What this shows Calb's Innovation Score is 56.4/100 (top 6% 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 Calb?

Each dot is one of Calb’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). Calb’s own 15.3 claims/patent is at or below the 16.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Calb's grants concentrate

Calb Co., Ltd. is a focused PatentsView assignee: 16 CPC subclasses with 93% of grants classified under H01M (Processes OR Means, e.g. Batteries, FOR THE Direct Conversion OF Chemical Energy Into Electrical Energy). Peak complete grant year is 2024 (17 grants) versus a trough of 4 in 2022. By volume, Calb sits between BioAtla, Inc. and Carbonite, Inc..

Calb's three-year grant acceleration

Calb Co., Ltd. shows 32 grants in 2022–2024 against only 0 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.
