What this record means
The record shows that PORTQUEST is an abandoned service‑mark application, filed by Graphic Details Inc., a corporation organized in New Hampshire, and the USPTO marked it dead on April 2 2019 after the applicant failed to respond to an Office action. The only goods and services listed are “Educational and entertainment services, namely, a continuing program about the navigation of Portsmouth, NH accessible by means of a mobile application” in International Class 041. A similar name used for anything outside that narrow educational‑app context would be farther from the scope shown here, and the record does not give the owner control over every use of the word PORTQUEST. The prosecution history notes a non‑final action in September 2018 and the abandonment notice in April 2019, which is the latest meaningful status event; no enforcement actions appear in the file. I'd treat this as a modest concern if your product or service is also an app‑based guide to Portsmouth, NH, but the risk drops sharply for unrelated offerings.
