Being accused of copying only happens on copyright issues. To my
knowledge it APIs and instruction sets are commonly regarded
non-copyrightable (otherwise clones and emulators would have a hard
time - e.g. Microsoft can't do anything against WINE).
The way ARM would get at you would be by patents. In a patent suit it
doesn't matter if you invented something all on your own without knowing
of the patent or existing technology. If you infringe their patents
they can always sue you (and probably win).
