A trademark infringement lawsuit filed on Monday puts a spotlight on something most AI teams rush through: the product name. TradeSun, a small AI software company in Del Mar, California, has sued OpenAI over the name of its GPT-6 Astra model.

TradeSun says it has sold software called Astra since 2021. OpenAI says the complaint has no merit. A court has not ruled on anything yet.

I coordinate software projects for clients in India and the USA, and naming comes up in almost every product launch. This case is a useful reminder that a name can turn into a legal problem months after launch. Here is what the lawsuit says, and the simple name check process I think every agency should follow.

What the OpenAI Astra Trademark Infringement Lawsuit Says

The case is TradeSun Inc. v. OpenAI OpCo LLC, No. 3:26-cv-11360. It was filed on October 5, 2026, in the US District Court for the Northern District of California. The details below come from Bloomberg Law's report on the complaint by Annelise Levy, with Reuters reporting the same core facts.

TradeSun's main claims

TradeSun has sold software under the Astra name since 2021.
It holds a federal trademark registration for Astra covering AI software services, granted in 2022.
OpenAI released GPT-6 Astra in September 2026.
TradeSun says both products serve the same kind of customers: banks, financial institutions and other enterprises.
It argues that OpenAI, which registers and enforces its own trademarks, could easily have found the existing Astra registration.

According to the complaint, OpenAI's Astra does the same work TradeSun has done for years. That includes reading business documents, extracting and reconciling data, screening for risk and automating multi-step workflows.

What TradeSun wants from the court

An order requiring OpenAI to remove the Astra name from all its products.
A judgment that OpenAI infringed its trademark.
The profits OpenAI earned from using the name, plus damages that Reuters reports are unspecified.

What both sides said

TradeSun founder and CEO Nigel Hook said in a statement: "Being one of the biggest technology companies in the world does not entitle OpenAI to our trademark."

An OpenAI spokesperson told Bloomberg Law: "This complaint lacks any merit whatsoever. We remain focused on responsibly building technology that benefits everyone."

Keep in mind that these are allegations. OpenAI will get to respond in court, and the outcome is open.

Reverse Confusion: The Twist in This Case

Most people picture trademark infringement as a small brand copying a famous one. This case is the reverse. TradeSun says the bigger company's launch is swamping the smaller company's name.

Lawyers call this reverse confusion. The worry is not that buyers think TradeSun is OpenAI. The worry is that buyers start to think TradeSun's product belongs to OpenAI, or that TradeSun is the copycat.

The complaint puts it plainly. It says customers who see TradeSun's ASTRA are now likely to assume the product "is OpenAI's, is built on OpenAI's model, or is offered with OpenAI's sponsorship or approval, or, worse, that TradeSun is the imitator trying to latch onto OpenAI's Astra brand."

TradeSun also says OpenAI is "teaching the public that Astra means OpenAI." For a small company, that is a real business risk. Its own customers could start to doubt where the product came from.

This Is Not OpenAI's First Naming Fight

Bloomberg Law notes that this is one of several trademark cases OpenAI has faced in the same court:

Cameo: In February 2026, a federal judge barred OpenAI from using "cameo" for features in its now-defunct Sora video generator. That case is still pending.
io: In April 2026, another judge blocked OpenAI from using "io" branding for AI-powered devices. That dispute settled in July.
Astra: Now TradeSun has filed its claim over the GPT-6 Astra name.

Three naming disputes in one year tells you something. Even a company with large legal and brand teams can pick names that collide with existing businesses.

There is another detail worth knowing. US Patent and Trademark Office records show that TradeSun's own Astra registration was challenged earlier this year. A company called BizUpUSA Holdings filed a petition to cancel it in April 2026. That petition was withdrawn, and the board denied the cancellation with prejudice in July. Short, catchy names attract more than one claimant.

Why Trademark Infringement Matters for AI Products Built by Agencies

Agencies name things all the time. We name client apps, chatbots, internal AI assistants, browser extensions and SaaS features. Many of these names are picked in a sprint planning call and never checked.

That habit was risky before. With AI products, it is riskier for three reasons:

Popular words get reused. Names like Astra, Nova, Atlas and Echo show up across many AI tools. The more appealing the word, the more crowded it is.
AI launches spread fast. A client's chatbot can go from a pilot to an app store listing in weeks. A name conflict found late costs more to fix.
Software crosses borders. A product built in India for a US client is often sold in both markets. Each country has its own trademark register.

A forced rename is expensive. You may need new domains, new app store listings, new marketing material, fresh SEO work and a lot of client explaining. That is before any legal costs.

The Astra name already had a busy year. We looked at how GPT-6 Astra behaved in agent testing last month. Now the same name is at the center of a legal fight.

A Simple Trademark Check Process for Agencies

You do not need a law firm on retainer for every feature name. But you do need a repeatable check before anything goes public. This is the process I would use.

Shortlist three to five names. Never fall in love with just one. Your first choice may already be taken.
Search the US register. Use the USPTO trademark search system to look for exact and similar marks in software and AI classes, such as Class 9 and Class 42.
Search the Indian register. IP India runs a public trademark search. Check it for clients who sell in India or plan to.
Search globally. The WIPO Global Brand Database lets you search marks across many national registers in one place.
Check real-world use. Search app stores, GitHub, Product Hunt and plain web results. TradeSun's claim rests on years of actual sales, not only a registration.
Look at the customer overlap. A similar name in a very different market carries less risk than one aimed at the same buyers.
Document what you found. Save screenshots and search results with dates. TradeSun argues that OpenAI could easily have found its registration, so a record of honest checks helps.
Get legal sign-off for launch names. For anything customer-facing, ask a trademark lawyer to review the shortlist. It costs far less than a rename.

Quick risk guide

What you find	Risk level	What to do
Same name, registered for AI or software	High	Drop the name and pick another
Same name, used by a software company but not registered	Medium to high	Get legal advice before using it
Similar name in an unrelated industry	Lower	Note it and confirm with a lawyer
No matches in registers or real-world use	Low	File your own application early

Who Owns the Name: Agency or Client?

This question trips up a lot of agency contracts. If your team suggests a product name, who is responsible when it turns out to clash with someone else's mark?

Spell it out in the statement of work. These points help:

Who picks the final name. Usually the client, even if the agency suggests options.
Who runs and pays for clearance. Agree whether the agency does a basic search and the client handles legal review.
Who files the trademark. The client should own the mark for its own product.
What happens if a rename is needed. Agree on how rebranding work will be scoped and billed.

This sits alongside other AI legal questions agencies now face. Our breakdown of what the Westlaw vs ROSS ruling means for AI copyright covers the training data side. Naming is the brand side of the same problem.

A Quick Example From Client Work

Picture a Bengaluru agency building an AI document assistant for a US lender. The team calls it "Orion" during development, and the name sticks. The client loves it and prints it on the sales deck.

Two weeks before launch, a quick search finds a registered "Orion" mark for document software, owned by a fintech vendor. The fix now means new branding, new domains and a delayed launch.

Run the same search in week one and the story changes. The team drops Orion, picks a clear name from the shortlist, and the client files an application early. Nobody loses sleep.

What Happens Next in the Astra Case

OpenAI will file its response in court. No hearing date had been reported at the time of writing. Any ruling on whether OpenAI can keep using the name is still ahead.

Whatever the outcome, the lesson for agencies is already clear. A name is a business asset, and checking it is part of shipping a product.
