CHATGPUSerial 98526452 · Supplemental Register
Dead · Refused
Owner: Inference.ai
Class 042 - Scientific & Technology Services
Filed Apr 30, 2024
The record shows that the mark CHATGPU is abandoned, with the last status change on Aug 22, 2025 when the USPTO issued an abandonment notice because the applicant failed to respond to a final refusal. The owner listed is Inference.ai, a California limited‑liability company, and the application was for a service mark in International Class 042 covering “Software as a Service (SAAS) featuring software for use as a digital assistant that provides recommendations for data‑center GPUs …” – essentially a cloud‑based tool that helps users pick graphics‑processing units. Because the filing was on the Supplemental Register, the prosecution history shows a final refusal in May 2025 followed by a petition to revive that was granted, but the applicant still did not answer the subsequent office action, leading to abandonment. No opposition, cancellation or court activity appears in the history, so there are no visible enforcement signals. While this record limits concern to SaaS GPU‑recommendation services, it does not give the owner control over every use of the word “CHATGPU.” I'd treat this as a meaningful concern if you plan a similar cloud‑based AI assistant service.
Full event history, owner details, and verdict inside.
The way I'd use it, honestly, is as the thing you attach when a bank, a marketplace, or a co-founder asks "are we clear on the name". It answers in one page.
