JACK

What this record means

The record shows that “JACK” was registered as a Principal Service Mark for DJIAN, JACQUES‑HENRI, but the registration was cancelled on Jan 17 2009 because the owner failed to file a required Section 8 declaration, so the mark is now dead. The only listed coverage is Class 036 – “providing financial guarantee and surety services,” which means the closest area of concern would be any other business offering similar financial or surety services under the name JACK. The record does not give the owner any control over unrelated goods or services, so a completely different product line would not automatically fall within this registration. The prosecution history shows the mark moved through normal examination, was allowed, and later entered the Principal Register before the cancellation; there is no indication of a Supplemental Register filing. The latest meaningful event is the Section 8 cancellation in 2009, and the supplied history shows no oppositions, cancellations beyond that, or other enforcement actions. I'd treat this as a moderate concern if you plan to use JACK in the financial‑guarantee space, but the risk is far lower for unrelated industries.
