Yes I chose my use of "apparently" and "if this is true" carefully. There is another widely reported instance, better known as Meta PC, filing before Facebook for the mark "Meta", covering "Computers, laptops and portable computers, tablets, computer peripherals, servers, networking equipment, software, computer components, namely, ram, disk drives, namely, hard and optical disk drives, and all related accessories, namely, keyboards, mice, wireless keyboards and mice, speakers, external hard drive backup devices, wireless air cards, wireless routers, monitors, chairs". This is indeed live on the USPTO search right now. That to me sounds like a potential problem.
Not if you have Zuck's Fuck You money financing the cause. Your potential problem just became billable hours for the Army of the Damned-Lawyers.
