Does more volume mean deeper claims for Suzhou?
Each dot is one of Suzhou’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). Suzhou’s own 12.6 claims/patent is at or below the 17.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Suzhou's grants concentrate
Suzhou Zelgen Biopharmaceuticals Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 100% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2018. By volume, Suzhou sits between Sumitomo Pharma Oncology, Inc. and Switchboard Visual Technologies, Inc..
Suzhou's three-year grant acceleration
Suzhou Zelgen Biopharmaceuticals Co., Ltd. shows 1 grants in 2022–2024 against only 4 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.
