What this shows Hangzhou's Innovation Score is 20.8/100 (7th 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 Hangzhou?

Each dot is one of Hangzhou’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). Hangzhou’s own 3.2 claims/patent is at or below the 11.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Hangzhou's grants concentrate

Hangzhou Fufan Industry Co., Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 40% of grants classified under A01K (Animal HUSBANDRY; AVICULTURE; APICULTURE; PISCICULTURE; FISHING; Rearing OR Breeding Animals, NOT Otherwise Provided FOR; NEW Breeds OF Animals). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2021. By volume, Hangzhou sits between Groundspeak, Inc. and Hangzhou Virtual AND Reality Technology Co., Ltd..

Hangzhou's three-year grant acceleration

Hangzhou Fufan Industry Co., Ltd. shows 4 grants in 2022–2024 against only 6 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.
