The Patent Trial and Appeal Board issued 34 IPR, CBM, and PGR Final Written Decisions in April, including decisions following remands from the Federal Circuit, cancelling 230 (69.49%) instituted claims while maintaining the patentability of 101 (30.51%) 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, CBM, and PGR Final Written Decisions is about 73%.
On a per-case basis, no instituted or substitute claims survived in 17 (50%) decisions, all instituted claims survived in 8 (23.53%) decisions, and a mixed outcome occurred in 9 (26.47%) 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.
In May, the PTAB issued 18 IPR, CBM, and PGR Final Written Decisions, cancelling 198 (76.15%) instituted claims while maintaining the patentability of 62 (23.85%) instituted claims. Patent owners again did not concede any claims through motions to amend or disclaimer in cases reaching a final decision.
On a per-case basis, no instituted or substitute claims survived in 13 (72.22%) decisions, all instituted claims survived in 4 (22.22%) decisions, and a mixed outcome occurred in 1 (5.56%) decision.
The overall cumulative instituted claim survival rate in IPRs, CBMs, and PGRs, broken down by technology center, is as follows:
