What this shows Suzhou's Innovation Score is 49.2/100 (top 15% 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 10.1 claims/patent is at or below the 11.1 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 University OF Science AND Technology is a focused PatentsView assignee: 17 CPC subclasses with 36.4% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). Peak complete grant year is 2023 (3 grants) versus a trough of 2 in 2022. By volume, Suzhou sits between Suzhou Alton Electrical & Mechanical Industry Co., Ltd. and Synova S.A..

Suzhou's three-year grant acceleration

Suzhou University OF Science AND Technology shows 7 grants in 2022–2024 against only 0 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.
