What this shows Hangzhou's Innovation Score is 20.8/100 (top 93% 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.
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 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.
