According to several media reports, the US software company TradeSun sued OpenAI on 5 October 2026 in the US District Court for the Northern District of California, saying that it has sold software products under the name Astra since 2021 and that OpenAI's AI model released under the same name will confuse consumers. TradeSun asks the court to bar OpenAI from using the name and to award damages. According to reports, the complaint relies on the theory of reverse confusion: a larger company that later adopts the same name may, through its greater reach, lead consumers to believe that the earlier user's products come from the larger company, are built on its models or are endorsed by it, or even to see the earlier user as the imitator. TradeSun also says that the two companies serve a highly overlapping customer base that includes banks, financial institutions and corporate clients.
According to reports, an OpenAI spokesperson said the lawsuit was without merit. The case is at the complaint stage and the court has made no finding on confusion or infringement.
The case is worth discussing because trade mark disputes are not only about small companies riding on big brands; they can run the other way. When a larger company that enters the market later has much greater reach, the public may come to believe that the smaller company which used the name first is the imitator. For businesses, the more useful focus is the risk in product naming, pre-launch searching and brand expansion.
J&C recommends making a trade mark search a fixed step before naming new products, models or features: the search should cover not only registered marks but also prior unregistered names in use, domain names, app stores and same-name products in the sector; when entering foreign markets or new business lines, search again by target market and class and file early; and smaller companies that are prior users should keep evidence of continuous use and register early where needed, so that they can assert their rights if a larger company launches a product under the same name.
