What this shows Cairdac's Innovation Score is 41.7/100 (top 33% 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.

Where Cairdac's grants concentrate

Cairdac is a focused PatentsView assignee: 8 CPC subclasses with 96% of grants classified under A61N (ELECTROTHERAPY; MAGNETOTHERAPY; Radiation THERAPY; Ultrasound Therapy). Peak complete grant year is 2021 (7 grants) versus a trough of 1 in 2020. By volume, Cairdac sits between Brelyon Inc and Chung Chwan Enterprise Co., Ltd..

Cairdac's three-year grant acceleration

Cairdac shows 15 grants in 2022–2024 against only 8 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.
