The New Zealand Herald is reporting that Google senior vice president and chief legal officer David Drummond is accusing Microsoft, Apple and Oracle of using patents in an attempt to kill the innovative and popular Android phone operating system. Android is an open source phone operating system based on Linux. It has taken the market by storm, and is now the most popular operating system for smartphones in the world. Ironically Oracle has made use of Linux in it's "unbreakable Linux" campaign. Apple also used a open source kernel for it's OSX operating system. However, now that a open source system is giving them real competition we have seen a significant turn around in support for open source, and a direct attack on open source systems using the law rather than technical innovation.
