SEA

What this record means

The record shows the mark SEA was cancelled, so it is not a live registration; the last owner listed is RICHARD HIRSCHMANN GMBH & CO., a German limited partnership, and the cancellation was entered on Sep 15 2007 because the registrant failed to file a required Section 8 declaration. The registration covered Class 009 electrical and electronic devices for controlling scalable signal and data transmission networks—specifically switches, routers, hubs, and network interface cards—and Class 042 technical advice for those same devices, so a similar name used in networking hardware or related consulting would raise the closest record‑based concern. The record does not give the owner control over every possible use of the word “SEA,” only over the listed goods and services. No Supplemental Register entry appears, and the prosecution history simply tracks the normal examination, publication, registration and later cancellation steps. The supplied history shows no oppositions, cancellations beyond the Section 8 lapse, or other enforcement actions. I'd treat this as a moderate concern if you plan to use “SEA” for networking equipment or related tech services.
