In February, the PTAB cancelled 397 (71.27%) instituted claims across 32 IPR and PGR Final Written Decisions, including decisions issued following remand from the Federal Circuit. After review, 151 (27.11%) instituted claims survived. Patent owners conceded 9 (1.62%) claims, such as through motions to amend the instituted claims. For comparison, the cumulative average cancellation rate of instituted claims in IPR, CBM, and PGR Final Written Decisions is about 74%.
On a per-case basis, no instituted or substitute claims survived in 20 (62.5%) decisions, all instituted claims survived in 4 (12.5%) decisions, and a mixed outcome occurred in 8 (25%) decisions.
