Microsoft’s lawsuit against Samsung was unsealed on Friday, revealing that the software maker believes it is owed $6.9 million in unpaid interest from last year.
Microsoft sued in August, asking a federal court to rule that its Nokia purchase didn’t breach the company’s contract with Samsung. That contract calls for the Korean electronics giant to pay Redmond a royalty for each Android phone and tablet it makes.
A lot is at stake in the case, as is made clear by the details unsealed Friday. Microsoft notes in the suit that Samsung paid it $1 billion last year under the patent agreement.
“We are confident that our case is strong and that we will be successful,” Deputy General Counsel David Howard said in a statement on Friday. “At the same time, Microsoft values and respects our long partnership with Samsung, is committed to it, and expects it to continue.”
Here’s the unredacted suit:
