Class 004 -

Registered Oct 16, 2001
The record shows that the mark “MASTERCHEM” is live and registered on the Principal Register under serial 75838940, owned by AUTO AIR EXPORT, INC., a Texas corporation. The registration covers chemical lubricants for air conditioning systems, first used on February 11, 1998. A similar name would raise the closest concern for businesses dealing with chemical lubricants for HVAC or related air‑conditioning products. The record does not give the mark control over every use of the wording; it applies only to the specified goods. The most recent maintenance event was the renewal on May 29, 2021, which extended the registration for another ten years. No opposition, cancellation, or court action appears in the supplied history, so there is no visible enforcement signal. For someone considering a similar name, the risk is that use in the same or closely related chemical lubricant market could be viewed as infringing this active, renewed registration.

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.
