Chemours Co. FC, LLC v. Daikin Industries, Ltd., et
al., Nos. 2020-1289, -1290 (Fed. Cir. (PTAB) July 22,
2021). Opinion by Reyna, joined by Newman. Opinion concurring in
part and dissenting in part by Dyk.
Daikin petitioned for IPR of two patents owned by Chemours
directed to a unique polymer for insulating communication cables
formed by extrusion. The claimed polymer can be formed at high
extrusion speeds via a "high melt flow rate." Daikin
asserted that the claims were obvious over a patent issued to
Kaulbach.
