What this shows Endo's Innovation Score is 35.7/100 (top 49% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Endo?

Each dot is one of Endo’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Endo’s own 28.3 claims/patent is ABOVE the 14.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Endo's grants concentrate

Endo Pharmaceuticals Inc. is a focused PatentsView assignee: 7 CPC subclasses with 76.9% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2022. By volume, Endo sits between Electric Power Research Institute, China Southern Power Grid and Eni-jr286, Inc..

Endo's three-year grant acceleration

Endo Pharmaceuticals Inc. shows 1 grants in 2022–2024 against only 3 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
