Does more volume mean deeper claims for Etablissement?

Each dot is one of Etablissement’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). Etablissement’s own 12.5 claims/patent is at or below the 17.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Etablissement's grants concentrate

Etablissement Francais DU Sang (EFS) is a focused PatentsView assignee: 17 CPC subclasses with 48.3% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2022 (6 grants) versus a trough of 1 in 2018. By volume, Etablissement sits between Ecole Normale Superieure and EnGeneIC Molecular Delivery Pty Ltd.

Etablissement's three-year grant acceleration

Etablissement Francais DU Sang (EFS) shows 15 grants in 2022–2024 against only 5 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.
