The DOJ joined the lawsuit in 2010 and alleged that U.S. agencies paid "far more" than they should have for Oracle products, the DOJ said in a press release.

"Companies that engage in unlawful or fraudulent practices to secure government business undermine the integrity of the procurement process and create an unfair advantage against the majority of companies that are playing by the rules," Tony West, assistant attorney general for the DOJ's Civil Division, said in a statement. "Resolutions like this one ... demonstrate our commitment to ensure taxpayers are not overpaying for the products and services they receive."

The DOJ's recoveries in False Claims Act cases since January 2009 exceed $7.8 billion.
