JUST THE STATS:
PHARMA IPR: SURVIVAL RATE OF INSTITUTED CLAIMS

Key Finding:

This chart shows the survival rate of instituted claims in pharmaceutical IPR proceedings that reached a final written decision. While survival rate drops by roughly half compared to pre-institution pharmaceutical cases, the post-institution survival rate shown here (about 49%) is significantly higher than the overall post-institution survival rate for IPR proceedings across all technology areas (about 22%). This analysis does not factor in challenges that did not reach a decision on the merits because of settlement, or redundancies (which were deemed immaterial).
