What this record means
The record shows that “ROT STOPPER” is a live, registered trademark owned by Hillside Roofing & Gutters, Inc., a Washington corporation, and it sits on the Supplemental Register (registration number 8299369). The registration covers metal gutter pipes (International Class 006) with a first‑use date of November 1, 2025, so a similar name used for roofing or gutter hardware would be the closest area of concern. The record does not give the owner control over every possible use of the words “rot stopper” in unrelated fields. The prosecution history indicates the application was filed on July 8, 2025, received a non‑final office action in January 2026, was amended for use, and was ultimately approved and entered on the Supplemental Register on June 9, 2026. The latest meaningful event is the notice of registration confirmation emailed on that same date. No oppositions, cancellations or other enforcement actions appear in the supplied history. I'd treat this as a meaningful concern if you plan to market gutter‑related metal products under a similar name.
