We have a responsibility to our employees, customers, partners and shareholders to safeguard our intellectual property, Microsofts corporate vice president and deputy general counsel for litigation David Howard told Bloomberg. Motorola is infringing on our patents and we are confident that the ITC will rule in our favor. 

Google recently announced its intentions to purchase Motorola Mobility for $12.5 billion in an effort to bolster its patent portfolio and help its Android partners fight in lawsuits against Apple and Microsoft. 

A Motorola Mobility spokeswoman told Bloomberg that the company is vigorously defending & against Microsofts patent attack business strategy, and that the company has also brought legal actions of our own in the U.S. and in Europe to address Microsofts large scale of infringement of Motorola Mobilitys patents.
