Dispute Summary
A statistical study of 192 IPR final written decisions from 2021 shows that patents invalidated in IPR have far more prior‑art citations and often depend on new evidence such as expert testimony. The findings suggest that post‑grant challenges frequently introduce prior art outside the examiner’s original search scope.
