What this record means
The record shows that the CARL ZEISS T* mark, owned by CARL ZEISS AG, is cancelled – the registration was terminated on March 25 2016 because the owner did not file an acceptable Section 8 declaration, and the record is listed as “Dead · Cancelled.” It was limited to Class 009 “Electrical & Scientific Apparatus” with the specific goods described as “Photographic Objectives,” so the closest area of concern would be any other brand using a similar name for camera lenses or related optical equipment. The record does not give the owner control over every possible use of the words “CARL ZEISS T*” in unrelated fields. This was a Principal Register registration, not a Supplemental Register entry, and the prosecution history simply tracks the normal filing, publication, registration and renewal steps before the eventual cancellation. The supplied history contains no oppositions, cancellations by third parties, or other enforcement actions. I'd treat this as a meaningful concern if you plan a name that overlaps the photographic‑objective market.
