One of Theranos Inc.’s biggest financial backers has sued the embattled startup and its founder for allegedly lying to attract its nearly $100 million investment, the Wall Street Journal reported today. Partner Fund Management LP, a San Francisco-based hedge fund, filed the suit in Delaware Court of Chancery Monday afternoon, a letter to the hedge-fund’s investors says. “Through a series of lies, material misstatements, and omissions, the defendants engaged in securities fraud and other violations by fraudulently inducing PFM to invest and maintain its investment in the company,” says the letter. The letter says that Theranos, its founder Elizabeth Holmes and a former executive deceived the hedge fund by claiming it had developed “proprietary technologies that worked,” and was close to getting regulatory approvals.
