What this shows Calagen's Innovation Score is 50.4/100 (top 13% 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 Calagen?

Each dot is one of Calagen’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). Calagen’s own 18.8 claims/patent is at or below the 19.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Calagen's grants concentrate

Calagen, Inc. is a focused PatentsView assignee: 13 CPC subclasses with 100% of grants classified under H02N (Electric Machines NOT Otherwise Provided FOR). Peak complete grant year is 2021 (3 grants) versus a trough of 2 in 2023. By volume, Calagen sits between Curbside Inc. and Canadian National Railway Company.

Calagen's three-year grant acceleration

Calagen, Inc. shows 8 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.
