samsung-vs-microsoft-700x325On Friday, Microsoft’s lawsuit against Samsung was unsealed, revealing that the software maker believes it is owed $6.9 million in unpaid interest from last year.

The software giant 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.

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.
