What this shows Hangzhou's Innovation Score is 36.2/100 (top 47% 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 5.9 claims/patent is at or below the 8.1 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 Denghong Technology Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 26.3% of grants classified under G08B (Signalling OR Calling SYSTEMS; Order TELEGRAPHS; Alarm Systems). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2017. By volume, Hangzhou sits between Hu-friedy MFG. Co., LLC and Hayden AI Technologies, Inc..

Hangzhou's three-year grant acceleration

Hangzhou Denghong Technology Co., Ltd. shows 5 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.
