IN-V-TRON

What this record means

The record shows that IN‑V‑TRON is a dead Principal Register registration owned by NUCLEAR SYSTEMS, INC., a Delaware corporation, and it expired because the registration was not renewed, with the last status change recorded on Nov 04 1992. The registration covered a very specific laboratory radiation monitoring instrument – a single‑channel analyzer with integrated circuits, scintillation detector, amplifier, electronic timer, high‑speed scaler and ultra‑stable high‑voltage power supply for detecting, analyzing and counting gamma rays – filed in class 009. A similar name used for anything outside that narrow scientific apparatus field would be the closest record‑based concern, but the record does not give the owner control over every use of the wording in other contexts. The prosecution history shows the mark was accepted for registration on May 09 1977 and later expired under Section 9, with no later maintenance filings. The supplied history contains no visible enforcement actions such as oppositions or cancellations. I'd treat this as a modest concern if you plan a name for scientific or radiation‑monitoring equipment, but the risk drops sharply for unrelated goods or services.
