Golden Gate University Law Review


Currently, a method of diagnosing a disease can be broadly claimed in a patent. The United States Supreme Court initially granted certiorari in Metabolite Labs to decide whether the method-of-diagnosis claim was patentable. Later, the Court dismissed certiorari as improvidently granted. This Note asserts that the Court should have adjudicated the case because there is a great need to clarify what is patentable subject matter for method claims that do not entail a physical transformation of matter, particularly in view of the seeming inconsistency between Diamond v. Diehr and State Street Bank & Trust Co. v. Signature Financial Group.
