Walgreens has filed a breach of contract lawsuit against Theranos, the embattled blood-testing startup.

The lawsuit was filed Tuesday in Delaware’s district court. Details on Walgreen’s complaint weren’t immediately available because the suit was sealed by the court.

The Wall Street Journal is reporting that Walgreens is looking for $140 million in damages, claiming that Theranos misled Walgreens about how far along its blood-testing technology was when the original partnership was inked.

Walgreens, once Theranos’ biggest partner, terminated its relationship with the company in June. It had operated Theranos Wellness Centers, where people could go have their blood tested in the company’s stores.
