What this record means
The record shows that ROT‑NOT is no longer active – it was cancelled on Jan 15 2016 because the registrant, Industrial Energy Products, Inc., did not file an acceptable Section 8 declaration, so the registration is dead. The only goods listed are “thermal protective coating for the prevention of corrosion of industrial boiler and furnace surfaces” in International Class 2, meaning a similar mark would raise the closest record‑based concern if you’re offering any kind of anti‑corrosion coating for boilers or furnaces. The record does not give the owner control over every use of the word “ROT‑NOT” in unrelated fields. This was a Principal Register registration, not a Supplemental Register filing, and the prosecution history simply tracks the normal filing, publication, registration and renewal steps before the eventual cancellation. 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 to market a similar protective coating, but the risk is far lower for unrelated products.
