Perhaps not. Existing GPU makers protect themselves through cross-licensing their patents: you can use mine if I can use yours.

However, it sounds like ImgTec is considering going full-on troll, so they won't need access to the other patents any more and can just sit under their bridge extorting tolls.

Patent trolls are non-practicing entities. Imagination Technologies is hardly a non-practicing entity.

Sure, today. But they're "concentrating on the licensing business".
