XCELLSerial 73411114 · Principal Register
Dead · Cancelled
Owner: Diagnostic Technology Inc.
Class 001 -
Filed Jan 27, 1983
Registered Jun 05, 1984
The record shows that the mark “XCELL” is no longer active; it was cancelled on March 12 2005 because the registrant, Diagnostic Technology Inc., did not file a required Section 8 declaration. The mark was originally registered on June 5 1984 for the specific goods “Monoclonal Prostatic Acid Phosphatase Tissue Culture Supernatant for Hematological Investigative Use.” Because the cancellation was due to a failure to maintain the registration, the mark does not currently grant any rights, but the historical filing still indicates that the owner once claimed protection for that narrow biomedical product. A new use of the name in a closely related field—such as other diagnostic or laboratory reagents—would raise the closest concern, while uses in unrelated industries would be farther from the scope shown. The record contains no evidence of opposition, cancellation after publication, or other enforcement activity, so the supplied history shows no visible enforcement signals. For someone thinking of a similar name, the record suggests that while the mark is dead, the specific product area remains a potential point of caution.

The way I'd use it, honestly, is as the thing you attach when a bank, a marketplace, or a co-founder asks "are we clear on the name". It answers in one page.
