What this shows Hangzhou's Innovation Score is 31.3/100 (top 63% 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 Hikmicro Sensing Technology Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 60% of grants classified under H04N (PICTORIAL COMMUNICATION, e.g. TELEVISION). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2020. By volume, Hangzhou sits between Guangzhou Lianrou Machinery & Equipment Co., Ltd. and Hconnect 2 Gmbh.
Hangzhou Hikmicro Sensing Technology Co., Ltd. shows 3 grants in 2022–2024 against only 5 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.
