Where Plusprings's grants concentrate
Plusprings Machinery Co., Ltd is a focused PatentsView assignee: 1 CPC subclasses with 100% of grants classified under B21F (Working OR Processing OF Metal Wire). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2021. By volume, Plusprings sits between PLS Technologies, Inc. and Podtrac, Inc..
Plusprings's three-year grant acceleration
Plusprings Machinery Co., Ltd shows 1 grants in 2022–2024 against only 1 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.
