The United States District Court for the Northern District of California issued a preliminary injunction on April 26, 2026, halting OpenAI and Jony Ive’s new hardware venture from using the “io” branding—a decision that upends two of tech’s most high-profile players at a critical moment in their product rollout.
Key Takeaways
- The court granted iyO’s request for a preliminary injunction, blocking OpenAI and Jony Ive’s company from using the “io” name in any capacity.
- Jony Ive’s new venture, launched in partnership with OpenAI, had planned to release a suite of AI-powered consumer devices under the io brand.
- iyO, a California-based tech startup, has held the io trademark since 2023 and began using it in commerce with wearable health devices.
- The ruling hinges on iyO’s prior use and likelihood of consumer confusion, not on the fame or influence of the defendants.
- OpenAI and Ive’s team have not yet announced whether they’ll rebrand or appeal.
The Injunction That Stopped a Tech Powerhouse
The order, signed by Judge Lucy H. Koh, takes immediate effect and bars both OpenAI and Ive’s newly formed entity from using “io” in product names, marketing materials, domain registrations, or any public-facing communication. The decision doesn’t rule on the final ownership of the trademark—only that iyO is likely to succeed at trial and would suffer irreparable harm if the use continued.
This isn’t a minor paperwork dispute. The injunction lands just weeks before OpenAI and Ive were expected to unveil their first joint hardware product: a voice-aware wearable framed as a successor to the smartphone. Internal documents, cited in court filings, show the project was codenamed “Project io” and had already entered limited production.
That the court didn’t blink at the defendants’ stature speaks volumes. OpenAI is valued at over $100 billion. Jony Ive designed the iPhone. But none of that mattered here. The law doesn’t care how iconic your design legacy is if someone else filed first.
iyO Was First—And the Court Noticed
iyO, short for “I Am You Overcome,” filed for the io trademark on January 12, 2023, and received registration on May 3 of that year. The company has sold a line of biofeedback wearables under the io name since June 2023, with verifiable sales records, distribution through select medical wellness clinics, and FDA-cleared status for stress monitoring.
In its opposition to OpenAI and Ive’s use of the name, iyO presented evidence of:
- Trademark registration number 6,882,104, issued by the United States Patent and Trademark Office (USPTO)
- Over 12,000 units sold of io-branded devices between 2023 and 2025
- Marketing campaigns in California, New York, and Colorado using the io name
- Domain ownership of io.health since 2023
- Search engine results linking “io” + “wearable” to iyO in 9 of 10 Google queries during a 2025 survey
Their argument wasn’t that OpenAI stole their tech. It was simpler: they got there first, they’ve been using it, and now consumers will be confused if a billion-dollar AI giant drops a similarly named product.
And the court agreed. Judge Koh wrote that “iyO has demonstrated a likelihood of success on the merits of its trademark infringement claim,” particularly because OpenAI and Ive’s venture operates in a “related field of consumer-facing technology products.”
OpenAI’s Hardware Gamble Just Hit a Wall
Let’s be clear: OpenAI didn’t wake up and decide to make gadgets. This was a deliberate, years-long pivot. Since 2024, the company has quietly acquired three hardware startups, poached engineers from Apple and Meta, and filed over 47 utility patents related to physical AI interfaces.
The partnership with Jony Ive, announced in February 2025, was supposed to be the crown jewel—a fusion of generative AI and minimalist design. Ive left Apple in 2022, then founded LoveFrom, a design firm. His collaboration with OpenAI was seen as a statement: AI needs a body, not just a voice.
But now, that entire narrative is on ice. The branding was central to the product’s identity. Marketing materials, leaked in January 2026, showed sleek, orb-like devices labeled “io One” and “io Loop.” The name was meant to evoke both input/output and a personal AI identity—“I/O” as in “I am AI.”
It was clever. Too clever, perhaps. Because iyO’s lawyers argued—and the court appears to have accepted—that this very cleverness increases consumer confusion. If both products are AI-forward, wearable, and named io, users won’t stop to parse legal distinctions. They’ll assume connection.
Why This Isn’t Just About a Name
This case cuts to the core of how tech builds. For years, companies have operated under the assumption that if you’re big enough, fast enough, or innovative enough, you can bend norms—including naming conventions. Google, Apple, and Meta have all faced (and often settled) trademark disputes quietly, buying their way out or rebranding in private.
But iyO didn’t settle. It fought. And won—at least for now.
The implications are chilling for product teams everywhere. No more assuming you can slap a sleek two-letter name on a device and launch globally. No more treating trademarks as afterthoughts to be cleared post-launch. This ruling signals that small companies with clean paper trails can, and will, stop giants in their tracks.
The Cost of Moving Fast and Breaking Things
OpenAI and Ive’s team likely assumed they were in the clear. After all, “io” is a common tech shorthand. It appears in domain names (.io), programming syntax, and startup branding. But legal precedent is clear: common usage doesn’t override registered trademarks in related classes.
Their mistake may have been in due diligence. USPTO records show OpenAI filed a trademark application for “.io in November 2025—four months after iyO’s was already registered and in use. That application is now suspended.
And here’s the irony: the very thing that made “io” appealing—the brevity, the tech resonance, the linguistic flexibility—is what made it legally dangerous. Short names are harder to protect, but also harder to use freely. The more distinctive, the more protected. But also, the more likely someone else already owns it.
What This Means For You
If you’re building a product, this case should keep you up at night. It’s not enough to check domain availability or social media handles. You need a full trademark clearance search before naming anything, especially if you’re entering a crowded or adjacent market. That means hiring a trademark attorney, not just running a USPTO query. iyO’s win wasn’t just about paperwork—it was about documented use in commerce, which many startups skip while iterating.
For developers, founders, and product leads: your name is not just branding. It’s a legal asset—and a liability. A name you love today could cost you millions tomorrow in rebranding, lost marketing spend, or court fees. If you’re working on AI hardware, health tech, or consumer devices, and you’re eyeing a minimalist name like “io,” “ai,” or “neon,” think again. The low-hanging names have already been picked. The era of naming-by-whim is over.
So what happens when innovation collides with bureaucracy, and the small guy wins? We’re about to find out.
