When you dont own the IP, the trademark infraction becomes moot when the product is different than the trademark (Diabecline vs Vitastem)
confusion with 2 names entirely different from one another. Also hard to confuse one product (Diabecline) that was discontinued because of product failure, and one that works and ascending (Vitastem). A cynical person might think the trademark owner of the failed product is trying to interfere in the sales and ownership of the working and ascending product. With no IP ownership of anything involved here. Kind of like a poster here suing Chris on infringement, with as much IP as the said trademark owner.
