XCELL

What this record means

The record shows that XCELL is no longer active – the registration (Principal Register No. 3801705) was cancelled under Section 18 by the TTAB on August 29, 2013, and the owner listed is XCell‑Center GmbH im Institut für Regenerative Medizin GmbH. The cancelled registration covered “cells and stem cells for scientific research use” in International Class 001 and “cells and stem cells for medical use” in Class 005, so a similar name used in those biotech or medical contexts would raise the closest record‑based concern. The record does not give the owner control over every possible use of the word “XCELL” outside those specific goods and services. Because the mark was on the Principal Register, there is no Supplemental Register sequence to note. The most recent meaningful event is the cancellation grant on August 29, 2013, and the history shows no oppositions, cancellations, or court actions, so no enforcement signal appears. I'd treat this as a moderate concern if you plan to use a similar name in stem‑cell research or medical applications.
