What this record means
The record shows that the “SEA” mark, filed by Under Sea Industries, Inc. on March 22 1979, is dead and listed as abandoned on May 16 1988, with no later activity; the owner is a Delaware corporation. The only listed coverage is a collective mark in International Class 200, described simply as “COLLECTIVE MARK” with a first use date of April 6 1976, so a similar name would raise the closest concern only if used as a collective identifier for members of an organization rather than for ordinary product or service branding. The record does not give the owner control over every use of the word “SEA.” The prosecution history shows a non‑final action mailed in July 1979, another in April 1980, and a final non‑final action in May 1988, after which the application was abandoned; no enforcement actions appear in the file. I'd treat this as a modest concern if you plan a collective‑type mark, but the risk is limited to that narrow area.
