Registered Aug 11, 2026
The record shows that “CLAUDE KEEP THINKING” is a live, registered service mark owned by Anthropic, PBC, a public benefit corporation organized in Delaware. The mark is registered on the Principal Register, with the registration date of August 11 2026, and the latest status event is the confirmation of registration on that same date. The goods and services covered are extensive software‑as‑a‑service offerings that use artificial intelligence for machine learning, generative text, natural language processing, and related online non‑downloadable software. A similar name would raise the closest concern in the field of AI‑powered software services, especially those that provide online platforms for AI interaction and content generation. The record does not give the owner control over every use of the wording; it is limited to the specific services listed. No enforcement actions, oppositions, or cancellations appear in the supplied history. For someone considering a similar name, the presence of this active registration in AI software services suggests a meaningful risk of conflict in that area.

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.
