Well, that would take a lawyer (or somebody skilled in reading patents) to say, after reading it carefully-- which isn't something you can do quickly. This patent was filed in 2008, but it is a continuation of a patent filed in 2004, which was split off from another patent filed in 2004, which was a continuation of a patent filed in 1999, which was a continuation of a patent filed in 1997. In other words, it is possible that there are claims here that predate any of Facebook's prior art-- but that would depend upon the specific claims in the prior patents.
