Hey, how about all the manufactures can't use anything the others invented, ever. So Cat will have the a-arm front and slide rail rear suspensions. Polaris would have the trail arm front and boggie wheel rear suspensions. Yamaha would have the T.S.S. front and boggie wheel rear suspensions. And Doo would have the leaf spring front and boogie wheel rear suspensions.
Cat could be the only one to place the engine before the track while everyone else would have to place the engine over the track. Doo would have the only rubber track. Polaris gets to exclusively use their clutch design. All engines would have to be free-air or fanned cooled because Brute had the first liquid-cooled engine and their gone. Long travel suspensions would be owned by Fast and use by anyone who will pay Karpik a fee. Oh yes, of course since Fast actually invented the ride forward design, any manufacture could buy that from him too.
So, since Fast made the first ride forward design (source

This is like Apple suing Microsoft over the GUI interface which Apple actually copied from Xerox. So Doo is suing Cat for a design they copied from Fast. This suit is going no where. Indy is right, Doo is jealous and sees Cat as a threat.
