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 4.8 claims/patent is at or below the 11.5 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 Zhonghai Pharmaceutical Co. Ltd is a focused PatentsView assignee: 2 CPC subclasses with 100% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2022. By volume, Shandong sits between Shandong Academy OF Agricultural Machinery Sciences and Shanghai Henlius Biotech, Inc..
Shandong's three-year grant acceleration
Shandong Zhonghai Pharmaceutical Co. Ltd shows 1 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.
