What this shows Chio's Innovation Score is 32.6/100 (42nd percentile 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 Chio?

Each dot is one of Chio’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). Chio’s own 15.2 claims/patent is ABOVE the 12.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Chio's grants concentrate

CHiO Kang Medical, Inc. is a focused PatentsView assignee: 14 CPC subclasses with 56.3% of grants classified under A61L (Methods OR Apparatus FOR Sterilising Materials OR Objects IN GENERAL; Disinfection, Sterilisation OR Deodorisation OF AIR; Chemical Aspects OF Bandages, Dressings, Absorbent Pads OR Surgical ARTICLES;). Peak complete grant year is 2021 (15 grants) versus a trough of 1 in 2022. By volume, Chio sits between Cheng Shin Rubber IND. Co., Ltd. and CMP Products Limited.

Chio's three-year grant acceleration

CHiO Kang Medical, Inc. shows 1 grants in 2022–2024 against only 15 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.
