Supreme Court of United States.
Justice SOTOMAYOR delivered the opinion of the Court.
Under § 282 of the Patent Act of 1952, "[a] patent shall be presumed valid" and "[t]he burden of establishing in-validity of a patent or any claim thereof shall rest on the party asserting such invalidity." 35 U.S.C. § 282. We consider whether § 282 requires an invalidity defense to be proved by clear and convincing evidence. We hold that it does.
