Does more volume mean deeper claims for Shijiazhuang?

Each dot is one of Shijiazhuang’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). Shijiazhuang’s own 13.4 claims/patent is ABOVE the 10.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Shijiazhuang's grants concentrate

Shijiazhuang Yiling Pharmaceutical Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 88.9% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2016. By volume, Shijiazhuang sits between Shenzhen Tuozhu Technology Co., Ltd. and Shurtech Brands LLC.

Shijiazhuang's three-year grant acceleration

Shijiazhuang Yiling Pharmaceutical Co., Ltd. shows 5 grants in 2022–2024 against only 2 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.
