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 1.9 claims/patent is at or below the 13.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Shanghai's grants concentrate
Shanghai Chuangshi Medical Technology (Group) Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 7.1% 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 2023 (7 grants) versus a trough of 1 in 2024. By volume, Shanghai sits between SeedMaster Manufacturing, Ltd. and Shantou Chenghai District Lele Brothers Toys Co., Ltd.
Shanghai's three-year grant acceleration
Shanghai Chuangshi Medical Technology (Group) Co., Ltd. shows 14 grants in 2022–2024 against only 0 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.
