Following Kappos v. Hyatt, Supreme Court Denies Certiorari in Streck v. R&D Systems

The Supreme Court on Monday denied Research & Diagnostics Systems Inc.’s petition for a writ of certiorari to consider the degree of deference that should be afforded administrative decisions of the PTO on appeal to Federal District Court when new evidence is presented. Streck Inc. sued R&D Systems, a blood test technology company, for patent infringement in Federal District Court. A Nebraska jury held R&D Systems liable for infringement following a finding that it had failed to establish a claim of priority over the disputed patents. In a parallel interference proceeding, the PTO awarded priority to R&D Systems. Streck appealed the PTO ruling in District Court under 35 U.S.C. § 146, where a patent holder may appeal a PTO determination concerning priority made pursuant to an interference proceeding.
