"As part of Google's mission to organize the world's information and make it universally accessible and useful, we're constantly working to expand the diversity of content we make available to our users. With Google Patents, you can now search the full text of the U.S. patent corpus and find patents that interest you."
Google has had its own issues with patents. Like much of the rest of the software industry, it avoided filing for them for some years, but competitive patenting has taken over the industry in the drive to gain a monopolistic advantage or prevent others from doing so by establishing a patent pool to force cross licensing. By making it easier to challenge applications and even granted patents, putting them on line should make bad patents rarer. The problem of identifying and proving prior art remains.
