What this shows Chung-hsin'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 Chung-hsin?

Each dot is one of Chung-hsin’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). Chung-hsin’s own 14.0 claims/patent is ABOVE the 12.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Chung-hsin's grants concentrate

Chung-hsin Electric &machinery MFG. Corp. is a focused PatentsView assignee: 9 CPC subclasses with 87.5% of grants classified under H02J (Circuit Arrangements OR Systems FOR Supplying OR Distributing Electric POWER; Systems FOR Storing Electric Energy). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2019. By volume, Chung-hsin sits between CHR.MAYR GMBH + Co. KG and Cireca Theranostics, LLC.

Chung-hsin's three-year grant acceleration

Chung-hsin Electric &machinery MFG. Corp. shows 1 grants in 2022–2024 against only 1 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.
