The jury in the California State Superior Court in San Jose, also found that Toshibas actions support an award of punitive damages, which are yet to be decided, Lexar said.
Evidence and argument will be presented to the jury on Thursday on the amount of punitive damages, it said in a statement.
A Toshiba spokesman in Tokyo said the company could not comment on the ruling as the jury is still continuing discussions on the case. The verdict holds Toshiba accountable for its conduct building Lexars trust to acquire our technology and then betraying that trust to partner with our competitor and compete against us, Eric Whitaker, Lexars general counsel, said in a statement.
Lexar said it expects the court to rule on its separate claim for unfair competition as well as on anticipated post-trial motions shortly after a hearing currently scheduled for April 13.
Based on the jurys verdict and findings, Lexar said it intends to ask the court for an injunction that bars the sale of Toshibas products in the United States, including Toshibas large and small block NAND flash memory chips, its CompactFlash, Secure Digital and xD Picture Card products.
