Free the Patents

A pretty silly title, really. Patents are already free at the USPTO site. However, there are advantages to searching a site like FreePatentsOnline (http://www.freepatentsonline.com/). One advantage is the sheer speed of the search engine. When I searched the site for recent ChevronMobil patents containing the key words DESULFURIZATION or DIBENZOTHIOPHENE, it took me longer to type in the search statement (below) than it took the search engine to return the results (reproduced below).
