OPENAI O1
Serial 98873803 · Principal Register
Dead · Refused

Owner: OpenAI, Inc.
Class 009 - Electrical & Scientific Apparatus
Class 042 - Scientific & Technology Services
Filed Nov 26, 2024

The record shows that the mark “OPENAI O1” is dead, having been abandoned because the applicant did not respond to an Office action. The owner listed is OpenAI, Inc., a Delaware corporation. The mark was filed on November 26, 2024 under an intent‑to‑use basis for a wide range of downloadable computer software development tools and online non‑downloadable software services related to natural language processing, voice and speech recognition, image and video generation, and machine‑learning based analysis. A similar name would raise the closest concern in the same technology and software services areas, especially where the goods or services involve machine‑learning tools or online software platforms. The record does not give the owner control over every use of the wording; it only covers the specific goods and services listed. The prosecution history shows a non‑final action in June 2025 and an abandonment notice on October 1, 2025, with no enforcement actions recorded. For someone considering a similar name, the abandoned status reduces the risk of direct conflict, but the overlapping technology scope still warrants caution.

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.

Your name deserves a straight answer.
