Core Wireless Licensing, S.A.R.L. v. Apple, Inc., No. 17-2102 (Fed. Cir. 2018)Annotate this Case
Core sued Apple, alleging infringement of two patents concerning technology for wireless communications in a digital network. Claim 14 is directed to a mobile station, such as a mobile telephone, configured to synchronize to a base station using the same timing information for the uplink and downlink channels. Claim 19 is directed to a receiver, such as a mobile telephone, that can detect predetermined control messages where they are not otherwise expected. A jury found that Apple infringed both asserted claims and that neither was invalid. The court rejected Apple’s argument that the 151 patent was unenforceable due to implied waiver. The Federal Circuit affirmed in part. The jury’s finding of infringement of claim 14 was supported by substantial evidence. The issue of validity came down to a disagreement between the experts; the jury could reasonably credit the testimony of Core’s expert over that of Apple’s expert. The court remanded with respect to Apple’s implied waiver theory of unenforceability, based on actions taken by Nokia, the original assignee of one patent, during its participation with the standards-setting organization referenced in the patent. The district court did not make findings regarding whether either party inequitably benefited from Nokia’s failure to disclose, or whether Nokia’s conduct was sufficiently egregious to justify finding implied waiver without regard to any benefit resulting from that misconduct. The court reversed in part; Core’s theory of infringement is inadequate to support a judgment on claim 19.
