Apple can build a GPU without infringing ImgTec patents, through a patent agreement with another GPU maker(including ARM, so they're pretty much covered).
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.
