What this shows Chen's Innovation Score is 33.3/100 (44th 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 Chen?

Each dot is one of Chen’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). Chen’s own 10.8 claims/patent is ABOVE the 8.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Chen's grants concentrate

Chen Sound Industrial Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 88.9% of grants classified under B23Q (Details, Components, OR Accessories FOR Machine Tools, e.g. Arrangements FOR Copying OR Controlling ; Machine Tools IN General Characterised BY THE Construction OF Particular Details OR COMPONENTS; Co). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2015. By volume, Chen sits between Chaossearch, Inc. and China National Research Institute OF Food & Fermentation Industries Co., Ltd..

Chen's three-year grant acceleration

Chen Sound Industrial Co., Ltd. shows 4 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.
