Are Fingerworks products essential public domain now?

[og_ts_user]

From my understanding of trademark law, the Fingerworks brand and logo are unprotected now because they aren't used in the marketplace. Also from my understanding of patent law, any patents required to make any Fingerworks products must have expired by now because they are older than the patent term. If someone wanted to reverse engineer the hardware and rewrite the software they could sell identical products and even use the same marketing, is that mostly true?
