Prometheus Labs., Inc. v. Mayo Collaborative Servs., Case No. 2008-1403 (Fed. Cir. Sept. 16, 2009)
The United States Court of Appeals for the Federal Circuit (“Federal Circuit”) reversed the ruling of the United States District Court for the Southern District of California granting summary judgment of invalidity of U.S. Patents 6,355,623 (“the ’623 patent”) and 6,680,302 (“the ’302 patent”) under 35 U.S.C. § 101.
Circuit Judge Lourie delivered the opinion of the court, holding that patents claiming a method of treatment were drawn to patentable subject matter based on transformative administering and determining steps of the process. In so holding, the court noted that the “key issue for patentability” is “whether a claim is drawn to a fundamental principle or an application of a fundamental principle.” Prometheus Labs., Inc. v. Mayo Collaborative Servs., No. 2008-1403, slip op. at 8 (Fed. Cir. Sept. 16, 2009).
