Does more volume mean deeper claims for Celator?

Each dot is one of Celator’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). Celator’s own 14.6 claims/patent is at or below the 18.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Celator's grants concentrate

Celator Pharmaceuticals, Inc. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2016. By volume, Celator sits between Calderco Holdings Group, LLC and Certinia Inc..

Celator's three-year grant acceleration

Celator Pharmaceuticals, Inc. shows 5 grants in 2022–2024 against only 7 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.
