PageRank as a secret sauce that solves search -- this was actually always an overblown myth created in the early days of Google for PR purposes. It fits their PR mission perfectly because they want everyone to think that super smart algorithms are the secret to their success.
If PageRank was really as useful as they say, Google would have had tons of high-quality competitors from day 1.

It's easy to see how they could just go ahead and use the patented methods on their private servers, and no one on the outside would be able to legally prove that they copied their patented method, at least for a long time. Just some patents would never have kept competitors from moving in on this 200B market.
