Oracle filed a complaint against Google for patent and copyright infringement Thursday evening related to the development of the Android mobile operating system. Oracle spokesperson Karen Tillman in a press release posted by Mark

etWatch explained that the lawsuit's complaint is that Android infringes upon Oracle's Java-related intellectual property.

The integrated business software and hardware systems company filed this complaint with the US District Court for the Northern District of California, which was quoted by CNET: "Android (including without limitation the Dalvik VM and the Android software development kit) and devices that operate Android infringe one or more claims of each of United States Patents Nos. 6,125,447; 6,192,476; 5,966,702; 7,426,720; RE38,104; 6,910,205; and 6,061,520." The complaint calls for a jury trial.

Google attracted attention when they began Android development in 2007, a software system that uses Java-derived tech, Oracle argues, without a proper license. Android competes against Java, which is implemented on other mobile phones. Developed by Sun Microsystems, Java was acknowledged in the documentation as one of the most significant technologies that Oracle acquired from Sun when the latter was acquired by Oracle.

Apparently the suit will not be a surprise to Google. James Gosling, an author of Java, mentioned in his blog Nighthacks that during the Oracle-Sun integration meetings, Oracle lawyers were asking questions about the patent situation between Sun and Google.

Google's response via TechCrunch has labelled the suit contrary to the open source spirit of Java. “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.”
