Oracle, the company who acquired Sun Microsystems, the Java programming language and related technology in a nice package deal, accused Google of patent and copyright infringement in relation to those technologies. Based on its response, Google isn't happy:
We are disappointed Oracle has chosen to attack both Google and the open-source Java community with this baseless lawsuit. The open-source Java community goes beyond any one corporation and works every day to make the web a better place. We will strongly defend open-source standards and will continue to work with the industry to develop the Android platform.
Sounds like Google is ready to fight. [TechCrunch]
