What this shows Celltrion's Innovation Score is 39.3/100 (top 39% 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 Celltrion?

Each dot is one of Celltrion’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). Celltrion’s own 12.3 claims/patent is at or below the 15.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Celltrion's grants concentrate

Celltrion Inc. is a focused PatentsView assignee: 16 CPC subclasses with 79.3% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2015. By volume, Celltrion sits between C4 Therapeutics, Inc. and CMC Materials LLC.

Celltrion's three-year grant acceleration

Celltrion Inc. shows 9 grants in 2022–2024 against only 10 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.
