Where Taizhou's grants concentrate

Taizhou Dajiang IND. Co. Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 80% of grants classified under B25C (Hand-held Nailing OR Stapling TOOLS; Manually Operated Portable Stapling Tools). Peak complete grant year is 2017 (8 grants) versus a trough of 1 in 2022. By volume, Taizhou sits between Systems Spray-Cooled, Inc. and Technova Inc..

Taizhou's three-year grant acceleration

Taizhou Dajiang IND. Co. Ltd. shows 3 grants in 2022–2024 against only 2 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.
