Does more volume mean deeper claims for Chinook?

Each dot is one of Chinook’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). Chinook’s own 25.6 claims/patent is ABOVE the 15.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Chinook's grants concentrate

Chinook Therapeutics, Inc. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2022. By volume, Chinook sits between Chen Tian Co., Ltd. and Cisco Systems Inc..

Chinook's three-year grant acceleration

Chinook Therapeutics, Inc. shows 3 grants in 2022–2024 against only 4 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.
