What this record means
The record shows that ROT‑STOP is a dead Supplemental Register registration owned by VALSPAR CORPORATION, THE, and it expired when the required renewal was not filed, with the status date of March 21 2009 marking the cancellation. The registration covered only one class – Class 001 – for “liquid preservative for wood, canvas, and rope, to prevent rot, mildew, or decay,” so a similar name used on those kinds of wood‑preserving chemicals would be the closest area of concern. Because the mark sits on the Supplemental Register, the prosecution history indicates it was initially registered on June 15 1948 and later renewed, but the record does not show a principal‑register grant or a refusal for descriptiveness; it simply reflects the supplemental status without implying broader protection. The latest meaningful event is the 2009 cancellation, and no oppositions, cancellations, or court actions appear in the history. I'd treat this as a modest concern if you plan to market a wood‑preserving product under a similar name.
