Ubisoft has filed trademark applications for the name Motherbrain, and the paperwork is almost entirely about artificial intelligence. The filings, first reported by Game File and picked up by Kotaku, cover AI software for making video games and interactive content, AI research and development, and “artificial intelligence as a service.”
Game File reports that Motherbrain is the name Ubisoft uses internally for its AI initiatives. The name also belongs, give or take a space, to Mother Brain, the biomechanical villain of Nintendo’s Metroid series. Kotaku reads it as a nod to Metroid. Nothing in the filings mentions Metroid, and Ubisoft hasn’t said where the name came from.
What the U.S. filings say
U.S. Patent and Trademark Office records show three applications for the standard-character mark MOTHERBRAIN, all filed September 7, 2026, by Ubisoft Entertainment of Carentoir, France. Each one sits in a different class:
- Serial No. 50094578, Class 9 (goods). It lists downloadable software using AI “for simulating natural conversation,” “for summarizing texts,” “for writing content based on a theme,” “for use in software development,” and “for creating video games and interactive content.” It also covers downloadable and recorded video game programs and “game engine software for video game development and operation.”
- Serial No. 50094580, Class 41 (entertainment services). It covers “providing online video games,” including browser-based and multiplayer games, plus production of video and computer game software, rental of video games, temporary use of non-downloadable games and “multimedia publishing of video game software.”
- Serial No. 50094582, Class 42 (software and research services). It covers AI research and consulting, “research, design and development of software using artificial intelligence,” “artificial intelligence as a service (AIAAS) featuring software using artificial intelligence for analyzing data and interacting with humans,” and software-as-a-service and AI-as-a-service offerings “for creating video games and interactive content.” It also lists video game programming and development services, including development for others.
All three were filed on an intent-to-use basis. That means Ubisoft hasn’t claimed it’s using the name in commerce yet, only that it plans to. When RCG checked the records around 5 PM CT Monday, all three were still waiting for a USPTO examining attorney to be assigned. No registrations have been granted.
An EU filing, too
Ubisoft also appears to have filed the name in Europe. EUIPO data listed by the trademark database TrademarkElite shows a MOTHERBRAIN application from Ubisoft Entertainment, No. 019419181, filed September 8, 2026, in French. It covers Classes 9, 41 and 42. The EU wording runs along similar lines, with AI chatbot software for simulating conversations, AI software for writing content based on a theme, software for processing, recognizing and generating images, sounds, video and text, and several forms of AI-as-a-service. The Class 9 and Class 42 lists both end by limiting those goods and services to the field of entertainment.
What Ubisoft has said
So far, nothing about Motherbrain. Kotaku notes there doesn’t appear to be any public messaging that uses the term. RCG found no Ubisoft statement about the filings either.
Ubisoft has been open about the individual AI projects, though. On X, Game File’s Stephen Totilo described Motherbrain as the internal name for the group handling Ubisoft’s previously announced generative AI game development projects involving NPC dialogue and FPS squadmates. Kotaku lists the public track record:
- GhostWriter (2023), an AI tool that helps writers on Far Cry and other big franchises generate NPC dialogue.
- Neo NPC (2024), a push to use AI for more dynamic side characters.
- Teammates (2025), which Ubisoft called its “first playable generative AI research project.” The small, Ghost Recon-style demo had AI-voiced allies who could react in real time to what the player was saying.
“Games of tomorrow will listen, understand, and react to players far more than today, and our research gives a glimpse of what adaptive, generative play could add on top of proven game systems,” Ubisoft’s director of GenAI gameplay, Xavier Manzanares, told Variety at the time, as Kotaku recounts.
Kotaku also points out that generative AI has turned up in Ubisoft’s games less deliberately. Anno 117: Pax Romana was caught with apparently AI-generated artwork that was later removed.
What a trademark does and doesn’t tell you
A trademark application reserves a name for a list of goods and services. It isn’t a product announcement. Companies often file broad descriptions to protect a name early, and a filing on its own doesn’t mean a product is coming. What these filings do show is how broadly Ubisoft wants the Motherbrain name protected: AI tools for building games, AI services for “interacting with humans,” and games themselves.
What Motherbrain actually is, and whether it ever shows up in front of players, is something only Ubisoft can answer. Until it does, all anyone has is the name and a long list of AI-heavy trademark wording.
