What this shows CHA's Innovation Score is 43.2/100 (top 29% 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 11.1 claims/patent is at or below the 12.9 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 Biotech Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 100% of grants classified under C12N (Microorganisms OR ENZYMES; Compositions THEREOF; Propagating, Preserving, OR Maintaining MICROORGANISMS; Mutation OR Genetic ENGINEERING; Culture Media). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2019. By volume, CHA sits between Certainteed Gypsum AND Ceiling Manufacturing Inc. and Chase Therapeutics Corporation.

CHA's three-year grant acceleration

CHA Biotech Co., Ltd. shows 4 grants in 2022–2024 against only 1 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.
