The record shows that “SEA” is a live, Principal Register trademark owned by Birchtech Corp., a Delaware corporation, and it was registered on June 23 2026 after filing on November 20 2025. The registration covers three classes: Class 001 for chemicals used to purify water and remove contaminants, including mercury‑capture agents for industrial and power‑generation settings; Class 040 for services and technologies that clean water and air through environmental remediation; and Class 042 for environmental‑science consulting, engineering, testing, inspection and compliance services. A similar name used in any of those water‑ or air‑related chemical or environmental service contexts would be the closest record‑based concern, while uses outside those areas are farther from the scope shown. The record does not give Birchtech control over every possible use of the word “SEA.” The latest meaningful event is the notice of registration confirming its Principal Register status on June 23 2026, and the history contains no oppositions, cancellations or other enforcement actions. I'd treat this as a meaningful concern if you plan a name in the same environmental‑water or air remediation space.
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.
