Owner: AUTO AIR EXPORT, INC.
Class 004 -
Filed Nov 02, 1999
Registered Oct 16, 2001
The record shows that “MASTERCHEM” is a live, registered mark on the Principal Register, owned by AUTO AIR EXPORT, INC., a Texas corporation. The mark covers chemical lubricants for air conditioning systems, first used in commerce on February 11, 1998. A similar name would raise the closest concern for products or services that involve chemical lubricants for air‑conditioning or related HVAC applications. The record does not give the mark owner control over every use of the word “Masterchem” in all contexts. The most recent maintenance event is the renewal on May 29, 2021, which keeps the registration active. No opposition, cancellation, or court action appears in the supplied history, so the record shows no visible enforcement activity. For someone considering a similar name, the primary risk lies in the chemical lubricant and HVAC space; outside that niche the concern is less direct.

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.
