What this shows Hangzhou's Innovation Score is 37.4/100 (top 44% 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 13.2 claims/patent is ABOVE the 9.9 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 Dptech Technologies Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 84.2% of grants classified under H04L (Transmission OF Digital Information, e.g. Telegraphic Communication). Peak complete grant year is 2019 (5 grants) versus a trough of 1 in 2018. By volume, Hangzhou sits between Guangxi University and Heliatek GMBH.

Hangzhou's three-year grant acceleration

Hangzhou Dptech Technologies Co., Ltd. shows 11 grants in 2022–2024 against only 7 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.
