Or, he filed the patent years ago, and then filed a series of updates to it. Each update delays the final "approval date" and allows him to modify the patent. Over time, he can craft a vague sounding patent and/or one that covers existing technology. Then, his "prior art date" is from a year before when he INITIALLY filed the patent. So while the final patent might have been considered innovative if filed as-is on the initial filing date, patent trolls abuse the "update" system to draw their patents out until they are hard to beat via prior art.
Or, even more likely, the patent examiners said "We'll approve this and let the courts sort it out." Meanwhile, the courts are likely to say "Well, the patent examiners wouldn't have approved this if it wasn't a valid patent."
