WWE filed several trademarks this week, including one that could indicate that a Superstar will be losing his last name.
According to USPO's public database, a trademark for "Dominick" was filed on 10/13/20 for the following:
"IC 041. US 100 101 107. G & S: Entertainment services, namely, wrestling exhibitions and performances by a professional wrestler and entertainer rendered live and through broadcast media including television and radio, and via the internet or commercial online service; providing wrestling news and information via a global computer network; providing information in the fields of sports and entertainment via an online community portal; providing a website in the field of sports entertainment information; fan club services, namely, organizing sporting events in the field of wrestling for wrestling fan club members; organizing social entertainment events for entertainment purposes for wrestling fan club members; providing online newsletters in the fields of sports entertainment; online journals, namely blogs, in the field of sports entertainment"
WWE also filed trademarks for the following NXT UK talent on 10/13/20: Levi Muir, Kenny Williams, Joseph Conners, Johnny Saint and Jinny.
The "Dominick" filing could mean that WWE plans on having Dominik Mysterio drop his last name, along with a slight alteration to the spelling of his first name. This would follow a long list of wrestlers that have lost their last name simply because Vince McMahon felt it was better for them to have one name. The change to his first name would be for merchandising reasons.
Rey Mysterio trademarked the name Principe Mysterio for Dominik in 2019 in hopes of having his son wear a mask and there have been talks about Dominik wearing a mask at some point but that doesn't appear to be in the immediate plans.
Wrestlers that have lost their first or last names over the years include Apollo Crews (he lost his last name and got it back), Charlotte Flair (she lost her last name and got it back), Alexander Rusev, Big E Langston, Elias Sampson, and Antonio Cesaro, just to name a few.
