What this shows Calb's Innovation Score is 50.9/100 (top 12% 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 12.8 claims/patent is at or below the 13.5 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 Technology Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 100% 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 2023 (8 grants) versus a trough of 2 in 2022. By volume, Calb sits between Bripco Bvba and Catheter Precision, Inc..

Calb's three-year grant acceleration

Calb Technology Co., Ltd. shows 17 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.
