Toshiba Corp. said Tuesday it has filed a lawsuit in the Intellectual Property Court in Taiwan against Powerchip Technology Corp. and three other firms for infringing on the patent of its NAND flash memory, used in smartphones and tablet devices.
The company is demanding Powerchip, Powerflash Technology Corp., Zentel Electronics Corp. and C.T.C. Co. suspend the manufacture and sales of NAND flash memory products and pay ¥340 million in compensation, according to a Toshiba official.
Toshiba says the four companies have been using NAND flash memory without a license to use technologies covered by Toshiba’s Taiwan patents, and that it decided to take the legal action as Powerchip Technology has ignored its notices.
Toshiba also filed a damages suit against South Korean chipmaker SK Hynix Inc. in March as its predecessor allegedly obtained data on Toshiba’s NAND flash memory in an illegal manner.
