The swift advancement of technology and hardware has introduced new complexities for brands competing for market dominance. A recent judicial decision illustrates how even nascent startups can encounter legal obstacles when their trademarks risk misleading consumers. The case between iyO, Inc. and IO Products, Inc. underscores the necessity of proactive trademark vigilance and the ramifications of brand resemblance in highly competitive markets.
The conflict emerged when IO Products, a hardware startup acquired by OpenAI in 2025, began promoting a next-generation computing device under the name “IO.” iyO, Inc., a competitor with a registered trademark “IYO,” contended that the marks were nearly indistinguishable and targeted the same audience. Although IO Products had not yet launched a commercial product, a court issued an injunction prohibiting its use of the “IO” mark in marketing or sales related to iyO’s offerings.
The court’s ruling highlighted that trademark disputes can escalate rapidly, even before a product reaches the market. The Ninth Circuit dismissed IO Products’ claim that the case was premature, noting the company was already developing a prototype intended to compete with iyO’s AI-focused device. Evidence indicated IO Products planned to use the “IO” mark in its marketing and had released a teaser video outlining its 2026 launch timeline.
The court applied the Sleekcraft framework to evaluate the likelihood of consumer confusion, concluding that “IYO” and “IO” are phonetically identical and visually similar. The products’ overlapping target markets further amplified the risk of confusion. The ruling also affirmed that early-stage companies face heightened exposure, as brand damage can undermine investor confidence and funding opportunities long before a product reaches shelves.
The injunction does not prohibit IO Products from using its name entirely but restricts its application in connection with products “sufficiently similar” to iy’s AI-based audio computer. This balanced approach reflects the judiciary’s role in safeguarding trademarks while allowing for innovation.
For enterprises, the case offers vital insights: Similar-sounding marks in tech sectors are likely to attract immediate legal scrutiny. Public product teasers, even without sales, can trigger trademark liability. Courts frequently support early injunctions to prevent brand dilution or market confusion. Comprehensive brand clearance should occur before public announcements or prototype reveals.
