PURQUEST
Serial 97146504 · Principal Register
Dead · Refused

Owner: PurMinds Neuropharma Inc.
Class 041 - Education & Entertainment
Class 042 - Scientific & Technology Services
Filed Nov 29, 2021

The record shows that PURQUEST is an abandoned application – the USPTO marked it “dead” after no Statement of Use was filed, with the abandonment notice and final abandonment both dated Oct 9 2025, and the owner listed as PurMinds Neuropharma Inc., a Canadian corporation. The filing covered two classes: 041 (education and entertainment) for “provision of libraries in the nature of databases featuring compounds, molecules and formulations for treatment and prevention in the field of psychiatric and neurological disorders, neurodegenerative diseases, and Alzheimer’s disease,” and 042 (scientific and technology services) for “provision of databases featuring compounds, molecules and formulations for scientific research and drug discovery in the same fields.” A similar name would raise the closest record‑based concern if used for comparable scientific‑research or medical‑database services, but the record does not give the owner control over every use of the word “PURQUEST” in other areas. The prosecution history shows the application moved from a notice of allowance in February 2023 to a series of extensions for filing a Statement of Use, ultimately ending in abandonment when no use statement was submitted. No oppositions, cancellations, or court actions appear in the supplied history. I'd treat this as a meaningful concern if you plan a database or research service in those medical fields, but the risk is far lower for unrelated goods or services.
