Don't cry for Google, but it lost another patent battle last week, involving the Motorola patents at the center of last year's $12.4 billion acquisition. In a case against Microsoft where Google sought $4 billion in royalties, U.S. District Judge James Robart instead set the amount at $1.8 million. Given that Google valued Motorola's patents at $5.5 billion when it closed the deal, this is hardly the kind of return on investment it thought it was getting on the once-great developer of mobile phones and related technology.
