What this record means
The record shows that the “JACK” mark, owned by Jubert, Inc., a California corporation, was registered on the Principal Register for clothing (class 025 – belts, bottoms, jackets and tops) but was cancelled on Dec 17 2021 because the owner failed to file an acceptable Section 8 declaration, so the registration is now dead. The goods listed are limited to apparel, so a similar name used on clothing would raise the closest record‑based concern, while uses in unrelated categories would be farther from the scope shown here. The record does not give Jubert, Inc. control over every use of the word “JACK” in any context. The latest meaningful event is the cancellation notice on Dec 17 2021; no further maintenance or renewal dates are provided. The prosecution history contains only routine filing and renewal reminders and shows no oppositions, cancellations beyond the Section 8 lapse, or court actions, so the supplied history shows no visible enforcement activity. I'd treat this as a moderate concern if you plan a clothing brand with the same name.
