What this shows Chuan's Innovation Score is 29.6/100 (31st 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 Chuan?

Each dot is one of Chuan’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). Chuan’s own 5.8 claims/patent is at or below the 9.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Chuan's grants concentrate

Chuan Jiing Enterprise Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 16.7% of grants classified under F16D (Couplings FOR Transmitting ROTATION; CLUTCHES; Brakes). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2015. By volume, Chuan sits between Cherry GMBH and CJ E&M Corporation.

Chuan's three-year grant acceleration

Chuan Jiing Enterprise Co., Ltd. shows 2 grants in 2022–2024 against only 3 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.
