Google executives took a deep breath before the recent holiday weekend following the news that the search giant could owe Oracle (News - Alert) as much as $2.6 billion for allegedly violating Java patent violations, several media outlets reported.

A court filing was made Tuesday in U.S. District Court for the Northern District of California, according to PC World.

“The final amount could falls between the “breathtaking” $1.4 billion and $6.1 billion range Google (News - Alert) previously cited based on its own interpretation of Oracle expert Iain Cockburn’s damages report,” the June 28 report said.

The Redwood Shores, Calif.-based tech company alleges that “Google infringed Oracle patents on the Java programming language and its use in the Android (News - Alert) operating system,” the LA Times reported. Oracle is also seeking 15 percent of the revenue Google receives from advertising on its mobile operating system, the report said.

But in a letter filed earlier this month, Google attorney Scott Weingaertner said, “Even the low end of Cockburn’s range is over 10 times the amount that Sun Microsystems (News - Alert), Inc. made each year for the entirety of its Java licensing program and 20 times what Sun made for Java-based mobile licensing,” according to PC World’s June 30 report.

In a June 6 letter to U.S. District Judge William Alsup, Google attorneys called the multi-billion dollar number, “A breathtaking figure that is out of proportion to any meaningful measure of the intellectual property at issue.”

Last year, Oracle sued Google claiming that its Android mobile operating system was in violation of several patents for Java, which Oracle acquired through the purchase of Sun Microsystems in January 2010.

It has been speculated that despite Google’s motion for filing the case under seal, shareholder confidence may already have been shaken as a result of the case in general, TMCnet recently reported. Google shares hit a nine-month low in June, sliding below $490.
