CARL ZEISSSerial 71657816 · Principal Register
Dead · Expired
Owner: ZEISS, CARL
Class 009 - Electrical & Scientific Apparatus
Filed Dec 10, 1953
Registered Oct 05, 1971
The record shows that “CARL ZEISS” was a Principal Register trademark owned by ZEISS, CARL, a corporation organized in Germany, but it is now dead and expired because the registration was not renewed, with the last status change recorded on Oct 5 1992. The registration covered a very specific set of scientific and optical equipment in International Class 009, including microscopes, telescopes, photographic objectives, spectrometers, interferometers, cameras, projectors, photometric devices and related accessories. A similar name used for products in that same scientific‑instrument field would raise the closest record‑based concern, while uses outside those categories would be farther from the scope shown here. The record does not give the owner control over every possible use of the words “CARL ZEISS.” There is no prosecution history indicating any refusals or amendments, and the supplied history contains no oppositions, cancellations or other enforcement actions. I'd treat this as a meaningful concern if you plan to market optical or measurement devices under a similar name.
Full event history, owner details, and verdict inside.
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.
