CORKBOSS U.S. Trademark Registration 6420422
A Trademark should uniquely identify your product or service to the public. To do so, be sure NOT to use words that your competitors use, especially not descriptive terms such as "market" for a market. You can though use such a term by blending the term with an unrelated word, BUT you won't get registration if another company registers the word in a related product or service. You need more than a search for the word.
Fortunately, Trademark and Patent Attorney Gerald R. Prettyman helped the CorkBoss team overcome those hurdles, and secured Trademark Registration for the CORKBOSS patented device. See https://www.gotabrightidea.com/post/corkboss
