What this shows Guangxi's Innovation Score is 47.8/100 (top 18% 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 Guangxi?

Each dot is one of Guangxi’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). Guangxi’s own 9.9 claims/patent is ABOVE the 9.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Guangxi's grants concentrate

Guangxi University is a focused PatentsView assignee: 37 CPC subclasses with 31.6% of grants classified under B01J (Chemical OR Physical Processes, e.g. Catalysis OR Colloid CHEMISTRY; Their Relevant Apparatus). Peak complete grant year is 2023 (6 grants) versus a trough of 1 in 2016. By volume, Guangxi sits between Global Circuit Innovations Incorporated and Hangzhou Dptech Technologies Co., Ltd..

Guangxi's three-year grant acceleration

Guangxi University shows 9 grants in 2022–2024 against only 6 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.
