What this shows Jiangmen's Innovation Score is 43.1/100 (top 29% 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 Jiangmen?

Each dot is one of Jiangmen’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). Jiangmen’s own 11.5 claims/patent is ABOVE the 9.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Jiangmen's grants concentrate

Jiangmen City Shengda Lighting Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under F21V (Functional Features OR Details OF Lighting Devices OR Systems THEREOF; Structural Combinations OF Lighting Devices With Other Articles, NOT Otherwise Provided FOR). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2023. By volume, Jiangmen sits between JBS Hair Inc. and Jinyun Reypu Electronic Technology Co., Ltd..

Jiangmen's three-year grant acceleration

Jiangmen City Shengda Lighting Co., Ltd. shows 6 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.
