OpenAI Faces Trademark Lawsuit Over ‘Astra’ Branding in Latest AI Model Release

OpenAI is facing a trademark infringement lawsuit filed on October 5, 2026, by TradeSun Inc., a California-based software company. TradeSun alleges that OpenAI’s use of the name “Astra” for its latest AI model, GPT-6 Astra, infringes upon TradeSun’s existing trademark rights and could lead to consumer confusion.

TradeSun has been marketing its AI software under the “Astra” name since 2021 and secured a federal trademark registration for the name in 2022. The company’s Astra software utilizes AI agents to analyze trade documents for banks and other financial institutions. TradeSun contends that OpenAI’s adoption of the same name for its flagship AI model may cause customers to mistakenly associate the two products or assume an affiliation between the companies.

This lawsuit is not the first instance where OpenAI has encountered trademark disputes. In February 2026, OpenAI abandoned the “io” branding for its planned AI hardware devices following a trademark infringement lawsuit filed by audio startup iyO. The legal filings revealed that OpenAI decided not to use the name “io” (or any capitalization thereof) in connection with the naming, advertising, marketing, or sale of any AI-enabled hardware products.

Similarly, in October 2025, OpenAI faced a trademark lawsuit from celebrity video platform Cameo over the use of the name “Cameo” for a feature within its Sora AI-generated video application. The court granted a temporary restraining order, leading OpenAI to rename the feature to “Characters” and eventually discontinue Sora in April 2026.

These recurring trademark disputes highlight the challenges tech companies face in selecting product names that do not infringe upon existing trademarks. As AI technologies continue to proliferate, the importance of thorough trademark searches and clear branding strategies becomes increasingly evident to avoid legal entanglements and potential market confusion.
