What this shows Foshan's Innovation Score is 20.7/100 (7th 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 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 2.8 claims/patent is at or below the 12.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Foshan's grants concentrate

Foshan Electrical AND Lighting Co., Ltd is a focused PatentsView assignee: 3 CPC subclasses with 20% of grants classified under H05B (Electric HEATING; Electric Light Sources NOT Otherwise Provided FOR; Circuit Arrangements FOR Electric Light Sources, IN General). Peak complete grant year is 2018 (4 grants) versus a trough of 1 in 2022. By volume, Foshan sits between Fortior Technology (SHENZHEN) Co., Ltd. and Fouring Co., Ltd.

Foshan's three-year grant acceleration

Foshan Electrical AND Lighting Co., Ltd shows 1 grants in 2022–2024 against only 0 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.
