Does more volume mean deeper claims for Epirium?

Each dot is one of Epirium’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). Epirium’s own 16.8 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 Epirium's grants concentrate

Epirium Bio Inc. is a focused PatentsView assignee: 4 CPC subclasses with 80% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2020. By volume, Epirium sits between Eonite Perception Inc. and Equinox Ophthalmic, Inc..

Epirium's three-year grant acceleration

Epirium Bio Inc. shows 2 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.
