Does more volume mean deeper claims for Hefei?

Each dot is one of Hefei’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). Hefei’s own 7.2 claims/patent is at or below the 9.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Hefei's grants concentrate

Hefei CAS ION Medical AND Technical Devices Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 66.7% of grants classified under H05H (Plasma Technique ; Production OF Accelerated Electrically-charged Particles OR OF NEUTRONS; Production OR Acceleration OF Neutral Molecular OR Atomic Beams). Peak complete grant year is 2019 (3 grants) versus a trough of 2 in 2020. By volume, Hefei sits between Heat AND Control, Inc. and Hero Scientific Ltd..

Hefei's three-year grant acceleration

Hefei CAS ION Medical AND Technical Devices Co., Ltd. shows 2 grants in 2022–2024 against only 7 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.
