I was wondering if the same logo can be used twice if registered by the same person. For example, if I were to own a company selling sports equipment called "Lightning Sports," but later on I wanted to open up a skating rink with a similar logo that is themed off of the original company, now just called "Lightning Rink." The trademarks are thus similar but not exactly the same, and they are in different contexts. Could you potentially infringe upon your own trademark? Would you simply have to let both enterprises belong to same company without changing the logo at all?
