What this record means
The record shows that the mark GMA was registered on the Principal Register to GMA, INC., a Colorado corporation, for jewelry (class 014) with a first use date of March 1988, but the registration was cancelled on October 26 1998 because the registrant failed to file an acceptable Section 8 declaration, so the mark is now dead and not live. The listed goods are limited to jewelry, so a similar name used for that same category would present the closest record‑based concern, while uses in unrelated fields would be farther from the scope shown here. The record does not give the owner control over every possible use of the letters “GMA.” No Supplemental Register filing appears, and the prosecution history simply moves from examiner amendment to registration and then to the Section 8 cancellation. The supplied history contains no oppositions, cancellations beyond the Section 8 event, or other enforcement activity. I'd treat this as a meaningful concern if you plan a jewelry brand with the same name, but the risk drops for other product types.
