WINDSURF
Live · Registered LIVE/REGISTRATION/Issued and Active
What this record means
The record shows that the mark “WINDSURF” is live and registered on the Principal Register under serial 98311495, owned by Exafunction, Inc., a Delaware corporation. The registration covers services in class 042, specifically providing temporary use of non‑downloadable computer software, SDKs, APIs, and AI‑based tools for software development and generative modeling, first used in commerce on November 12, 2024. A similar name would raise the closest concern for software‑development services that involve AI or deep learning technology, while unrelated goods or services would be farther from the scope shown. The record does not grant control over every use of the word “WINDSURF.” The latest maintenance event was the Notice of Registration Confirmation emailed on June 16, 2026, and the next significant date is the registration date itself, June 16, 2026. No enforcement actions such as oppositions or cancellations appear in the supplied history. For someone considering a similar name, the risk is that using “WINDSURF” for AI‑related software services could be viewed as infringing this active registration.
