The record shows that the mark “WINDSURF” is live and registered on the Principal Register under serial 98976204, owned by Exafunction, Inc., a Delaware corporation. The registration covers downloadable computer software that incorporates artificial intelligence and deep learning for software development, including toolkits, SDKs, APIs, and generative model creation. A similar name would raise the closest concern in the same software‑development and AI‑tool kit area; uses in unrelated fields would be farther from the scope shown. The record does not give the owner control over every use of the word “WINDSURF.” The latest maintenance event is the registration confirmation on November 18, 2025, with no further dates listed. No oppositions, cancellations, or enforcement actions appear in the supplied history. If you plan to use a similar name in AI‑based software development, this record suggests a meaningful risk of conflict.

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.
