What this shows Dong's Innovation Score is 39.8/100 (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 Dong?

Each dot is one of Dong’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). Dong’s own 12.7 claims/patent is ABOVE the 8.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Dong's grants concentrate

Dong HEE Industrial Co., Ltd. is a focused PatentsView assignee: 18 CPC subclasses with 45% of grants classified under G05G (Control Devices OR Systems Insofar AS Characterised BY Mechanical Features Only). Peak complete grant year is 2016 (4 grants) versus a trough of 2 in 2017. By volume, Dong sits between Digital Reasoning Systems, Inc. and Dalen Products, Inc..

Dong's three-year grant acceleration

Dong HEE Industrial Co., Ltd. shows 4 grants in 2022–2024 against only 4 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.
