What’s Trending In Trademarks // March 2026

Why It Matters

These rulings tighten brand‑name safeguards and limit AI‑generated content ownership, forcing companies to adapt naming, filing, and content‑policy strategies to avoid costly litigation and delays.

Key Takeaways

• OpenAI barred from using “Cameo” for Sora feature.
• Supreme Court left AI copyright requiring human authorship unchanged.
• Third Circuit to resolve split on merchandise trademark infringement.
• USPTO staffing freeze may lengthen trademark processing times.
• Early trademark filing crucial amid legal and agency uncertainty.

Pulse Analysis

The OpenAI injunction illustrates how a seemingly innocuous feature name can trigger immediate legal action. Courts are treating descriptive terms like “Cameo” as suggestive when they clash with established brands, allowing swift preliminary injunctions that force rapid rebranding. Companies developing AI‑driven products must embed trademark searches into the early stages of naming, treating clearance as a core component of product development rather than an afterthought. This proactive approach reduces the risk of costly injunctions that can stall launches and damage reputations.

At the same time, the Supreme Court’s refusal to hear Thaler v. Perlmutter cements the principle that copyright protection hinges on human creative input. AI systems that autonomously generate art, music, or text remain outside the scope of traditional copyright, leaving firms without clear ownership rights. In‑house counsel should therefore audit AI‑assisted workflows, document human contributions, and consider alternative protection mechanisms such as trade secrets or contractual licenses. Understanding the threshold for human authorship helps organizations avoid false expectations about exclusive rights and mitigates exposure to infringement claims.

The broader trademark landscape is further complicated by the USPTO’s hiring freeze and the pending Third Circuit decision on university‑licensed merchandise. Reduced examiner capacity could reverse recent gains in filing speed, making early submission more critical than ever. Simultaneously, the appellate split over the “per se” rule signals that courts may soon redefine infringement standards for unlicensed merchandise. Brands should monitor the Third Circuit’s ruling, adjust enforcement strategies, and build extra runway into launch timelines to accommodate potential delays in registration and litigation outcomes.
