ppubs is the uspto’s granted patent searching screen. It slices, dices and lets you make simple or complex queries. What I would like would be for the uspto to provide all the underlying bulk data available to the publlic. They have made a staggering amount data available, but naturally in doing so they have left me wanting more! I dream of winning a contest where I get access to the uspto’s database for a little while- like those contests where someone gets to run through a department store grabbing what they can in the time allowed.
