Joel Spolsky killed a Microsoft patent application in just a few minutes – he found prior art and submitted it, and the USPTO examiner rejected the patent because of it. “Micah showed me a document from the USPTO confirming that they had rejected the patent application, and the rejection relied very heavily on the document I found. This was, in fact, the first ‘confirmed kill’ of Ask Patents, and it was really surprisingly easy. I didn’t have to do the hard work of studying everything in the patent application and carefully proving that it was all prior art: the examiner did that for me.” This is all under the umbrella of ‘Ask Patents‘.
