Stormwave0 writes "A Microsoft appeal against a decision for AT&T and their speech recognition patent has reached the Supreme Court. AT&T has argued that they did not license software using the patent for sales overseas. Microsoft, in the original case, argued "that it wasn't really liable for infringing on AT&T's licensing rights because it only supplied the golden disk to the replicator one time, and that disk did not really contain software in a usable form anyway." With that argument rejected, the case has moved in an unexpected direction. The court is now debating whether or not software is actually patentable."
