Kenyon won four summary judgment motions on behalf of Delphi Automotive Systems, LLC in a declaratory judgment action filed by the company in the Eastern District of Michigan. After certain of its customers had been sued in Texas, Delphi filed this action against Automotive Technologies International, Inc. ("ATI"), seeking a declaratory judgment of the invalidity of certain ATI patents relating generally to occupant sensors for airbag control in automobiles. The infringement counterclaims filed by ATI centered around Delphi's Passive Occupant Detection System ("PODS") products.
During the course of the litigation, ATI dropped allegations of infringement with respect to certain of its patents, and the case proceeded with respect to representative claims of four remaining patents. The court construed the claims of these patents in September 2009, and Delphi filed summary judgment motions of patent invalidity in July 2010. After hearing oral arguments on January 6, 2011, the Honorable Robert H. Cleland ruled in favor of Delphi, finding all four of the patents-in-suit invalid as either anticipated by or obvious over the prior art. Case number 08-11048 (2011).
