This month brought two fast-moving courtroom fights over tech brand names, a major USPTO modernization announcement, and a quietly significant celebrity trademark settlement. The throughline: brand identity disputes in the AI space are accelerating, and the legal system is still working out the rules.
OpenAI’s “io” Problem Gets Worse
The biggest trademark story this month has OpenAI at the center of it, again.
On April 15, a federal judge questioned the sincerity of OpenAI’s vow not to use the “io” name for AI-powered devices during a hearing about whether to extend an order blocking the company’s use of the name while IYO Inc.’s trademark infringement lawsuit progresses. Judge Trina L. Thompson questioned why OpenAI said it would not use “io” but then attempted to delay the April 15 hearing until January 2027, roughly one month before OpenAI says it may launch AI-powered hardware. (Bloomberg Law, Apr. 15, 2026)
The background: IYO sued after OpenAI acquired Jony Ive’s IO Products in May 2025, arguing that the IO mark was confusingly similar to its own IYO mark. Both marks are pronounced identically. Both companies are developing AI-powered devices intended to offer a new form of computing. The Ninth Circuit affirmed the district court’s temporary restraining order in December 2025, finding that the marks differ by only one letter, are pronounced identically, and that IO’s own correspondence described its product as “competitive” with IYO’s. (IPWatchdog, Dec. 4, 2025)
The court also found a risk of “reverse confusion”, the scenario in which a better-funded junior user saturates the market and causes consumers to believe the smaller senior holder is the infringer. That theory, applied to an OpenAI product launch, is exactly the kind of threat that can make a startup’s fundraising disappear overnight.
This case is a clean object lesson for in-house counsel. Before your company announces a new product, platform, or feature, particularly in the AI space where names are proliferating fast, the trademark clearance work needs to happen first. A high-profile product launch is one of the worst possible moments to discover you are someone else’s homophone.
Temu’s “We’re Just a Marketplace” Defense Falls Short
Online marketplace Temu tried to have trademark infringement claims dismissed in a lawsuit filed by the band Twenty One Pilots, arguing it cannot be held liable for infringement by third-party sellers. A court rejected that argument after Twenty One Pilots filed an amended complaint asserting that Temu functions as a direct seller with substantial control over its marketplace. The amended complaint includes claims for trademark infringement, unfair competition, misappropriation of likeness, and statutory damages of up to $2,000,000 per counterfeit mark per type of product sold. (Digital Music News, Apr. 9, 2026)
Temu has faced a wave of similar suits from artists and brand owners, and others with nearly identical facts have been dismissed. The difference here is how Twenty One Pilots’ counsel structured the amended complaint, specifically its argument that Temu is “a vertically integrated manufacturer and retailer,” not a passive intermediary. That framing kept the case alive.
The failed dismissal signals that platform operators who exercise meaningful control over product listings, fulfillment, and pricing may not be able to hide behind traditional safe harbor arguments. If your company licenses its marks and sells through online marketplaces, this case is worth watching closely.
The USPTO Deploys AI to Unclog the Application Backlog
On March 19, the USPTO announced the release of the Trademark Classification Agentic Codification Tool, or “Class ACT,” an AI agent that automatically assigns international classes, design search codes, and pseudo marks to unclassified trademark applications. What previously took up to five months can now be done in minutes. (USPTO Press Release, Mar. 19, 2026)
Although USPTO staff still review Class ACT’s work before it becomes final, the data becomes available almost immediately, benefiting both examining attorneys and applicants. The USPTO indicated that additional AI-powered trademark tools are forthcoming.
For applicants, this should mean faster examination timelines and earlier clarity on application status, particularly for marks with logos, stylized designs, or unconventional spellings that historically slowed pre-examination processing. Whether the efficiency gains survive the agency’s current staffing pressures remains to be seen. But the directional move toward AI-assisted examination is real, and it follows the USPTO’s separate fraud-cancellation efforts in 2025 that removed thousands of fraudulent registrations from the register.
Prince’s Estate and Apollonia Settle Their Trademark War
Prince’s Paisley Park Enterprises and Purple Rain co-star Apollonia (birth name Patricia Kotero) reached a confidential settlement on April 9, dismissing their lawsuit just days before a scheduled hearing. The parties agreed each side would cover its own legal fees. In a clear signal that Apollonia will continue using the name, the estate simultaneously withdrew its petition to cancel her “Apollonia 6” trademark at the USPTO. (Rolling Stone, Apr. 9, 2026)
The underlying dispute dated back years, involving dueling trademark applications over the “Apollonia” name. Apollonia argued that Prince never sought to trademark the name before his death in 2016, and it was improper for the estate to assume control of it afterward.
Ultimately, the estate dropped its cancellation petition without prejudice. For in-house counsel managing legacy brand portfolios, this case is a reminder that estate IP assets require active governance. Marks that lapse, are never filed, or are left without a clear ownership framework become disputes waiting to happen.
Bottom Line
Two words define this month: speed and clarity. Tech companies are naming products faster than they are clearing them. AI tools are accelerating the USPTO’s examination pipeline. And courts are making clear that platform operators and product launchers alike will be held to account when brand conflicts arise. If your trademark clearance process has not kept pace with your product development cycle, close that gap now.
