This page reports Patent Trial and Appeal Board trial activity in fiscal year 2014, which ran from October 1, 2013 to September 30, 2014. Each figure is a count of USPTO Open Data Portal records; the methodology on the statistics page explains the counting rules.

Figures by Trial Type

Petitions are counted by filing date. Institution decisions, final written decisions and terminations are counted by the date of the event, so a petition filed in one fiscal year may be decided in the next.

Figures by Trial Type in Detail

Inter Partes Review (IPR)

In FY2014, 1,310 IPR petitions were filed (87.7% of all AIA petitions). Of 868 IPR institution decisions, 562 instituted a trial and 306 denied institution, a rate of 64.7%. The Board issued 150 IPR final written decisions. An IPR may be instituted only on a reasonable likelihood that the petitioner will prevail on at least one claim (35 U.S.C. § 314(a)), on grounds of anticipation or obviousness over patents and printed publications. See the inter partes review guide for the procedure.

Post-Grant Review (PGR)

In FY2014, 2 PGR petitions were filed (0.1% of all AIA petitions). No PGR institution decisions were recorded. The Board issued 0 PGR final written decisions. A PGR petition must be filed within nine months of grant and must show that it is more likely than not that at least one claim is unpatentable (35 U.S.C. § 324(a)). See the post-grant review guide for the procedure.

Covered Business Method Review (CBM)

In FY2014, 177 CBM petitions were filed (11.9% of all AIA petitions). Of 143 CBM institution decisions, 93 instituted a trial and 50 denied institution, a rate of 65.0%. The Board issued 16 CBM final written decisions. CBM review applied to covered business method patents and closed to new petitions on September 16, 2020. See the covered business method review guide for the procedure.

Derivation Proceedings (DER)

In FY2014, 4 DER petitions were filed (0.3% of all AIA petitions). Of 3 DER institution decisions, 0 instituted a trial and 3 denied institution, a rate of 0.0%. The Board issued 0 DER final written decisions. Derivation proceedings decide whether an inventor named in an earlier application derived the claimed invention from the petitioner’s inventor; they are few in number, so rates rest on small counts. See the guide to the Patent Trial and Appeal Board for the procedure.

How Proceedings Ended

Of the proceedings that ended during the period, 166 ended in a final written decision under 35 U.S.C. § 318, 125 in settlement under 35 U.S.C. § 317, 0 in adverse judgment, 0 by dismissal and 7 by other termination. Denials of institution are counted separately above. A final written decision can lead to estoppel against the petitioner; see estoppel arising from PTAB trials.

Final written decision outcomes (all, some or no challenged claims unpatentable) are not reported because the USPTO records state them for too few decisions; see the methodology. Figures may differ from the USPTO’s published reports. For how trials end and why reported rates differ, see reading PTAB trial outcomes.
