In the quickest patent to issue so far this year (by my calculation), Intermune, Inc. has been granted U.S. Patent No. 7,566,729 for "Modifying pirfenidone treatment for patients with atypical liver function". The claims appear to cover particular dosing method of administering pirfenidone to treat a patient with idiopathic pulmonary fibrosis.  Just under 100 days from filing (April 22, 2009) to issuance (July 28, 2009). That's Accelerated Examination in action.

A runner-up, at just over 100 days, goes to Perfect Pushup.  Yes, that Perfect Pushup, whose commercials you've certainly seen if you have ever watched ESPN for more than a few minutes.  It seems that one of the inventors is over 65, and the company wisely has filed Petitions to Make Special to jump to the front of the line.  Their fourth utility patent, U.S. Patent No. 7,566,292 issued today for a Handle Assembly for Use With an Exercise Bar. All of their utility patents appear to have had quick prosecutions: their longest filing-to-issuance has been 15 months, and the average is about 9.5.
