Nerval's Lobster writes "Even before the Google acquisition, Motorola Mobility was engaged in a major legal battle with Microsoft, insisting that the latter needed to pay around $4 billion per year if it wanted to keep using Motorola's patents related to the H.264 video and 802.11 WiFi standards. (The patents in question affected the Xbox and other major Microsoft products.) Had that lawsuit succeeded as Motorola Mobility originally intended, it would have made Google a boatload of cash—but on April 25, a federal judge in Seattle ruled that Microsoft's royalty payments should total around $1.8 million per year. 'Based on Motorola's original demand of more than $4 billion per year from Microsoft,' patent expert Florian Mueller wrote in an April 26 posting on his FOSS Patents blog, 'it would have taken only about three years' worth of royalties for Microsoft to pay the $12.5 billion purchase price Google paid (in fact, way overpaid) for Motorola Mobility.' This latest courtroom defeat also throws into question the true worth of Motorola Mobility's patents. After all, if the best Google can earn from those patents is a few pennies-per-unit from its rivals' products, that may undermine the whole idea of paying $12.5 billion primarily for Motorola Mobility's intellectual-property portfolio.
