microsoftlogo1-1024x680Windows Phone may be floundering, but Android’s success has been a fiscal boon to Microsoft. The company made $1 billion last year from a patent licensing deal that it struck with Samsung over certain features in Android that allegedly infringe the Redmond-based company’s intellectual property, according to court filings revealed today.

The filings, which were first spotted by Re/code, are a part of the lawsuit Microsoft launched in August, alleging that Samsung was attempting to back out of its patent licensing deal because of Microsoft’s acquisition of Nokia. At the time the lawsuit was launched, the documents were kept under seal, though Microsoft provided a copy of the complaint with some of the fiscal information redacted.

Microsoft alleges that Samsung owes it $6.9 million in back interest, and wants the court to declare that the contract between the two parties will stand, even after Microsoft purchased Nokia.

In a blog post this afternoon, Microsoft deputy general counsel David Howard gave the company’s position.

Microsoft and Samsung agreed on the terms of a patent license agreement and a separate business collaboration agreement, the latter of which is unique to our relationship with Samsung and, as explained in paragraph 35 of the complaint, was aimed at promoting the development and sale of Windows smartphones and tablets by Samsung. Samsung has suggested that Microsoft has breached the business collaboration agreement. We disagree, and that’s why we asked the court to rule that Microsoft is not in breach. Second, Microsoft has asked for $6.9 million in damages due to unpaid interest from last year.

The full complaint is embedded below.
