What this shows Yunnan's Innovation Score is 43.1/100 (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 Yunnan?

Each dot is one of Yunnan’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). Yunnan’s own 8.9 claims/patent is at or below the 16.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Yunnan's grants concentrate

Yunnan Academy of Tobacco Agricultural Sciences is a focused PatentsView assignee: 9 CPC subclasses with 71.4% 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 2022 (3 grants) versus a trough of 1 in 2019. By volume, Yunnan sits between Yost Labs Inc. and Zenith Innovation, LLC.

Yunnan's three-year grant acceleration

Yunnan Academy of Tobacco Agricultural Sciences 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.
