The business technology giant is asking for a total of $9.3 billion from Google relating to a lengthy legal battle over software copyrights, according to a report on Monday by IDG News Service.

Oracle claims that it should receive $475 million in damages in addition to $8.8 billion relating to “profits apportioned to infringed Java copyrights,” according to court documents cited in the report.

The two companies have long been at odds over whether Google improperly used so-called APIs (application programming interfaces) related to the Java programming language to create its Android operating system. Oracle (ORCL) claims that Google (GOOG) has not paid the company for its use of Java, which was developed by the tech company Sun Microsystems. Oracle acquired Sun Microsystems in 2010.

Although the two companies took the issue to court in 2012, a jury was unable to determine whether Google’s use of Java APIs were protected under fair use.
