Toshiba is seeking $1.1 billion in damages in a lawsuit filed earlier this year alleging that rival SK Hynix illegally acquired flash-memory technology, the latter disclosed Monday in a regulatory filing.
The amount of damages sought was not previously known, according to Reuters.
Both Toshiba and SanDisk filed suit against South Korea-based SK Hynix in March, saying the company profited from the theft of information about flash-memory technology. According to, the alleged data leak resulted in the losses of more than $980 million for Toshiba. In March, Tokyo police arrested a former SanDisk engineer under suspicion of providing flash memory information to SK Hynix in 2008.
In 2004, Toshiba sued SK Hynix for alleged infringement of memory patents. They settled the dispute three years later.
Representatives for Toshiba and SK Hynix weren't immediately available for comment.
