The ‘io’ Trademark Dispute That Derailed OpenAI’s AI Hardware Launch — What It Reveals About IP Strategy for Tech Giants Entering Hardware

OpenAI’s AI hardware device, developed in collaboration with designer Jony Ive, was confirmed in February 2026 to have been delayed to 2027 or later, with the “io” product name also abandoned. According to 9to5Mac’s report from February 10, 2026, the delay was driven by two overlapping factors: technical development challenges and a trademark dispute. The case has drawn significant attention as a study in the trademark preemption risks AI companies face when entering the hardware market.

The Trademark Dispute Over “io”: How It Unfolded

The conflict began in May 2025. OpenAI acquired IO Products, Inc. — a company co-founded by Jony Ive’s design studio LoveFrom — for approximately $6.5 billion, and announced the development and launch of an AI device under the “IO” brand.

In response, iyO, Inc., a startup developing AI-powered hearing assistance devices, filed a trademark infringement lawsuit in the U.S. District Court for the Northern District of California in June 2025. iyO had filed its trademark in September 2021 and completed registration in 2024. The registered mark covered product categories including audio headphones, computers, and software integrating data through interactive audio systems — a direct overlap with the product category OpenAI was entering.

iyO’s legal theory was based on reverse confusion — the doctrine that a more prominent junior user (OpenAI) can overwhelm an established senior user (iyO), causing consumers to believe the senior user’s brand belongs to the larger company. The marks differ by only a single letter (IO vs. IYO), and both are pronounced identically (“eye-oh”), a fact the court acknowledged.

The Legal Proceedings: From District Court to the Ninth Circuit

U.S. District Judge Trina Thompson found iyO’s claims sufficiently meritorious to issue a temporary restraining order (TRO) prohibiting OpenAI’s use of the “IO” mark and any confusingly similar marks in connection with competing products.

OpenAI appealed, but the U.S. Court of Appeals for the Ninth Circuit affirmed the TRO in a December 4, 2025 ruling. The three-judge panel led by Circuit Judge S.R. Thomas applied the AMF v. Sleekcraft Boats likelihood-of-confusion framework and weighted two factors as decisive: the similarity of the marks (single-letter difference, identical pronunciation) and the relatedness of the goods (both companies developing competing AI devices). Notably, the court held that trademark infringement does not require an actual sale — OpenAI’s May 2025 announcement alone was sufficient to trigger the injunction.

In March 2026, iyO amended its complaint to add allegations of trade secret misappropriation, escalating the dispute significantly. The amended claims allege that a former iyO engineer downloaded confidential files and transferred them to a co-founder of IO Products.

OpenAI’s Response and the Impact on Product Launch

Jony Ive’s spokesperson had initially called iyO’s complaint “utterly baseless” and pledged to “fight it vigorously.” Following the Ninth Circuit’s decision, however, the company reversed course.

In court filings, OpenAI VP and General Manager Peter Welinder confirmed the company had “decided not to use the name ‘io’ (or ‘IYO,’ or any capitalization of either).” The replacement product name has not been disclosed.

On launch timing, the combination of technical challenges (a prototype reportedly existed as of November 2025) and the trademark dispute pushed the device’s release from an original 2026 target to February 2027 or later, per information disclosed through court documents. OpenAI has hired additional Apple alumni to continue development.

IP Risk Analysis: Trademark Preemption When AI Companies Enter Hardware

Several intellectual property lessons emerge from this case.

First, the case demonstrates the critical importance of comprehensive trademark clearance before any product announcement. Despite executing a $6.5 billion acquisition and launching a product brand simultaneously, OpenAI apparently failed to identify — or chose to discount — an identically pronounced registered mark in a directly competing product category. The case illustrates that clearance searches must extend to phonetic equivalents, not just visual or spelling-based similarity.

Second, there is a structural asymmetry in trademark risk when software companies enter hardware markets. OpenAI commands extraordinary recognition in the AI and software domain, but is a new entrant in the consumer audio and computing device category — where startup iyO held senior rights. As the convergence of AI technology and physical products accelerates, collisions with the existing trademark portfolios of established consumer electronics companies and startups are likely to increase.

Third, as analysis of OpenAI’s patent strategy shows, the company’s patent portfolio surged in 2023 and is concentrated in software technologies — image generation (U.S. Patent No. 11,922,550), speech recognition (No. 12,079,587), and LLM interaction (No. 12,051,205). Patent protection for physical device manufacturing and distribution has lagged, and trademark protection followed a similar pattern of playing catch-up.

Fourth, the case reaffirms the practical effectiveness of the reverse confusion doctrine. The doctrine serves an important protective function when large companies risk overwhelming smaller senior users. The ability of a startup to enforce trademark rights against a global AI company demonstrates that trademark law continues to provide meaningful protection for smaller innovators.

What to Watch Going Forward

The newly added trade secret allegations considerably expand the complexity and potential financial exposure of the litigation. If the former employee’s conduct is proven, damages could increase substantially. The name OpenAI selects for its hardware device will itself be closely watched as a test of how thoroughly the company conducts its next round of trademark clearance.

With many players targeting the AI hardware market, collisions over phonetically similar or visually close trademarks are likely to multiply. For both AI companies and startups developing hardware, the priority placed on building trademark portfolios before hardware launches has never been higher.
