Inter Partes Review: Overview and Statistics

When a patent is challenged by an IPR the challenge must be taken very seriously. Patent Office statistics for FY 2013 and FY 2014 through January 31, 2014, show that there have been a total of 361 decisions on IPR petitions, with 288 trials instituted. There have been 11 cases that have been joined and only 62 petitions denied, which corresponds with an 82.8% IPR petition grant rate. Having said this, the IPR grant rate during FY 2013 was 87.2%, while so far during FY 2014 the IPR grate rate has been 77.2%. This drop in IPR granting rate, while statistically relevant, should not lull patent owners into a false sense of security.
