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 9.2 claims/patent is at or below the 12.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Hengdian's grants concentrate

Hengdian Group Innuovo Electric Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 33.3% of grants classified under H02K (Dynamo-electric Machines). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2021. By volume, Hengdian sits between Hebei University OF Science AND Technology and Hexagon Geosystems Services AG.

Hengdian's three-year grant acceleration

Hengdian Group Innuovo Electric 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.
