The patent war is heating up. After being foiled by Apple, Microsoft and RIM to acquire Nortel Networks’ patent portfolio, Google is now acquiring Motorola Mobility primarily for its patent portfolio. The thing is, Motorola builds it’s own Android mobile phones and tablets. Back when Nokia was still exploring Android, it asked for preferential treatment, which Google rightly denied. One of the reasons that led Nokia to instead go to the Microsoft and the Windows Phone platform. Now that Google will own Motorola, will it be giving preferential treatment? Will it be able to avoid doing that? This is probably something all of Google’s Android partners are thinking even as they heap praise on Google for this latest move.
