What this record means
The record shows that the mark “CLAUDE” is live and registered on the Principal Register, owned by Anthropic, PBC, a public benefit corporation organized in Delaware. The registration was filed March 4 2024 and became effective October 7 2025. The goods and services listed are scientific and technology services, specifically providing temporary use of online, non‑downloadable software that includes an artificial intelligence model for generative text and natural language processing tasks, as well as an application service provider featuring an API for these functions and software‑as‑a‑service offerings. A similar name used in the same or closely related AI‑software services would raise the closest record‑based concern. This record does not give the owner control over every use of the word “CLAUDE.” No enforcement activity such as oppositions or cancellations appears in the supplied history. The next significant event would be the maintenance filing due in 2029, but that date is not provided here. If you are thinking of using a similar name in AI‑software services, this record suggests a meaningful risk of conflict.
