The drugstore chain has filed a lawsuit in Delaware against Theranos for violating some of the nondisclosure and confidentiality agreements the company agreed to when it partnered with Walgreens to provide lab testing services, reports TechCrunch. Walgreens formally severed its ties with Theranos earlier this year after a federal investigation into the company's blood testing technology. Walgreens has confirmed the lawsuit but won't comment further on it, while Theranos put out a statement saying:
"Over the years, Walgreens consistently failed to meet its commitments to Theranos. Through its mishandling of our partnership and now this lawsuit, Walgreens has caused Theranos and its investors significant harm. We will respond vigorously to Walgreens' unfounded allegations, and will seek to hold Walgreens responsible for the damage it has caused to Theranos and its investors."
