Third party support firm Rimini Street has countersued Oracle, alleging copyright misuse, defamation, disparagement, trade libel and unfair competition under the California Business and Professions Code.
Oracle sued Rimini Street in January, accusing it of "massive theft of Oracle's software" and claiming that Rimini Street used automated software to download proprietary data from Oracles tech support sites.
Rimini Street now alleges: "Oracle and its predecessors began a systematic campaign to disrupt and halt Rimini Street's business since the inception of the company in 2005. As Rimini Street's success grew, so did Oracle's apparent determination and efforts to disrupt Rimini Street's growth."
Oracle said that it remains: "committed to customer choice and vigorous competition, but draws the line with any company, big or small, that steals its intellectual property."
In its most recent earnings report, Oracle said that license update and support revenue in the quarter ended in February rose 13% to $3.3 billion, or 60% of the company's total revenue in the period.
Rimini CEO Seth Ravin founded the company in 2005 after selling an equivalent company called TomorrowNow that supported PeopleSoft products.
