TradeSun sues OpenAI for trademark infringement over the 'Astra' name of GPT-6 Astra
On Oct 5, 2026 TradeSun Inc., a compliance software company serving banks that has sold an AI product under the ASTRA brand since 2021, sued OpenAI in the Northern District of California (TradeSun, Inc. v. OpenAI OpCo, LLC, No. 3:26-cv-11360). It alleges that GPT-6 Astra causes "reverse confusion" and seeks an order removing the Astra name from OpenAI's products, plus profits and damages.
Key facts
- Case: TradeSun, Inc. v. OpenAI OpCo, LLC, No. 3:26-cv-11360 (N.D. Cal.), filed 2026-10-05 (CourtListener docket)
- TradeSun claims continuous use of ASTRA since 2021 and a 2022 federal registration covering AI software services
- Theory: reverse confusion. Customers may believe TradeSun's ASTRA is an OpenAI product or built on OpenAI models, or see TradeSun as an imitator; TradeSun says OpenAI markets Astra to banks and financial institutions for document interpretation, data extraction, risk screening and workflow automation, overlapping its own customers
- Relief sought: injunction against OpenAI's use of 'Astra', disgorgement of profits, damages (reports mention treble damages for wilful infringement)
- Counsel: Andrew Tutt and Stanton Jones (Trial Lawyers for Justice) and Ana Juneja (Ana Law LLC)
- TradeSun CEO Nigel Hook: 'Becoming one of the world's largest technology companies does not grant OpenAI the right to use our trademarks.' OpenAI: 'We take trademark rights seriously and are reviewing the complaint.'
- Earlier OpenAI naming disputes: io/iyO (2025) and Cameo vs Sora (2025)
What happened
Reuters and Bloomberg reported the suit on Oct 5. The complaint argues that OpenAI, an experienced trademark filer, could easily have found TradeSun's registration. Commentators note that TradeSun must show consumers are likely to be confused even though the two products serve different market segments. The Reuters article itself was not read directly; the details come from the docket and secondary write-ups.
Why it matters
Astra is OpenAI's flagship model brand ("GPT-6 Astra", "6.1 Astra"). An injunction, however unlikely, would force a rename. The case adds to the run of naming disputes OpenAI has faced over product brands.
