Fresh From the Bench: Latest Federal Circuit Court Cases


Chemours Company FC, LLC v. Daikin Industries, Ltd., Appeal Nos. 2020-1289, -1290 (Fed. Cir. July 22, 2021)

In this week’s Case of the Week, the Federal Circuit reversed a PTAB decision in consolidated IPRs that two patents were unpatentable as obvious. The Court held that the Board erred in reaching its conclusions both in terms of what the prior art taught and in application of objective indicia of nonobviousness.

This consolidated appeal arises from two IPR decisions filed by Daikin with regard to Chemours’s ’431 patent and ’609 patent. The patents at issue “relate to a polymer with unique properties such that it can be ‎formed ‎at high extrusion speeds while still producing a high-‎quality coating on the communication ‎cables.”‎ The Board found all challenged claims of the ’431 and ’609 patents to be unpatentable as obvious in light of the Kaulbach patent.
