What this shows Hangzhou's Innovation Score is 30.4/100 (34th percentile 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 17.2 claims/patent is ABOVE the 10.0 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 Yameilijia Technology Co., Ltd is a focused PatentsView assignee: 12 CPC subclasses with 80% of grants classified under B25J (MANIPULATORS; Chambers Provided With Manipulation Devices). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2022. By volume, Hangzhou sits between Handle Financial, Inc. and Hansa Medical AB.

Hangzhou's three-year grant acceleration

Hangzhou Yameilijia Technology Co., Ltd shows 1 grants in 2022–2024 against only 4 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.
