The Patent Trial and Appeal Board issued 27 IPR and CBM Final Written Decisions in December, including decisions following remands from the Federal Circuit, cancelling 292 (70.19%) instituted claims while declining to cancel 104 (25.00%) instituted claims. Patent owners conceded 20 (4.81%) instituted claims through motions to amend or disclaimer in cases reaching a final decision. For comparison, the cumulative average rate of instituted claims cancelled in IPR and CBM Final Written Decisions is about 74%.

On a per-case basis, no instituted or substitute claims survived in 12 (44.44%) decisions, all instituted claims survived in 10 (37.04%) decisions, and a mixed outcome occurred in 5 (18.52%) decisions. A mixed outcome occurs where at least one instituted or substitute claim remains patentable, and at least one is cancelled, in a Final Written Decision.

Interestingly, the Board in December granted 72 substitute claims in motions to amend out of the 117 proposed substitute claims it considered in IPRs and CBMs, a grant rate of 61.54%. The cumulative substitute claim grant rate remains relatively low at 12.79%.

The overall cumulative instituted claim survival rate, broken down by technology center, is as follows:
