Exact wordmark matches in the USPTO federal register, newest filing first.
What this means
The live marks span classes 1, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 16, 18, 19, 20, 21, 22, 25, 27, 28, 29, 30, 31, 32, 34, 35, 37, 38, 39, 40, 41, 42, 44, 45. A live mark in class 1 is not the same problem as one in class 45 — the risk depends on which class you sell in. The same word can often coexist in an unrelated class, but not in the same or a coordinated one.
