Reliance on the Same Prior Art Dooms Medtronic's Attempt to Correct its Previously Rejected IPR Petition
In IPR proceeding involving Medtronic, Inc. v. NuVasive. Inc., the petitioner, Medtronic, file a petition seeking review of U.S. Patent No. 8,361,156 relating to a spinal implant and methods of spinal fusion using the implant. The petition was Medtronic's third IPR petition challenging the validity of claims in the '156 patent. One of the two earlier petitions was granted while the other was denied. According to Medtronic, the instant petition "remedies the deficiencies of the [earlier denied] petition, and also adds new arguments and evidence as to the length disclosure of [prior art publication to Frey]."
In its preliminary response, the patent owner argued that the petition "is essentially a duplicate of its previously denied petition." As summarized below, the Board agreed with the patent owner and denied Medtronic's third challenge to the validity of claims of the '156 patent based on "the same or substantially the same prior art or arguments" presented in the earlier, denied petition.
