What this record means
The record shows that the mark PULLOVER was registered on the Principal Register (Reg. 2170976) to Mine Safety Appliances Company, a Pennsylvania corporation, but it was cancelled on Oct. 29, 2021 because the owner failed to file an acceptable Section 8 declaration, so the registration is no longer live. The registration covered “full body safety harnesses not for vehicle or sports purposes” in International Class 009, meaning the closest area of concern is any product that is a safety harness of the type described; a similar name used for unrelated goods such as clothing, software or food would be farther from the scope shown here. The record does not give the owner control over every use of the word “pullover” in any context. The latest meaningful event is the Section 8 cancellation in October 2021; no further maintenance or renewal dates are listed. The prosecution history contains no oppositions, cancellations beyond the Section 8 issue, or other enforcement actions, so the supplied history shows none. I'd treat this as a moderate concern if you plan a safety‑harness product under a similar name, but the risk is low for unrelated goods.
