Does more volume mean deeper claims for Jiangyu?
Each dot is one of Jiangyu’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). Jiangyu’s own 7.9 claims/patent is at or below the 10.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Jiangyu's grants concentrate
Jiangyu Kangjian Innovation Medical Technology (Chengdu) Co., Ltd is a focused PatentsView assignee: 4 CPC subclasses with 30.8% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2023 (8 grants) versus a trough of 2 in 2022. By volume, Jiangyu sits between Jacuzzi Inc. and Just-Evotec Biologics, Inc..
Jiangyu's three-year grant acceleration
Jiangyu Kangjian Innovation Medical Technology (Chengdu) Co., Ltd shows 13 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.
