This blog post is at three months past September 16, 2012, the date upon which the PTAB began accepting petitions for inter partes review and covered business method patent review under the America Invents Act.  Considering that there are about 15 CBM and 79 IPR petitions currently on file, the PTAB is getting petitions at the rate of roughly 1 per day.  That’s a very steady stream of work for the PTAB.  Here are the companies that have filed petitions as of the time of this post:

This is an impressive list of petitioners.  Many have multiple filings, and some have a large number of filings.  For example, Chi Mei Innolux has 7 filings, Corning Inc. has 10 filings, and Liberty Mutual has 10 filings.  Now that we are coming upon the three month mark, patent owner preliminary responses will be filed.  In the coming months, the PTAB will be deciding whether to institute trials and disovery will begin in several cases.
