What this shows Hangzhou's Innovation Score is 49.7/100 (top 14% 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 TARO Positioning Technology Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 81.8% of grants classified under H04N (PICTORIAL COMMUNICATION, e.g. TELEVISION). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2020. By volume, Hangzhou sits between H2o.ai Inc. and HAWE Altenstadt Holding Gmbh.
Hangzhou TARO Positioning Technology Co., Ltd. shows 7 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.
