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 14.8 claims/patent is at or below the 17.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Endo's grants concentrate

Endo Operations Limited is a focused PatentsView assignee: 8 CPC subclasses with 100% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). By volume, Endo sits between En-Fab Inc. and Energica Motor Company S.p.A..

Endo's three-year grant acceleration

Endo Operations Limited shows 2 grants in 2022–2024 against only 0 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.
