After some further thoughts on this, I think I may have a better understanding of what is actually happening in the bigger picture here. Please, bear with me for a moment.
Vincent John Cusano became Vinnie Vincent when he officially joined KISS for the Creatures Of The Night tour, even though he wrote material and performed on recordings for the album as Vincent Cusano. I'm not aware of who it was that came up with the name, but it is known that Paul Stanley was the one who came up with the Vinnie Vincent makeup design. It is also known that Cusano would not sign the employment contract provided by KISS. It is entirely possible that the contract included other stipulations that have been undisclosed to this very day that Cusano disagreed with. I will speculate that two of those contract stipulations could have been about the ownership of the makeup design, and the Vinnie Vincent stagename, which upon signing, would have been rendered the legal intellectual property of the KISS company. In 1984, after leaving KISS, Cusano continued to use the Vinnie Vincent stagename for his future projects, and still uses the name to this day. When Ace Frehley and Peter Criss rejoined KISS in 1996 for the reunion tour, they both signed away their rights to the makeup designs, which allowed KISS full legal rights to re-use the designs on other band members should they need to do so in the event of Ace and Peter being relieved of their duties, or quitting the band. Now, Cusano has listed his trademarks of the name for sale, which would allow it to be re-used by another entity. Cusano is cashing out of the Vinnie Vincent business. This would make it possible for a new Vinnie Vincent to eventually emerge, and pretend to be him, just like Tommy Thayer and Eric Singer do with the spaceman and catman characters, however the sale of the Vinnie Vincent trademarks would allow the new owner to actually use the Vinnie Vincent name as a persona or character, whether that be a band, a comic book, a cartoon, etc. If the KISS company were to buy the trademark from Cusano, they would have the legal rights to bring that character back into the KISS canon of stage characters or comics. The only reason I could see the KISS company doing this would be to do what they did before when Vinnie Vincent was originally created, to breathe new life into the band. It would be an original KISS design, that they would legally own again. The Vinnie Vincent trademarks could also be bought up by a large music company with the resources to relaunch a Vinnie Vincent business, hiring a look-a-like to play Cusano's part. They would surely have a big task on their hands finding the right person though. The sale of the Vinnie Vincent trademarks would end Cusano's legal rights to use the name, and he would be officially retired as being the original Vinnie Vincent. If he were to release more music, or a book at some point after the sale of the trademarks, he would have to use his own name, or a different registered name.
