McGruber writes "Gigaom's Jeff John Roberts reports that Martha Stewart Living Omnimedia, Inc. (MSLO) has filed a lawsuit against Lodsys, a shell company that gained infamy two years ago by launching a wave of legal threats against small app makers, demanding they pay for using basic internet technology like in-app purchases or feedback surveys. In the complaint filed this week in federal court in Wisconsin, Martha Stewart Living Omnimedia asked a judge to declare that four magazine iPad apps are not infringing Lodsys' patents, and that the patents are invalid because the so-called inventions are not new. The complaint explained how Lodsys invited the company to 'take advantage of our program' by buying licenses at $5,000 apiece. It also calls the Wisconsin court's attention to Lodsys' involvement in more than 150 Texas lawsuits. In choosing to sue Lodsys and hopefully crush its patents, Martha Stewart is choosing a far more expensive option than simply paying Lodsys to go away."
