G

What this record means

The record shows that the mark “G” was registered on the Principal Register in 1963 and is now dead because it was not renewed. The owner is Grason‑Stadler Company, Inc., a corporation organized in Massachusetts. The registration covered a narrow set of electrical and scientific apparatus, including audiometers, psychogalvanometers, and other psychoacoustic testing equipment. A similar name used in those specific categories would raise the closest record‑based concern. The record does not give the owner control over every use of the letter “G” in other contexts. The only maintenance event recorded is the expiration in 1987; no further actions or enforcement activity appear in the supplied history. For someone thinking of a similar name, the risk is concentrated around the listed scientific testing equipment, and there is no visible enforcement signal beyond the mark’s expiration.
