What this shows Hangzhou's Innovation Score is 37.7/100 (top 43% 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 15.5 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 Hangzhou's grants concentrate
Hangzhou Qingqi Science AND Technology Co., Ltd. is a focused PatentsView assignee: 18 CPC subclasses with 66.7% of grants classified under H04W (Wireless Communication Networks). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2023. By volume, Hangzhou sits between Hangzhou Jingcheng Sanhe Timer Industry Co., Ltd. and Hanil E-hwa Co., Ltd..
Hangzhou's three-year grant acceleration
Hangzhou Qingqi Science AND 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.
