 million viewers being exposed to the competing brands.
The legal complaint highlights instances where xAI’s AI assistant Grok mistakenly referred to xAI’s gaming initiatives as “XAI_GAMES,” further fueling the marketplace confusion. The association with Musk’s controversial public image also tarnished Ex Populus’s brand reputation, especially when xAI’s Grok chatbot was taken offline for promoting violence and making racist comments.
The U.S. Patent and Trademark Office has already suspended several of Musk’s trademark applications for “xAI” and “XAI GROK” due to the likelihood of confusion with Ex Populus’s prior rights. Despite attempting to acquire senior trademark status by purchasing an abandoned “X.AI” registration, Ex Populus argues that the previous owner had already abandoned the mark in October 2021.
In response to the lawsuit, Musk’s legal team threatened Ex Populus with cancellation proceedings to pressure them into relinquishing their trademark rights. The updated lawsuit seeks a permanent injunction against xAI using the disputed marks, as well as the cancellation of existing trademark registrations and pending applications. Ex Populus is also seeking monetary relief, including disgorgement of profits, actual damages, treble monetary relief under federal law, and punitive damages under state law.
Aside from the trademark dispute, xAI has announced plans to sue Apple over alleged antitrust violations, claiming unfair treatment in the App Store rankings. This legal battle adds to a growing trend of intellectual property disputes within the crypto and blockchain space.
The lawsuit comes at a challenging time for Ex Populus’s XAI token, which has seen a significant decline in value. A successful legal outcome could potentially boost the token’s market performance, with speculation that Musk may consider acquiring the gaming company to resolve the conflict.
Overall, the lawsuit between Ex Populus and xAI underscores the importance of protecting intellectual property rights in a rapidly evolving industry. As both companies navigate the legal complexities of trademark infringement, the outcome of this case could have far-reaching implications for the future of blockchain gaming and AI technology.
