Microsoft is chasing down Huawei in search of a patent licensing agreement, The Guardian reported on Tuesday. “Yes, Microsoft has come to us,” Huawei Devices chief marketing officer Victor Xu told The Guardian. “We always respect the intellectual property of companies. But we have 65,000 patents worldwide too. We have enough to protect our interests. We are a very important stakeholder in Android.” Xu also said that “negotiations are in progress” with Microsoft, which takes home an estimated $444 million annually from Android royalties. Microsoft has a cross-licensing agreement with Samsung and has similar deals with HTC, ViewSonic and other Android device vendors. It is expected that Microsoft may soon hunt down Amazon for an agreement related to its new Android-powered Kindle Fire tablet, too.
