Smith & Nephew, Inc. v. Rea

by
Synthes owns a patent, issued in 2006, directed to a system for repairing fractures in long bones, such as the femur, using a bone plate along the outside of the fractured bone, attached by anchors inserted through predrilled holes in the plate and then into the bone. The Patent and Trademark Office granted Smith & Nephew’s 2009 reexamination request and rejected all 55 claims of the patent as obvious based on prior art. The Board of Patent Appeals upheld the rejections of 31 of the claims, but reversed the rejections of 24. The Federal Circuit reversed, holding that Smith & Nephew met its burden of showing that the claims at issue would have been obvious. The patentability of the invention turns on the structure of the holes, not the special nature of the non-locking screws. The conical, partially threaded holes were well known in the art, as was the advantage of adding more of them to the head of a bone plate in place of unthreaded holes. The screws and the holes perform a conventional, expected function in securing the plate. View "Smith & Nephew, Inc. v. Rea" on Justia Law
