Federal Circuit Affirms PTAB Invalidation of Claims Federal Circuit Previously Upheld as Valid

Previously, the ITC instituted an investigation of Instradentdental implants based on a complaint filed by Nobel alleging violations of 19 U.S.C. § 1337 by reason of importation of an implant product infringing the ’977 patent and another patent. The ITC’s Administrative Law Judge issued an Initial Determination finding claims 1–5 and 19 anticipated by the ABT catalog but the ITC later issued a Commission Opinion finding that Instradent failed to show by clear and convincing evidence, the standard applied by the ITC, that the ABT catalog is prior art under § 102(b). A Federal Circuit panel affirmed the ITC’s decision without opinion. Subsequently, Instradent petitioned for IPR of claims 1–7, 9, and 13–20 of the ’977 patent, and Nobel filed a statutory disclaimer of claims 9 and 13–18.
