New Facebook lawyer Ted Ullyot will have his hands full. Before Mark Zuckerberg came along, every college had a facebook — a collection of pictures of the incoming freshman class, distributed in print. But now, there's only one Facebook. Aaron Greenspan, a Harvard student who came up with an online facebook called HouseSystem prior to the creation of Facebook, has long disputed Zuckerberg's claim to the idea — and he's been disputing the company's name, too. Records from the U.S. Patent and Trademark Office now show that Greenspan's suit to cancel Facebook's trademark has resumed, having survived two motions to dismiss. The most probable outcome here: Like Cameron and Tyler Winklevoss, the twins who claim they hired Zuckerberg to work on their college social network, ConnectU, Greenspan will get paid off with a piece of Facebook, too.
