The Patent Trial and Appeal Board issued 29 IPR and CBM Final Written Decisions in October, including decisions following remands from the Federal Circuit, cancelling 395 (79.80%) instituted claims while declining to cancel 100 (20.20%) instituted claims. Patent owners did not concede any 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 17 (58.62%) decisions, all instituted claims survived in 6 (20.69%) decisions, and a mixed outcome occurred in 6 (20.69%) 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.

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