What this shows Chi's Innovation Score is 30.7/100 (35th 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 Chi?

Each dot is one of Chi’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). Chi’s own 5.7 claims/patent is at or below the 13.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Chi's grants concentrate

Chi Hua Fitness Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 82.4% of grants classified under A63B (Apparatus FOR Physical Training, Gymnastics, Swimming, Climbing, OR FENCING; Ball GAMES; Training Equipment). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2017. By volume, Chi sits between Centre Hospitalier Regional Universitaire de Montpellier and ChromaDex Inc..

Chi's three-year grant acceleration

Chi Hua Fitness Co., Ltd. shows 5 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.
