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 7.1 claims/patent is at or below the 10.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Shanghai's grants concentrate
Shanghai Tosun Technology Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 75% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2023. By volume, Shanghai sits between Shanghai Sany Heavy Machinery Co., Ltd and Share Edge, LLC.
Shanghai's three-year grant acceleration
Shanghai Tosun Technology Ltd. shows 3 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.
