Based on a today’s count, the PTAB Patent Review Processing System (PRPS) is now showing 34 petitions for patent review.  There are 10 pending petitions for covered business-method (CBM) patent review and 24 petitions for inter partes review (IPR).

What is confusing is that the PRPS system is assigning Trial Numbers that have changed from a prefix of IPR2012 to IPR2013 in recent days (and the prefix of CBM2012 has shifted to CBM2013 recently, as well).  It is not clear if this was an intended change or a software issue, but appears to be observed as PRPS original filing dates shifted from September filing dates to October filing dates.  It will be interesting to see if these matters are reassigned a 2012 prefix in the future.

So far, the new petitioners in October include Micron Technology, Inc. and Kyocera Corporation.   Additional petitions were filed by Illumina Inc. and by Liberty Mutual.
