Does more volume mean deeper claims for Kangpu?

Each dot is one of Kangpu’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). Kangpu’s own 16.5 claims/patent is ABOVE the 11.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Kangpu's grants concentrate

Kangpu Biopharmaceuticals, Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2018. By volume, Kangpu sits between KaliVir Immunotherapeutcs, Inc. and Karltex Machine, Inc..

Kangpu's three-year grant acceleration

Kangpu Biopharmaceuticals, Ltd. shows 3 grants in 2022–2024 against only 2 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.
