Google's most recent filing to the SEC has revealed how the company came to that $12.4 billion valuation of Motorola. Unsurprisingly, its intellectual property portfolio comprised the bulk of the price -- with Mountain View stumping up $5.5 billion for the "patents and developed technology" owned therein. Larry Page claimed that the deal would "supercharge" the Android ecosystem, which led to the company paying $2.6 billion for goodwill -- which was only expected to arise once the buyout was completed. The company spent $630 million on "net assets," $2.9 billion to buy the phone maker's cash reserves and $730 million on customer relationships. During its most recent earnings call, Google said it had nothing to announce regarding the newest member of the family -- but perhaps we can look forward to some more exciting hardware... pretty please?
