Last week, in Ancora Technologies v HTC America, the Federal Circuit reversed a lower court’s invalidity ruling under 35 USC §101 by concluding that Ancora’s claimed subject matter was concrete—not abstract—because it assigned specific functions to specific parts of a computer to improve computer security… This case is yet another in a string of post-Alice cases suggesting that patents should be drafted with an emphasis on the technical problem and technical solution delivered by the claims.

The United States Court of Appeals for the Federal Circuit recently issued a ruling on discussing the equitable doctrine of implied waiver; a decision that will be particularly important for those participating in the standard setting process and engaging with standard setting organizations, or SSOs as they are sometimes called. According to the Federal Circuit, failure to disclose patents and applications relevant to a standard may render a patent unenforceable based on an implied waiver.  See Core Wireless Licensing S.A.R.L. v. Apple Inc., No. 17-2102, 2018 (Fed Cir. Aug. 16, 2018) (Before Reyna, Bryson, and Hughes, Circuit Judges) (Opinion for the court, Bryson, Circuit Judge).

The Federal Circuit, however, found the district court’s enforceability finding to be unsupported by evidence. The rejection of Nokia’s proposal did not obviate Nokia’s requirement to disclose inventions that might be essential to the standard. Dr. Walker’s uncontroverted testimony explained that patent applications are to be disclosed at the time proposals are presented. “[A]n ETSI member’s duty to disclose a patent application on particular technology attaches at the time of the proposal and is not contingent on ETSI ultimately deciding to include that technology in an ETSI standard,” Bryson explained. Notwithstanding, the Federal Circuit elected to vacate this ruling rather than electing to reverse the district court because the existence of an implied waiver is an equitable defense.

Core Wireless sued Apple for infringing its patent directed to a cellular network system including a mobile station providing for improved transmission of data packets. The jury found that Apple did not infringe Core Wireless’ patent. At issue on appeal is whether the district court misapplied the magistrate judge’s pretrial claim construction and whether the claim construction adopted by the district court when ruling on Core Wireless’ JMOL was erroneous… Ultimately, the Court concluded that the district court correctly denied Core Wireless’s motion for judgment as a matter of law and properly upheld the jury’s verdict of noninfringement.
