Comparison of CBM and PGR Petitions
Over the last several months, Rowan has examined both Covered Business Method (CBM) and Post Grant Review (PGR) petitions, the times that 112 arguments were raised within them, and ultimately the frequency of one or more claims being canceled due to such arguments.
We thought it would be useful to wrap up this series by comparing the number of CBM and PGR petitions over time, to see the trends in when each was utilized. CBM filings were opened on September 16, 2012, and because it was always intended as a transitional program, the sunset of the program was 8 years later, on September 16, 2020.
The PGR program was also initiated on September 16, 2012, and continues today.
If we look at the number of CBM petitions during the program’s tenure, we see a rapid increase, and then a steady decline from 2015 to 2018, ultimately dying out in 2020 when the program terminated.
