The US Court of Appeals has slashed the amount Rimini Street owes Oracle as the pair's bitter feud rumbles on.
Numerous lawsuits over recent years have led to Rimini Street, an independent support provider of Oracle products, racking up a bill of around $124m (£92m) after being found to have infringed Oracle's copyright.
The latest ruling, according to Rimini Street, will see around $50m taken off the total amount owed to Oracle.
In a statement Rimini Street said: "Today, the Court of Appeals reversed certain awards made in Oracle's favour during and after our 2015 trial, and vacated others, including an injunction that had already been stayed by the appellate court.
"Rimini Street should eventually receive a refund of up to nearly $50m of the judgment previously paid by Rimini Street to Oracle."
Oracle was also chasing Rimini Street CEO Seth Ravin personally for $14m, which Rimini Street said has been scrapped by the court.
The Court of Appeals said that Rimini Street now provides third-party support "in lawful competition against Oracle", the vendor stated, before adding that it will continue to pursue Oracle for separate claims.
Oracle was equally confrontational, and in a statement said: "We are pleased that the Court of Appeals affirmed the judgment on Rimini Street's infringement of all 93 of Oracle's copyrights in this case.
"Copyright infringement is at the core of Oracle's dispute with Rimini, and [the] Court of Appeal [has] affirmed all of the trial court's and the jury's findings that Rimini blatantly violated copyright law.
"We look forward to the trial court issuing a permanent injunction against Rimini for its egregious and illegal conduct."
