HIGH VOLTAGE VLF HIPOT

What this record means

The record shows that “HIGH VOLTAGE VLF HIPOT” is cancelled; the registration was cancelled on Oct 29 2021 because the owner, HIGH VOLTAGE, INC., did not file an acceptable Section 8 declaration, and the mark is listed as dead on the Supplemental Register. The registration covered Class 009 electrical and scientific apparatus, specifically dielectric‑strength and insulation‑resistance testing instruments such as very‑low‑frequency AC testers, portable kilovoltmeters, megonmeters and related testers for cables, transformers, switchgear, rubber goods and safety equipment. A similar name used for testing or measurement equipment in this technical field would raise the closest record‑based concern, while uses in unrelated categories would be farther from the scope shown. The prosecution history shows an initial refusal in 1998, an amendment and approval for Supplemental Register registration in 1999, and subsequent renewals until the 2021 cancellation; this sequence reflects the mark’s path to Supplemental Register status but does not imply broader protection. The supplied history contains no oppositions, cancellations by third parties or other enforcement actions. I'd treat this as a meaningful concern if you plan a name for comparable testing instruments.
