Context and Origins of the Dispute

Earlier this year, OpenAI announced its acquisition of the AI startup founded by renowned designer Jony Ive, known as iyO. Shortly after, iyO initiated legal action against OpenAI, alleging trademark infringement related to the use of the “io” brand name.

Documents released during the litigation revealed that iyO’s CEO, Jason Rugolo, had attempted to recruit Evans Hankey, then Apple’s Vice President of Industrial Design, prior to her joining Ive’s company. Additionally, it was disclosed that OpenAI’s Sam Altman and Jony Ive had agreed on the “io” name by mid-2023. Rugolo approached Altman in early 2025 seeking investment for a project focused on advancing human-computer interaction, but Altman declined, citing his work on a competing initiative. Rugolo’s response to this was notably apprehensive.

Claims and Counterclaims: The Core of the Conflict

iyO’s lawsuit contended that OpenAI was preparing to launch a product with a name and concept closely resembling iyO’s planned AI-powered in-ear headphones. OpenAI countered by clarifying that its initial product would neither be a wearable device nor an in-ear headset. Rugolo reportedly proposed that OpenAI acquire iyO for $200 million, an offer that was not accepted.

Initially, the court sided with iyO, issuing a Temporary Restraining Order (TRO) that barred OpenAI from using the “io” branding. Consequently, OpenAI removed all references to “io” from its website and marketing materials.

Recent Ruling by the 9th Circuit Court of Appeals

On Wednesday, the 9th Circuit Court of Appeals upheld the TRO, maintaining the prohibition on OpenAI’s use of the “io” brand for products that could be confused with iyO’s offerings. The court’s decision emphasized two key points:

• Potential for Consumer Confusion: The court recognized that “IO” and “iyO” are phonetically identical and that both companies aim to market AI-driven computing devices with natural language capabilities. It highlighted the risk of “reverse confusion,” where a larger, well-funded company’s product overshadows a smaller competitor’s brand, misleading consumers about the source of the products.
• Irreparable Damage: The court acknowledged that OpenAI’s aggressive product launch could jeopardize iyO’s ongoing fundraising efforts and harm its brand reputation.

Following this ruling, the case is expected to proceed to district court for a preliminary injunction hearing, which will determine whether the restrictions on OpenAI’s branding will remain or be modified.

Legal experts anticipate a protracted battle, with a preliminary injunction hearing scheduled for April 2026. The process will include extensive fact-finding, expert testimonies, dispositive motions, and potentially a jury trial extending into 2027 or 2028.

Implications for the AI Industry and Market Dynamics

This legal confrontation underscores the increasing importance of intellectual property and branding in the rapidly evolving AI sector. As companies race to develop innovative AI-powered devices, disputes over trademarks and market positioning are becoming more frequent.

For instance, the case highlights how emerging startups like iyO face significant challenges when competing against tech giants with substantial resources, such as OpenAI. The court’s recognition of “reverse confusion” reflects a growing awareness of the power imbalance in the tech industry and its impact on smaller innovators.
