Legal 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'.

The main reason why devs don't try to invalidate more patents is their company won't let them. To invalidate a patent, you have to read it. If you read a patent and CANNOT invalidate it, you may now be in willful infringement, which triples the damages. So companies enact rules for devs, the main one being DON'T READ ANY PATENTS, EVER!! They recognize that any substantial program violates thousands of patents, and willful infringement could put them out of business.
