What this shows Hengdian's Innovation Score is 49.9/100 (top 14% 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 Hengdian?

Each dot is one of Hengdian’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). Hengdian’s own 15.9 claims/patent is ABOVE the 11.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Hengdian's grants concentrate

Hengdian Group Dmegc Magnetics Co., Ltd is a focused PatentsView assignee: 14 CPC subclasses with 42.9% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). By volume, Hengdian sits between Helix Co., Ltd. and Hexagon Manufacturing Intelligence Sarl.

Hengdian's three-year grant acceleration

Hengdian Group Dmegc Magnetics Co., Ltd shows 4 grants in 2022–2024 against only 0 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.
