What this shows Carewear's Innovation Score is 38.5/100 (top 41% 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 Carewear?

Each dot is one of Carewear’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). Carewear’s own 32.4 claims/patent is ABOVE the 13.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Carewear's grants concentrate

Carewear Corp. is a focused PatentsView assignee: 10 CPC subclasses with 90% of grants classified under A61N (ELECTROTHERAPY; MAGNETOTHERAPY; Radiation THERAPY; Ultrasound Therapy). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2019. By volume, Carewear sits between Canon Marketing Japan Kabushiki Kaisha and Catry International Group, Inc..

Carewear's three-year grant acceleration

Carewear Corp. shows 3 grants in 2022–2024 against only 5 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.
