February 2, 2015 – United States District Court Judge Nathaniel M. Gorton issued a decision on January 30, granting in part and denying in part a motion by ZOLL Medical Corp. for summary judgment of non-infringement and limitation of damages in ZOLL Medical’s litigation against Koninklijke Philips, N.V. The patents at issue are U.S. Patent No. 7,463,922, entitled “Circuit and Method for Analyzing a Patient’s Heart Function Using Overlapping Analysis Windows,” and U.S. Patent No. 5,441,520, entitled “Defibrillator Patient Connection System With Automatic Identification.” The technology at issue relates to ZOLL Medical’s external cardiac defibrillators, which are medical devices that can deliver an electrical shock through electrodes placed on a patient who is experiencing a rapid, erratic heartbeat (“ventricular fibrillation”). Judge Gorton denied ZOLL Medical’s summary judgment motion with respect to non-infringement, finding that Philips raised a genuine issue of material fact regarding infringement of the patents-in-suit. However, Judge Gorton allowed summary judgment regarding limiting Philips’ damages claim for the ’922 patent. The case is captioned: Koninklijke Philips, N.V. et al. v. ZOLL Medical Corp., 12-cv-12255 (D. Mass.).
