What this record means
The record shows that the “JACK SPARROW” mark, owned by Disney Enterprises, Inc., was registered on the Principal Register for backpacks (International Class 018) but was cancelled on Dec 19 2014 because the registrant failed to file an acceptable Section 8 declaration, so the mark is now dead. The goods listed are limited to backpacks, so a similar name used on that same product line would raise the closest record‑based concern, while uses on unrelated goods would be farther from the scope shown here. The record does not give Disney control over every use of the words “Jack Sparrow” in all contexts. The prosecution history shows the application proceeded through examination, a statement‑of‑use filing, and ultimately registration, but the later cancellation reflects a lapse in required maintenance rather than a substantive refusal. No oppositions, cancellations beyond the Section 8 issue, or court actions appear in the supplied history. I'd treat this as a meaningful concern if you plan a backpack brand with the same name, but the risk drops for other product categories.
