CAFC Affirms Samsung’s IPR Win

Written May 28, 2019

The United States Court of Appeals for the Federal Circuit on May 23, 2019, found Papst Licensing GMBH & Co.'s software patent, which is related to a software interface device with high data transfer rates, invalid because it was covered by other patented technology and published research.

Affirming the PTAB, the Federal Circuit said that Papst was precluded from challenging the PTAB decision because it had previously lost two IPR challenges for two related patents based on the same prior invention.
