What this shows Suzhou's Innovation Score is 34.1/100 (47th percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

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 11.1 claims/patent is ABOVE the 10.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Suzhou's grants concentrate

Suzhou Pengxu Pharmatech Co. Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 100% of grants classified under C07D (Heterocyclic Compounds). Peak complete grant year is 2018 (2 grants) versus a trough of 1 in 2017. By volume, Suzhou sits between Suss Microtec Photomask Equipment GMBH & Co and Synerscope B.V..

Suzhou's three-year grant acceleration

Suzhou Pengxu Pharmatech Co. Ltd. shows 4 grants in 2022–2024 against only 3 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.
