Analysts do the math: #Google will pay $510,204.08 for each of #Motorola 's patents

Rajeev Chand, managing director and head of research at Rutberg & Co., said patents are the principal driver. He points out that Google can mitigate or eliminate the patent risk for Android, which could free up as much as $8 per device in royalties. Other drivers for the deal include development in new markets, specifically mobile payments, and developing a vertically integrated solution to more effectively compete with Apple, Chand wrote.
