After a six-hour session, executives from Google and Oracle were unable to settle an ongoing copyright lawsuit between the two companies, according to new court documents.

Google CEO Sundar Pichai and Oracle CEO Safra Catz, along with other executives from both companies, met on Friday to try to settle the suit, which Oracle filed in 2012.

Last month, Google said that its damages expert strongly disagreed that it should owe Oracle upward of $8 billion for using certain parts of Oracle's software in its smartphone operating system, Android.

Because an agreement couldn't be made, the next phase of the case will head to court in May, where a jury will decide if Google had the right to use certain parts of Oracle's programming language, Java, free or if it owes Oracle damages.

This is the second time the two companies tried and failed to reach a settlement.

"After an earlier run at settling this case failed, the court observed that some cases just need to be tried," the court docket reads. "This case apparently needs to be tried twice. However unsuccessful, the court appreciates the parties' settlement efforts earlier today — especially those of Ms. Catz and Mr. Pichai."
