Trial Statistics from the Patent Trial & Appeal Board

By Eugene T. Perez

As of November 28, 2013, the Patent Trial and Appeal Board (“PTAB”) has updated the statistics of the number of inter partes reviews (“IPR”), post-grant reviews of covered business method patents (“CBM”), and derivation proceedings (“DER”) that have been filed. These stats are shown below. Previous statistics can also be found here.

The PTAB determines whether or not an IPR or PGR will be granted.  The PTAB may not authorize the IPR unless the petition and response shows there is a “reasonable likelihood” that the petitioner would prevail with at least one of the challenged claimed.[1] The granting of a PGR trial requires an initial threshold requirement of “more likely than not”, and is slightly higher than the IPR threshold standard. However, the latest statistics clearly show that the initial threshold has been met the majority of the time (see the AIA Trials Instituted/Disposals chart below).  The number of AIA Petitions, where 697 IPR petitions have been filed:

About 71% of the IPR and CBM petitions filed are in the electrical/computer arts, and less than 6% are in the biotechnology/pharma arts.  The petitions by technology breakdown are:

During an IPR or CBM, the Patent Owner (“PO”) can optionally file a Preliminary Response.[2]  Clearly, according to these statistics, the PO is choosing to file a Preliminary Response most of the time. The number of filed PO Preliminary Responses is in the next chart:
