It's easy to mock the little guy when he takes a handful of giant corporations to court. Such litigious overzealousness usually gets tangled up or tossed out altogether -- Klausner Technologies, however, is laughing all the way to the bank, with a stellar track record taking on some of tech's biggest names over the past few years. To date, the company has scored wins in visual voicemail patent battles with Apple, Google, Verizon, LG, and Vonage -- the company also struck a deal with Sprint, though presumably with less teeth-pulling. This week, Klausner added four more big wins to the list, inking deals with Panasonic, Yahoo, Qwest Communications, and Avaya in the wake of suits against the tech firms. The company still has ongoing battles with RIM and Cisco that will hopefully stay civil. We'd hate to see someone send a visual voicemail they'd regret later.
