Does more volume mean deeper claims for Anhui?

Each dot is one of Anhui’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). Anhui’s own 8.8 claims/patent is at or below the 16.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Anhui's grants concentrate

Anhui New Star Pharmaceutical Development Co., Ltd is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under C07D (Heterocyclic Compounds). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2021. By volume, Anhui sits between Anchor Innovation Medical, Inc. and Anji Microelectronics (Shanghai) Co. Ltd.

Anhui's three-year grant acceleration

Anhui New Star Pharmaceutical Development Co., Ltd shows 1 grants in 2022–2024 against only 1 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.
