What this record means
The record shows that ECOONE is a live, Principal Register registration owned by Ecochlor, Inc., a Delaware corporation, and it was officially registered on May 31 2022 after a notice of registration confirmation was emailed that same day. The protection is limited to “ship ballast water treatment system comprised of chlorine dioxide generator, control apparatus, and chemical tanks” filed in International Class 011, with a first use date of November 18 2021. A similar name used for anything outside that narrow marine‑treatment equipment context would be the closest record‑based concern, but the record does not give Ecochlor control over every possible use of the word ECOONE in other industries. The prosecution history shows a standard path to registration—filing, publication, a statement of use, an extension, and final allowance—without any Supplemental Register involvement. The supplied history contains no oppositions, cancellations or other enforcement actions. I'd treat this as a meaningful concern if you plan a name for comparable marine‑treatment products, but the risk drops sharply for unrelated goods or services.
