What this shows Shanghai's Innovation Score is 35.5/100 (top 49% 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 Shanghai?

Each dot is one of Shanghai’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). Shanghai’s own 14.2 claims/patent is ABOVE the 11.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Shanghai's grants concentrate

Shanghai Microport Cardioflow Medtech Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 89.5% 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 2018 (4 grants) versus a trough of 1 in 2019. By volume, Shanghai sits between Sentec Ltd and Shenzhen Gloshine Technology Co., Ltd..

Shanghai's three-year grant acceleration

Shanghai Microport Cardioflow Medtech Co., Ltd. shows 6 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.
