Celgard Successfully Sues Targray on Infringement of Celgard's Ceramic Coated Battery Separator Patent
In the case, Targray did not contest the infringement, validity or enforceability of Celgard's patents. Targray also agreed to not challenge the validity of Celgard's '586 (now '520) and '867 Patents.
The successful outcome of the Targray case further solidifies the integrity of Celgard's intellectual property (IP) regarding coated and uncoated separators for lithium-ion batteries.
Earlier, Celgard successfully settled two suits against MTI Corporation of California (MTI). The first was a patent suit in California under the same '586 Patent seeking relief from MTI for selling infringing ceramic coated battery separators manufactured by Foshan Jinhui Hi-Tech Optoelectronic Material Co., Ltd. in China . The second was a trademark suit in North Carolina seeking relief from MTI for selling unauthorized and counterfeit battery separators. MTI and several related MTI companies agreed to stop selling all coated and uncoated battery separators.
Celgard will continue to take appropriate steps to prevent the unfair exploitation of its technology and IP to safeguard its assets and customers.
