Oracle has been willfully infringing on Thought's intellectual property "on a massive scale," the complaint states. Infringing products include Oracle WebLogic Server version 10.3.0 and later; Oracle TopLink version 10.1.3.5 and later; and all versions of Glassfish Server, among others, it states.
The plaintiffs are asking for an injunction against Oracle as well as unspecified compensatory damages.
An Oracle spokeswoman declined to comment on Thought's allegations on Wednesday.
It's not likely the case will receive as much attention as Oracle's lawsuit against Google over alleged Java patent and copyright violations in the Android mobile OS, which has captivated the tech industry for the past couple of years. Google largely prevailed in the case but Oracle is appealing.
