Mitsubishi Plastics Seeks Inter Partes Review of Lithium Battery Separator Patent, Among the Requests Week of March 17, 2014

Scott Daniels and Cindy Chen | March 24, 2014

In January Celgard – a subsidiary of Polypore International – sued LG for infringement of U.S. Patent No. 6,432,586. The ‘586 patent broadly claims a separator for lithium batteries, that includes “a ceramic layer is adapted … to block dendrite growth and to prevent electronic shorting … .”  This case follows earlier infringement actions against Sumitomo and SKMitsubishi Plastics has now filed for inter partes review of Celgard’s ‘586 patent (see inter partes review Request No. (5)). 

Ericsson requested review of an Intellectual Ventures wireless patent, U.S. Patent No. 7,496,674, that IV has asserted against four telephone companies (see inter partes review Request No. (8)). The ‘674 patent has an unusually long and complex assignment history at the Patent Office. 

ZTE asserted a novel legal theory against a wireless device patent owned by InterDigital: the challenged claims are invalid, in part, because the claims of a related patent were found by the U.S. ITC to be invalid over similar art, see In the Matter of Certain Wireless Devices with 3GCapability and Components Thereof, USITC Inv. No. 337-TA-800, Comm’n Op. (Dec. 20, 2013) (see inter partes review Request No. (6)).
