Adobe certainly owns the copyright for the TIFF specification. I don't see a trademark registration for "TIFF" (whereas I do find one for "Photoshop" and "Adobe Photoshop") at http://tmsearch.uspto.gov/. Given that Adobe products do have trademark registrations and "TIFF" does not seems to imply that Adobe does not claim a trademark on it.

Copyright and trademark are two different things.

What data can you provide which exhibits that we need to be careful about how we use the term "TIFF"?
