Two Silicon Valley heavyweights are about to reenact the Java wars: this time, in a court room.

Oracle issued a press release late Thursday saying it has filed suit against Google for infringing on copyrights and patents related to Java, which Oracle acquired along with Sun Microsystems earlier this year. The terse release claimed Google “knowingly, directly and repeatedly infringed Oracle’s Java-related intellectual property.”

A copy of the complaint (.PDF), which was filed in the U.S. District Court for the Northern District of California, says that “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.”

A Google representative said the company had not yet been served with the lawsuit, and therefore couldn’t comment until it had a chance to review it. An Oracle representative declined to comment beyond the complaint.
