Live / Applied — Opposition pending (as of 23 Oct 2026)
What this means for you
Not registered yet, but its 30 Jul 2026 filing date beats anything filed after it. If it registers, the owner can stop confusingly similar uses in the classes it covers. An opposition to it is pending before the Trademark Trial and Appeal Board, so it will register only if the opposition fails or is withdrawn.
