What this shows Chinese's Innovation Score is 35.5/100 (top 49% 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 Chinese?

Each dot is one of Chinese’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). Chinese’s own 7.0 claims/patent is at or below the 12.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Chinese's grants concentrate

Chinese Academy of Sciences (CAS) is a focused PatentsView assignee: 11 CPC subclasses with 20% of grants classified under C12N (Microorganisms OR ENZYMES; Compositions THEREOF; Propagating, Preserving, OR Maintaining MICROORGANISMS; Mutation OR Genetic ENGINEERING; Culture Media). By volume, Chinese sits between Children's Research Institute, Children's National Medical Center and Chiscan Holdings PTE. Ltd.

Chinese's three-year grant acceleration

Chinese Academy of Sciences (CAS) shows 2 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.
