Lodsys has been facing an increasing backlash ever since it began suing left and right to scrape money from developers over patents, including countering lawsuits from some heavy hitters. Its stiffest opposition might have just lined up in the form of Oracle, however. The database behemoth is hoping to render four of Lodsys' patents invalid and prevent it from threatening further lawsuits against companies that use Oracle's technology, such as current target Walgreens. The lawsuits are focused more on web chats than on the in-app purchasing that has put more than a few mobile app developers in jeopardy, although it might help EA or Rovio at ease knowing Lodsys might be defanged. Oracle certainly isn't mincing any words in its accusations: it out-and-out accuses Lodsys of being a patent troll that profits from technology it didn't invent and will never use. Strong rhetoric against patent lawsuits won't guarantee Oracle a victory in court, but it certainly creates a minor degree of irony for a company that unsuccessfully sued Google over patents inherited through an acquisition.
