New Suit Targets C.R. Bard

| Printer friendly version

C.R. Bard, Inc., and Bard Peripheral Vascular, Inc., are the latest targets of a series of lawsuits brought by LifeScreen Sciences LLC.  LifeScreen filed a patent infringement lawsuit in the District of Delaware on January 30 accusing C.R. Bard and Bard Peripheral of patent infringement.  LifeScreen Sciences and LifePort Sciences have recently filed patent infringement suits against Cook, Inc., Cordis Corporation, Medtronic Corp., W.L. Gore & Associates Inc. and Endologix, Inc.

LifeScreen’s latest lawsuit alleges that C.R. Bard’s Meridian vena cava filter infringes several patents, including U.S. Patent No. 6,468,290, entitled “Two-Planar Vena Cava Filter With Self-Centering Capabilities,” which issued in 2002.  The patent relates to a two-plane filter with filter wires with extensions that are applied against the wall of a vein and compel the filter “to adopt a position with its axis generally coincident with the axis of the vein…”   The ‘290 patent was originally assigned to SciMed Life Systems, Inc.

LifeScreen’s other lawsuits have targeted similar technologies.  For example, on January 23, 2013, LifeScreen filed lawsuits in Delaware and Texas alleging infringement of U.S. Patent No. 6,214,025, entitled “Self-Centering, Self-Expanding and Retrievable Vena Cava Filter,” a patent originally assigned to Boston Scientific.
