Apple is again being sued by what appears to be a patent troll, this time for an obvious patent for 2-step authentication which is now used by most banks and other tech firms for access to secure accounts. Patent was granted October 9, 2012 with an application date of September 14, 2007. My viewpoint is that 2-factor or 2-step authentication is obvious, an extension of what banks and other companies have done for years, e.g. calling to confirm charging on large transactions, but just automated. That makes it an obvious and easy extension of existing art that anyone in the industry would come up with. . . and did. — PING!

Dayglored, Shadow Ace: Ping for your lists as well since Android and Windows also use two-step and two-factor authentication, as do most banks, Google, and a host of other tech companies. It will be just a matter of time before this TROLL files shotgun suits against all of them as well.
