Does more volume mean deeper claims for Hunan?

Each dot is one of Hunan’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). Hunan’s own 8.8 claims/patent is at or below the 11.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Hunan's grants concentrate

Hunan Vathin Medical Instrument Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 66.7% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2022. By volume, Hunan sits between HUA Hong Semiconductor (WUXI) Limited and Hydac Filter Systems GMBH.

Hunan's three-year grant acceleration

Hunan Vathin Medical Instrument Co., Ltd. shows 6 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.
