JACK

What this record means

The record shows a live Principal Register service mark for “JACK,” owned by SPARKNET COMMUNICATIONS LLC, a Tennessee limited‑liability company, and it covers audio broadcasting, radio broadcasting and streaming of audio materials over the Internet (International Class 038). A similar name used in any of those communication‑service contexts would create the closest record‑based concern, while uses outside that narrow scope fall farther from the listed coverage. The registration does not give the owner control over every possible use of the word “JACK.” The prosecution history shows no supplemental‑register filing, so the mark was examined and entered directly on the Principal Register. The most recent meaningful event is the first‑renewal filing and acceptance on January 13 2021, and the supplied history contains no opposition, cancellation or other enforcement activity. I’d treat this as a meaningful concern if you plan a comparable name in audio‑streaming or radio services.
