What this record means
The record shows the mark JACK is abandoned, with the last status dated March 2 2021, and the owner listed as Marcia Elizabeth Skrmetta, an individual. The application covered Class 045 legal and personal services, specifically “Cartoon character licensing; licensing of advertising slogans and cartoon characters,” so a similar name used in any cartoon‑character or slogan‑licensing business would be the closest area of concern. The record does not give the owner control over every other use of the word JACK, especially in unrelated fields. Because the filing was on an intent‑to‑use basis and the prosecution history ends with an abandonment notice for failure to respond to a non‑final office action, there was no registration on either the Principal or Supplemental Register. The latest meaningful event is the abandonment notice on March 2 2021, and no enforcement actions appear in the file. I'd treat this as a meaningful concern if you plan a similar licensing service, but the risk is limited to the narrow cartoon‑character licensing scope shown.
