Patent on searching books online

An interesting patent granted last week on searching books. I would have thought to see something like this from Amazon, or maybe even Google. But it isn’t.

Method and system for full text search of purchasable books that make the full text inaccessible to users

The patent does refer to a New York Times article from July 23, 2003 about Amazon.com’s Look inside the Book process: Amazon Plan Would Allow Searching Texts of Many Books

Any implications for Google Book Search or Amazon’s Search Inside the Book? I’m not sure. I’m guessing not. But, keep your eyes open just in case.
