What this shows Guangxi's Innovation Score is 35.7/100 (top 48% 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 11.6 claims/patent is at or below the 17.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Guangxi's grants concentrate

Guangxi Liugong Machinery Co., Ltd. is a focused PatentsView assignee: 18 CPC subclasses with 56% of grants classified under E02F (DREDGING; Soil-shifting). Peak complete grant year is 2020 (11 grants) versus a trough of 1 in 2017. By volume, Guangxi sits between Global Nuclear Fuel-Americas, LLC and Helmut Fischer GMBH Institut FÜR Elektronik UND Messtechnik.

Guangxi's three-year grant acceleration

Guangxi Liugong Machinery Co., Ltd. shows 6 grants in 2022–2024 against only 16 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.
