KEYSTONE
Live / Registered — Registered — cancellation pending (as of 13 Jul 2026)
What this means for you
Registered since 29 Mar 2022. The owner can stop confusingly similar uses in the classes it covers; it stays on the register as long as the owner keeps up the maintenance filings (next due by 29 Mar 2028: the §8 declaration of use). A petition to cancel it is pending before the Trademark Trial and Appeal Board, so it could still be cancelled; until then it stands.
