The Board dismissed this opposition to registration of
DENTISTRY DONE DIFFERENTLY for "dentist
services" because Opposer Timber Dental failed to prove
priority. Opposer claimed common law rights in the same phrase, but
its proofs showed prior use of a different mark. Timber Dental LLC v. Tooth, LLC,
Opposition No. 91234587 (April 12, 2019) [not precedential]
(Opinion by Judge Lorelei Ritchie).

In order to establish prior trademark rights, an opposer must
show that its alleged mark is distinctive, inherently or otherwise.
There was no allegation or evidence that DENTISTRY DONE DIFFERENTLY
is not distinctive of "dental services," and so the
Board found that "that while the mark is suggestive, on this
record it appears to be inherently distinctive."
