Does more volume mean deeper claims for Sheng?

Each dot is one of Sheng’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). Sheng’s own 4.5 claims/patent is ABOVE the 2.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Sheng's grants concentrate

Sheng Tai Brassware Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 25% of grants classified under E03C (Domestic Plumbing Installations FOR Fresh Water OR Waste Water ; Sinks). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2020. By volume, Sheng sits between Shantou Weishengda Toys Co., Ltd. and Shenzhen Caross Co., Ltd.

Sheng's three-year grant acceleration

Sheng Tai Brassware Co., Ltd. shows 1 grants in 2022–2024 against only 5 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.
