Does more volume mean deeper claims for Quanzhou?

Each dot is one of Quanzhou’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). Quanzhou’s own 20.6 claims/patent is ABOVE the 15.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Quanzhou's grants concentrate

Quanzhou Sanan Semiconductor Technology Co., Ltd is a focused PatentsView assignee: 5 CPC subclasses with 93.9% of grants classified under H10H (Inorganic Light-emitting Semiconductor Devices Having Potential Barriers). Peak complete grant year is 2024 (16 grants) versus a trough of 1 in 2023. By volume, Quanzhou sits between Portal Instruments, Inc. and Redbox Automated Retail, LLC.

Quanzhou's three-year grant acceleration

Quanzhou Sanan Semiconductor Technology Co., Ltd shows 19 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.
