For the past year, Dr. Tu, a former patent attorney with Foley & Lardner, has conducted a massive empirical examination of patent prosecution. Massive, in the sense that Dr. Tu and his assistants examined the prosecution behavior of every patent issued in the last ten years. In Luck/Unluck of the Draw: An Empricial Study of Examiner Allowance Rates, available at http://papers.ssrn.com/sol3/papers.cfm?abstract_id=1939508 and forthcoming in the Stanford Technology Law Review, Dr. Tu discusses some of the findings from his study. - Jason
