What this shows Suzhou's Innovation Score is 30.7/100 (35th 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 10.8 claims/patent is at or below the 14.6 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 Cleva Electric Appliance Co., Ltd is a focused PatentsView assignee: 15 CPC subclasses with 33.3% of grants classified under A47L (Domestic Washing OR Cleaning ; Suction Cleaners IN General). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2020. By volume, Suzhou sits between Sturm Maschinen- & Anlagenbau GMBH and SWM International, LLC.

Suzhou's three-year grant acceleration

Suzhou Cleva Electric Appliance 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.
