On March 31, 2017, the United States Patent Trial and Appeal Board (“PTAB”) released updated statistics showing the fate of resolved inter partes review (“IPR”) proceedings. These statistics show that a total of 4,563 IPR petitions were resolved as of March 31, 2017 including 1,577 final written decisions. In 81% of these final written decisions (27% of the total number of petitions filed), at least some instituted patent claims were found unpatentable. This statistic has contributed to concerns that PTAB is a patent “death squad.”
Venable Fitzpatrick’s BiologicsHQ reports that such concern is not justified for drug patents. On the contrary, IPR statistics for this subset of patents are significantly more favorable: a smaller percentage of drug patent IPRs are instituted; and of those that reach a final written decision, a higher percentage of patents survive with at least some claims remaining patentable. This is welcome news to the pharmaceutical industry.
