What this shows Foshan's Innovation Score is 47.2/100 (top 19% 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 15.2 claims/patent is ABOVE the 13.5 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 Nationstar Optoelectronics Co., Ltd. is a focused PatentsView assignee: 19 CPC subclasses with 71.4% of grants classified under H10H (Inorganic Light-emitting Semiconductor Devices Having Potential Barriers). Peak complete grant year is 2024 (11 grants) versus a trough of 1 in 2015. By volume, Foshan sits between Expectations, LLC and Gainspan Corporation.

Foshan's three-year grant acceleration

Foshan Nationstar Optoelectronics Co., Ltd. shows 20 grants in 2022–2024 against only 13 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.
