What this shows CHA's Innovation Score is 46.3/100 (top 21% 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 CHA?

Each dot is one of CHA’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). CHA’s own 5.4 claims/patent is at or below the 12.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where CHA's grants concentrate

CHA University Industry-academic Cooperation Foundation is a focused PatentsView assignee: 16 CPC subclasses with 33.3% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2024 (3 grants) versus a trough of 2 in 2022. By volume, CHA sits between Cellectis SA and China Electronics Technology Group Corporation NO 44 Research Institute.

CHA's three-year grant acceleration

CHA University Industry-academic Cooperation Foundation shows 7 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.
