Supreme Court Clears Patent Invalidity Suits

The Empiricist writes "The United States Supreme Court has cleared the way for entities to sue over the validity of a patent — even while paying user fees to the patent holder. The eight-to-one Medimmune v. Genetech decision, written by Justice Scalia, held that by paying royalties to a patent holder, one does not necessarily waive the right to challenge the validity of the patent."
