What this shows Suzhou's Innovation Score is 32.8/100 (42nd 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 22.2 claims/patent is ABOVE the 9.2 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 Ruifa Printing Technology Co. Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under B41J (TYPEWRITERS; Selective Printing Mechanisms, i.e. Mechanisms Printing Otherwise Than From A FORME; Correction OF Typographical Errors). By volume, Suzhou sits between Sustainable Oils, Inc. and Sweetspot Baseball, LLC.

Suzhou's three-year grant acceleration

Suzhou Ruifa Printing Technology Co. Ltd. shows 3 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.
