Sure, Motorola had $3 billion of cash on its balance sheet when it was acquired and Google later sold a set-top box division for $2.4 billion. But that still leaves Google CEO Larry Page left to explain why he’s only getting $3 billion for the remaining net investment of $7 billion. "Patents," he'd likely reply.
Analysts speculated all along that Google made the hasty deal only to get control of Motorola’s vast trove of about 17,000 patents. At the time, Apple (AAPL) and Microsoft (MSFT) appeared to be waging an intellectual property war to beat back the Android challenge. Many of those battles continue and intellectual property attorneys are split over whether the Motorola patents have helped Google much, if at all.
Still, Google said it would retain "the vast majority" of patents from Motorola in the sale to Lenovo.
That would leave the company with a still significant patent stash and a net outlay, after all the wheeling and dealing, of about $4 billion. Of course, Google also reported operating losses for Motorola as its owner, including $645 million in the first nine months of 2013 and $1.1 billion in 2012. A portion of the losses consisted of non-cash charges for stock-based compensation and other items.
