"The Patent Examiner blog has the incredible story of Innovatio IP, a patent troll that recently acquired a portfolio of patents that its lawyers (what, you think there are any employees?) appear to believe cover pretty much any Wi-Fi implementation. They've been suing coffee shops, grocery stores, restaurants and hotels first — including Caribou Coffee, Cosi, Panera Bread Co, certain Marriotts, Best Westerns, Comfort Inns and more. ... The lawyer representing the company, Matthew McAndrews, seems to imply that the company believes the patents cover everyone who has a home Wi-Fi setup, but they don't plan to go after such folks right now, for 'strategic' reasons."
