Japanese firm Asahi Kasei has won a two-year lithium-ion separator patent infringement case against firms Shenzhen Xu Ran (旭冉) Electronic and Shenzhen Xu Ran (旭然) Electronic.
Asahi filed a patent infringement lawsuit based on the Chinese patent of separator for lithium-ion secondary battery (Patent No.: ZL200680046997. 8) with the Shenzhen Intermediate People’s Court in August, 2018.
Shenzhen Xu Ran (旭冉) Electronic and Shenzhen Xu Ran (旭然) Electronic— both sellers of separator film for lithium-ion secondary battery in Shenzhen, China— were joint defendants.
Both firms have been ordered to stop selling their “single-layer W-scope” battery separators in China and compensate Asahi for damages.
A statement from Ashai read: “It is hereby notified that, the claims of Asahi Kasei for patent infringement were supported by the court with judgment of April 2020 and Xu Ran Electronic was ordered to stop the sale of the infringing products indicated above and make compensation for the related damages.”
The judgment of the court is not final and can be appealed by Xu Ran Electronic.
