It is reported that Apple has been filing numerous lawsuits against companies that use the Google-created, open operating system Android over recent months. Apparently, Apple and Microsoft have no reason to want Android to be successful; thus patent challenges have been brought against companies like Samsung and HTC who use Android. This is one of the reasons that Google is reported to have spent $40/share or $12.5 billion to purchase Motorola Mobile Holdings. MMH itself is not a particularly strong player in the current mobile phone market, in fact, it has been pretty much a bench-warmer as of late, but it possesses a trove of ~25,000 patents. It is suggested that acquiring these patents as defensive tools to use in patent challenge litigation was the animating principle beyond Google’s acquisition. Although some analysts doubt whether Google will expand into actually manufacturing mobile phones, a resurgent Motorola backed by Google’s warchest is now a possibility. However, the immediate goal seems to be protecting Android, not reviving Motorola.
