What this shows Foshan's Innovation Score is 40.9/100 (top 34% 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 Foshan?

Each dot is one of Foshan’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). Foshan’s own 11.7 claims/patent is ABOVE the 10.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Foshan's grants concentrate

Foshan Carro Electrical Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 80% of grants classified under F04D (Non-positive-displacement Pumps). Peak complete grant year is 2023 (5 grants) versus a trough of 1 in 2019. By volume, Foshan sits between FMC Separation Systems, BV and Freshpoint Quality Assurance Ltd..

Foshan's three-year grant acceleration

Foshan Carro Electrical Co., Ltd. shows 7 grants in 2022–2024 against only 3 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.
