The PTAB has posted the AIA Trial Statistics through the end of calendar year 2017.  The PTAB statistics are available for download at the PTO website.

Petition filings remained high with 1799 total petitions for review filed, compared with 1758 in 2016 and 1798 in 2015.

Most notably, the statistics show a continued downward trend in institution rates, currently at 59%.

Also noteworthy is the continued lack of PGR filings, with only 86 PGR filings (compared to 7311 IPRs and 533 CBMs).
