Presently Markify does not search among dead trademarks. This is because dead trademarks, with some rare exceptions (i.e. the mark is still in use, but the registration has not been extended for some reason), generally don't have any protection.

Markify is a name-screening tool and there is no guarantee that it will find all potentially conflicting trademark registrations or that the found "similar" trademarks will pose a problem in the naming matter at hand.
