TOKYO (Reuters) - Toshiba Corp, a top maker of flash memory chips used in smartphones, said on Tuesday it has filed suit in a Taiwan court against Taiwan's Powerchip Technology Corp and three other firms charging infringement of its flash memory patents.
A Toshiba spokesman said the company was seeking T$100 million ($3.3 million) in compensation in the case. The company is also seeking a halt of the sale and manufacture of products that it says infringe its patents.
In March, Toshiba also filed suit against South Korea's SK Hynix Inc seeking damages in a case over suspected theft of data related to its flash memory chip technology. ($1 = 29.9855 Taiwan New Dollars)
