What this shows China's Innovation Score is 30.5/100 (35th percentile 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 China?

Each dot is one of China’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). China’s own 6.1 claims/patent is at or below the 10.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where China's grants concentrate

China National Research Institute OF Food & Fermentation Industries Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 77.8% of grants classified under C07K (Peptides). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2015. By volume, China sits between Chen Sound Industrial Co., Ltd. and Chong Corporation.

China's three-year grant acceleration

China National Research Institute OF Food & Fermentation Industries Co., Ltd. shows 1 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.
