ELSA NEUROSCIENCESerial 98566130 · Principal Register
Dead · Refused
Owner: ELSA Neuroscience Inc.
Class 042 - Scientific & Technology Services
Filed May 23, 2024
The record shows the application for “ELSA NEUROSCIENCE” is dead – it was abandoned on March 31 2025 after the applicant failed to respond to an Office action, and the owner listed is ELSA Neuroscience Inc., a Delaware corporation. The filing covered scientific and technology services in International Class 042, specifically biochemical research and development, biotechnology research and development, neuroscience research and development, and general scientific research and development. A similar name used in those same research‑or‑development fields would raise the closest record‑based concern, while uses outside that scientific scope would be farther from the listed area. Because the mark never reached registration and sits on the Principal Register only as an abandoned application, the record does not give the owner control over every use of the words “ELSA” or “NEUROSCIENCE.” The latest meaningful event is the abandonment notice on March 31 2025, and the supplied history shows no oppositions, cancellations or other enforcement activity. I'd treat this as a moderate concern if you plan a name in the same biotech research 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.
