What this shows Chien's Innovation Score is 39.9/100 (top 37% 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 Chien?

Each dot is one of Chien’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). Chien’s own 15.1 claims/patent is at or below the 16.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Chien's grants concentrate

Chien Luen Industries Co., Ltd., Inc. is a focused PatentsView assignee: 22 CPC subclasses with 50% of grants classified under F04D (Non-positive-displacement Pumps). Peak complete grant year is 2015 (7 grants) versus a trough of 2 in 2021. By volume, Chien sits between Canon Information and Imaging Solutions, Inc. and ContiTech USA, Inc..

Chien's three-year grant acceleration

Chien Luen Industries Co., Ltd., Inc. shows 3 grants in 2022–2024 against only 10 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.
