OpenAI faces trademark infringement lawsuit; the name "Astra" sparks legal disputes.

OpenAI is facing another trademark lawsuit. TradeSun, an AI software company, is accusing OpenAI of unauthorized use of the "Astra" trademark in its latest large language model and is demanding that the court order OpenAI to remove the product name and compensate for lost profits.

According to Bloomberg, TradeSun filed a lawsuit on Monday in the U.S. District Court for the Northern District of California. The company has been selling software products under the Astra brand since 2021 and obtained a federal trademark registration in 2022 covering AI software services.

TradeSun believes that OpenAI's GPT-6 Astra, released last month, is conveying the brand perception that "Astra is OpenAI" to consumers, constituting a typical case of "reverse obfuscation" infringement.

An OpenAI spokesperson responded via email, stating, "This lawsuit is completely unfounded, and we will continue to focus on responsibly building technology that benefits everyone." This case is the latest in a series of trademark lawsuits that OpenAI has faced in the same court, putting ongoing pressure on its branding strategy and product naming practices.

Core of the accusation: Risks of reverse confusion and market confusion

TradeSun cited the "reverse confusion" doctrine in its complaint, which states that the larger defendant misappropriated the smaller plaintiff's trademark, causing consumers to mistakenly believe that the smaller company's products were actually produced by or authorized by the larger company.

The lawsuit states that consumers encountering TradeSun's ASTRA brand may now mistakenly believe that the product belongs to OpenAI, is built on OpenAI models, or is sponsored and endorsed by OpenAI.

Worse still, consumers may view TradeSun as an imitator trying to piggyback on OpenAI's "Astra" brand.

TradeSun further points out that the two companies serve a highly overlapping customer base—OpenAI's Astra also targets banks, financial institutions, and corporate clients, providing services including business document interpretation, data extraction and verification, risk screening, and multi-step workflow automation, which is almost identical to TradeSun's business scope over the years.

New case added to OpenAI trademark dispute.

This lawsuit is not the first time OpenAI has encountered legal difficulties regarding trademark issues.

In February of this year, a federal judge prohibited OpenAI from using the name "cameo" in features related to its discontinued Sora video generation tool; two months later, another judge blocked its use of the "io" brand on AI devices. The "io" case was settled in July, while the "cameo" case is still pending.

All of these lawsuits were filed in the U.S. District Court for the Northern District of California, reflecting the brand compliance risks faced by the AI giant during its rapid product iteration.

TradeSun believes that OpenAI, as a mature company with extensive experience in trademark registration and protection, could have easily retrieved TradeSun's Astra registration information, but chose to use it without authorization, and is therefore to blame.

Plaintiff: Five years of brand investment cannot be misappropriated

TradeSun founder and CEO Nigel Hook stated in a press release:

"TradeSun built ASTRA from scratch, and for over five years we have continuously invested in technology research and development, customer maintenance, and brand building. We strive to create a product and brand that our clients can trust in every transaction. Becoming one of the world's largest technology companies does not grant OpenAI the right to use our trademarks."

In its lawsuit, TradeSun is asking the court to rule that OpenAI has infringed on its trademark, order it to remove the name "Astra" from all its products, and order OpenAI to pay the plaintiff all profits gained from the infringement. The company is represented by Trial Lawyers for Justice and Ana Law LLC.
