Dennis Crouch

In 1997, he received his B.S.E. in Mechanical and Aerospace Engineering from Princeton University, where he also earned a certificate in engineering management systems. In 2003, he received his J.D. from the University of Chicago Law School, and passed the Illinois bar examination and was admitted to practice in Illinois in the same year. He also passed the USPTO registration examination, most likely in 2003, and was registered to practice as a patent agent in February 2004 and as a patent attorney in August 2004. He runs the "Patently-O Patent Blog", a patent law blog that features analysis on current Federal Circuit law and other subjects. According to BusinessWeek, as of 2008 the Patently-O blog was the most widely read patent law blog and was included in the American Bar Association Journal blog's inaugural patent blog "hall of fame" in 2012. Crouch is reported to be "fairly obsessive about timeliness, checking the Federal Circuit's site when it is updated each morning and immediately noting new cases on his blog."
