Court Denied In Part and Granted in Part Plaintiff’s Motion to Strike Contentions and Grants Defendant’s Motion to Amend its Invalidity Contentions

November 15, 2017 – On November 13, 2017, the court granted Plaintiff Karl Storz Endoscopy-America’s motion to strike portions of Defendants Stryker Communications, Inc.’s and Stryker Corporation’s supplemental invalidity contentions for asserting nearly 500 prior art references as well as for insufficient disclosure of unpatentability contentions. However, the court denied Plaintiff’s motion to strike the portions of Defendant’s supplemental invalidity contentions pertaining to its Section 112 defenses because they were sufficiently disclosed. The court granted Defendant’s motion to amend its invalidity contentions because Plaintiff had delayed in pursuing its motion to strike.

The patents at issue are United States Patent Nos. 8,069,420 entitled “System for Controlling the Communication of Medical Imaging Data,” 7,471,310 entitled “Intelligent Camera Head,” 7,821,530 entitled “Intelligent Camera Head,” and 7,844,657 entitled “System for Controlling Medical Devices.” The case is captioned Karl Storz Endoscopy-America, Inc. v. Stryker Corporation et al., 3-14-cv-00876, and is pending in the Northern District of California.
