On Monday, October 5, TradeSun Inc. filed a trademark lawsuit against OpenAI in the U.S. District Court for the Northern District of California (San Francisco). According to the complaint, OpenAI's flagship artificial intelligence model named Astra, introduced in September, infringes the trademark of the software that TradeSun has sold under that name since 2021. According to Reuters, the complaint was filed with the court on Monday itself, and legal publications were the first to report it.
Who TradeSun Is and What It Relies On
TradeSun is a software company that uses AI agents to analyze trade documents. Its main customers are banks and other financial institutions: the program is designed specifically to automatically analyze these organizations' trade documents. In its complaint, the company stated that it began selling software under the Astra name in 2021. In addition, according to Bloomberg Law, TradeSun registered the name Astra as a federal trademark in 2022 for artificial intelligence software services. In other words, the plaintiff is documenting its official rights to the name: first use in the market, then state registration — both steps are recorded in the complaint.
TradeSun's main argument to the court concerns the risk of consumer confusion. In the company's view, with the release of a flagship model of the same name from a world-famous AI lab like OpenAI, customers will no longer be able to distinguish between the two "Astras." As a result, the brand that has been forming since 2021 will be diluted, and the company risks losing control over its own name. This very concern occupies a central place in the complaint: this is not about an accidental similarity of names, but about the infringement of a registered trademark. Notably, although both legal outlets covered the story on Monday, October 5, they placed emphasis differently: Reuters focused mainly on the consumer-confusion argument and the chain of recent events around Astra, while Bloomberg Law detailed the 2022 federal registration, the plaintiff's monetary and injunctive demands, and the OpenAI spokesperson's comment.
The Plaintiff's Demands
TradeSun is asking the court for two types of relief. First — monetary damages in an amount not yet disclosed. The complaint does not specify an exact sum: the company is asking for the amount of damages to be determined during the proceedings. Second — a court order barring OpenAI from using the name "Astra." This demand is considered the sharpest part of the lawsuit: TradeSun is seeking not only compensation for the past period, but also a prohibition that would prevent OpenAI from keeping the model under that name on the market in the future.
The case is registered as "TradeSun Inc v. OpenAI Opco LLC, No. 3:26-cv-11360" in the U.S. District Court for the Northern District of California. The court is located in San Francisco. Both sources — Reuters and Bloomberg Law — confirm the lawsuit was filed on Monday, October 5.
OpenAI's Position
OpenAI rejected the allegations in the lawsuit. A company spokesperson assessed the complaint in a brief comment to publications:
"This complaint lacks any merit whatsoever."
The spokesperson's words mean the complaint is completely meritless. According to Bloomberg Law, OpenAI limited itself to this short sentence and has not yet commented in detail on the substance of the proceedings. The company maintains the position that it did not infringe third-party trademarks in choosing the Astra name — this can be inferred from the spokesperson's "meritless" assessment.
Recent Events Around Astra
Even before the lawsuit was filed, the name Astra was at the center of attention in the AI world. OpenAI introduced its flagship model on September 3. However, according to Reuters, the company canceled an updated version of Astra later that same month over safety concerns. Thus, exactly one month after the model's unveiling, on October 5, a trademark lawsuit was filed against it. The chronology of events looks like this: September 3 — Astra is introduced as the flagship model; during September — the updated version of the model is canceled over safety concerns; October 5 — TradeSun sues OpenAI in the San Francisco federal court. Astra is now at the center of disputes in two directions at once: on one side, safety questions around the model itself; on the other, a legal dispute over rights to the name. No official date has yet been announced for the next stages of the court proceedings.
