Does more volume mean deeper claims for Shandong?

Each dot is one of Shandong’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). Shandong’s own 11.7 claims/patent is at or below the 14.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Shandong's grants concentrate

Shandong Danhong Pharmaceutical Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 90% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2017. By volume, Shandong sits between Seoyon America Corporation and Shanghai Maritime University.

Shandong's three-year grant acceleration

Shandong Danhong Pharmaceutical Co., Ltd. shows 3 grants in 2022–2024 against only 5 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.
