JUST THE STATS:
PHARMA IPR: BREAKDOWN BY CLAIM AND CHALLENGE TYPES AND UNPATENTABILITY RATE OF CHALLENGED CLAIMS

Key Finding: This chart presents the percentage of claims found unpatentable under Sections 102 and 103 for the different categories of pharmaceutical claims, out of the claims originally challenged. Compound claims were found unpatentable more often under Section 102. However, for composition claims, the opposite held true. The low level of success for obviousness attacks against compound claims may be a reason for the overall low success rate of challenges against those claims.
