OpenAI and io face lawsuit over branding conflict
iyO accuses OpenAI and io of infringing its brand, but io insists the disputed device is neither wearable nor similar to iyO’s custom earbuds.

OpenAI and hardware startup io, founded by former Apple designer Jony Ive, are now embroiled in a trademark infringement lawsuit filed by iyO, a Google-backed company specialising in custom headphones.
The legal case prompted OpenAI to withdraw promotional material linked to its $6.005 billion acquisition of io, raising questions about the branding of its future AI device.
Court documents reveal that OpenAI and io had previously met with iyO representatives and tested their custom earbud product, although the tests were unsuccessful.
Despite initial contact and discussions about potential collaboration, OpenAI rejected iyO’s proposals to invest, license, or acquire the company for $200 million. The lawsuit, however, does not centre on an earbud or wearable device, according to io’s co-founders.
Io executives clarified in court that their prototype does not resemble iyO’s product and remains unfinished. It is neither wearable nor intended for sale within the following year.
OpenAI CEO Sam Altman described the joint project as an attempt to reimagine hardware interfaces. At the same time, Jony Ive expressed enthusiasm for the device’s early design, which he claims captured his imagination.
Court testimony and emails suggest io explored various technologies, including desktop, mobile, and portable designs. Internal communications also reference possible ergonomic research using 3D ear scan data.
Although the lawsuit has exposed some development details, the main product of the collaboration between OpenAI and io remains undisclosed.
