Clients Johnson & Johnson

Jones Day successfully represented 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 on all four patents. On appeal, the Federal Circuit affirmed the district court judgment without opinion in an order pursuant to Federal Circuit Rule 36.
