The USPTO recently published updated statistics for filings under the AIA’s new post-grant procedures. As of November 2013, just 14 months after the new post grant challenges went into effect, the USPTO has received over 700 total petitions. The vast majority of them are for inter partes review (IPR), over 600 petitions, although there continues to be a steady filing of petitions for covered business method patents. Of note, 22 covered business method (CBM) reviews were filed in fiscal year 2014 alone. This is already about half of the total number of CBM requests filed for all of fiscal year 2013.
