Android may be under siege from Apple, Microsoft, Oracle, and other patent holders, but Google remains undeterred. It's doubling down, investing in patents through its acquisition of Motorola Mobility to arm its partners for a long war. The result may be that Android becomes more costly to handset makers and to Google. Even so, the company's mobile operating system appears to be destined to dominate.
It might have played out differently had Apple sought partners and allies rather than control, but that's not Apple's way. It might have played out differently had Microsoft not taken so long to move beyond the PC. But at the moment, the mobile race looks like it's Google's to win or lose.
