New claim construction in IPR and PGR

While the rate of filings for a post-grant review (PGR) trial has been slow, the rate of petitions filed to request an inter partes review (IPR) or a PGR specifically for a covered business method (CBM) patent trial have exceeded expectations. The rate of granting PGRs is around 70% for the fiscal year 2015, although it was higher in previous fiscal years. Once instituted, the petitioner has succeeded in cancelling patent claims in more than 70% of cases.
