Clients Johnson & Johnson

Jones Day represents Johnson & Johnson subsidiaries DePuy Orthopaedics, Inc.; DePuy Synthes Sales, Inc.; and DePuy Synthes Products, Inc. in their defense against claims of patent infringement brought by MedIdea, L.L.C. relating to the sale of their flagship posterior stabilized knee replacement product, Attune®. MedIdea accused DePuy's Attune® product of infringing four patents directed to a multi-cam posterior stabilized knee prosthesis. Following the court's claim construction order, MedIdea stipulated to non-infringement on three of the four patents-in-suit, but maintained its assertion as to the fourth patent. Jones Day requested an expedited summary judgment procedure and, following full briefing, the district court granted summary judgment of non-infringement as to MedIdea's final patent and entered judgment in DePuy's favor.
