What this shows Hangzhou's Innovation Score is 47.8/100 (top 18% 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 7.4 claims/patent is at or below the 12.2 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 Ezviz Software Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 16.7% of grants classified under G06V (Image OR Video Recognition OR Understanding). Peak complete grant year is 2023 (11 grants) versus a trough of 1 in 2022. By volume, Hangzhou sits between Guangzhou On-Bright Electronics Co., Ltd. and Hitachi Data Systems Corporation.

Hangzhou's three-year grant acceleration

Hangzhou Ezviz Software Co., Ltd. shows 15 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.
