What this shows Chenguang's Innovation Score is 53.3/100 (top 9% 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 Chenguang?

Each dot is one of Chenguang’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). Chenguang’s own 14.8 claims/patent is ABOVE the 11.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Chenguang's grants concentrate

Chenguang Biotech Group Co., Ltd. is a focused PatentsView assignee: 20 CPC subclasses with 54.5% of grants classified under A23L (Foods, Foodstuffs OR Non-alcoholic Beverages, NOT Otherwise Provided FOR; Preparation OR Treatment Thereof). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2016. By volume, Chenguang sits between Chainalysis, Inc. and Circassia Limited.

Chenguang's three-year grant acceleration

Chenguang Biotech Group Co., Ltd. shows 8 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.
