What this record means
The record shows the mark JACK is cancelled, having been removed from the Principal Register on July 8 2006 because the registrant failed to file an acceptable Section 8 declaration, and the owner listed is ITEMS INTERNATIONAL, INC., a Pennsylvania corporation. The registration covered only one class—025 Clothing—and was limited to “footwear, namely, snowboard boots,” so a similar name used for that specific type of footwear would present the closest record‑based concern, while uses in unrelated categories fall farther from the scope shown. The record does not give the owner control over every use of the word “JACK” in any context. No Supplemental Register filing appears, and the prosecution history simply tracks the normal examination, allowance and eventual cancellation steps. The supplied history contains no oppositions, cancellations beyond the Section 8 event, or other enforcement activity. I'd treat this as a meaningful concern if you plan to brand snowboard boots under the same name, but the risk lessens for other goods or services.
