ROT PRUF COPPERSerial 71622330 · Supplemental Register
Dead · Expired
Owner: FUTURITY THREAD COMPANY
Class 023 -
Filed Dec 11, 1951
Registered Jun 02, 1953
The record shows that ROT PRUF COPPER is a dead Supplemental Register registration owned by FUTURITY THREAD COMPANY, a corporation organized in Massachusetts, and it expired because it was not renewed, with the last status change recorded on March 7 1994. The registration covered class 023 goods described as “thread, including welt thread, McKay thread, shuttle thread, lockstitch thread and patching thread, all containing copper salts.” A similar name used on any copper‑salt‑containing thread would be the closest area of concern, while uses on unrelated products would fall farther from the scope shown here. The prosecution history indicates the mark was initially refused on a descriptiveness ground, then amended and allowed onto the Supplemental Register in June 1953, and later renewed once before lapsing. No oppositions, cancellations or court actions appear in the supplied history, so there are no visible enforcement signals. I'd treat this as a meaningful concern if you plan a name for copper‑based thread products, but it does not control all other uses of the words.
Full event history, owner details, and verdict inside.
The way I'd use it, honestly, is as the thing you attach when a bank, a marketplace, or a co-founder asks "are we clear on the name". It answers in one page.
