Between the previous dated page (June 12, 2014) and July 10, 2014, 171 petitions were filed, 57 trials were instituted, 32 petitions were denied institution and 23 final written decisions issued. The cumulative institution rate moved from 71.6% to 70.9%.

Trial Types Covered

1,488 of the 1,682 petitions (88.5%) were for inter partes review, which challenges patent claims on prior-art grounds under 35 U.S.C. chapter 31. The remainder were for covered business method review (189), post-grant review under chapter 32 (0) and derivation proceedings (5). Institution standards differ by proceeding; see the threshold standards.

How These Figures Were Compiled

The figures are counted from USPTO Open Data Portal records retrieved on October 31, 2026, keeping only events dated on or before July 10, 2014: a petition by its filing date, an institution decision by its decision date, and a final written decision or termination by its date. They are a reconstruction from the current records, not the USPTO’s report of that date, and may differ from statistics the USPTO published at the time. Final written decision outcomes are not reported because the records state them for too few decisions. The methodology gives the counting rules in full.
