Does more volume mean deeper claims for Shanghai?

Each dot is one of Shanghai’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). Shanghai’s own 20.0 claims/patent is ABOVE the 10.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Shanghai's grants concentrate

Shanghai Linghuo Trading Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 90% of grants classified under B60B (Vehicle Wheels ; CASTORS; Axles FOR Wheels OR CASTORS; Increasing Wheel Adhesion). Peak complete grant year is 2024 (6 grants) versus a trough of 4 in 2023. By volume, Shanghai sits between SFC Global Supply Chain, Inc. and Shen Zhen Stand BY ME Technology Limited.

Shanghai's three-year grant acceleration

Shanghai Linghuo Trading Co., Ltd. shows 10 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.
