In re: NuVasive, Inc..

by
NuVasive’s patent describes and claims implants for spinal fusion surgery. On inter partes review, the Patent Trial and Appeal Board cancelled all but one challenged claim under 35 U.S.C. 103, finding in one prior-art reference (Michelson), a spinal fusion implant that meets two of the claim requirements of the NuVasive patent—having a length both greater than 40 mm and at least 2.5 times its width. NuVasive argued that it did not receive adequate notice of or opportunity to address that reading of Michelson and its consequences for the overall obviousness analysis. The Federal Circuit vacated in part and remanded Medtronic’s petition put NuVasive on notice that Medtronic was relying on particular portions of Michelson to teach the NuVasive patent’s claimed long-and-narrow implants. Medtronic’s petition did not, however, notify NuVasive of the assertions about the pertinent portions of Michelson that later became critical; the Board’s ultimate reliance on that material, together with its refusal to allow NuVasive to respond fully once that material was called out, violated NuVasive’s rights under the Administrative Procedure Act.
