Microsoft announced two new Android patent deals on Thursday.

The software giant has managed to secure deals with Acer and ViewSonic. The first deal will see Acer ink a patent license agreement that includes coverage under Microsoft’s patent portfolio for Acer’s tablets and smartphones running the Android platform. “We are pleased that Acer is taking advantage of our industrywide licensing program established to help companies address Android’s IP issues,” said Horacio Gutierrez, corporate vice president and deputy general counsel of Intellectual Property and Licensing at Microsoft. “This agreement is an example of how industry leaders can reach commercially reasonable arrangements that address intellectual property.” Microsoft did not disclose the full details of the Acer deal and whether the company will recieve royalties from Acer as a result.

Microsoft’s second deal sees ViewSonic’s tablets and mobile phones running the Android or Chrome Platform protected under a new agreement. Microsoft will receive royalties from ViewSonic under the agreement. “We are pleased that ViewSonic is taking advantage of our industrywide licensing program established to help companies address Android’s IP issues,” said Horacio Gutierrez, corporate vice president and deputy general counsel of Intellectual Property and Licensing at Microsoft. “This agreement is an example of how industry leaders can reach commercially reasonable arrangements that address intellectual property.”

Microsoft has previously inked patent protection deals with Wistron, General Dynamics Itronix,Velocity Micro and Onkyo. The agreements all appear to be identical to each other and provide cash royalties to Microsoft. The deals follow a  HTC and Microsoft patent agreement signed last year relating to HTC’s mobile phones running Android. Although the terms of the deal were undisclosed, it was recently reported that Microsoft receives $5 for every HTC device sold. Microsoft is widely believed to generate more revenue from Android patents than its own Windows Phone licences. Microsoft CEO Steve Ballmer has previously said that Android is not free. “Android has a patent fee. It’s not like Android’s free,” he said in October last year. Microsoft is also alleged to be in talks with Samsung over an Android patent deal.

Microsoft’s fresh Android patent agreements come just weeks after Google accused the company of “getting into bed” with Apple to attack Android. “Microsoft and Apple have always been at each other’s throats,” said Google’s chief legal officer, David Drummond. “So when they get into bed together you have to start wondering what’s going on.” Google believes that Android’s success has created an organised campaign against Android by Microsoft, Oracle, Apple and others through patents. “This anti-competitive strategy is also escalating the cost of patents way beyond what they’re really worth,” claims Drummond.
