What this shows Hangzhou's Innovation Score is 35.8/100 (top 48% 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 16.3 claims/patent is ABOVE the 10.6 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 Weiying Medical Technology Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 57.1% of grants classified under A61F (Filters Implantable Into Blood VESSELS; PROSTHESES; Devices Providing Patency TO, OR Preventing Collapsing OF, Tubular Structures OF THE Body, e.g. STENTS; Orthopaedic, Nursing OR Contraceptive Device). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2022. By volume, Hangzhou sits between Hamlin Electronics (SUZHOU) Ltd. and Happe Spine, LLC.

Hangzhou's three-year grant acceleration

Hangzhou Weiying Medical Technology Co., Ltd. shows 4 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.
