Where Daikyonishikawa's grants concentrate

Daikyonishikawa Corporation is a focused PatentsView assignee: 18 CPC subclasses with 30% of grants classified under B01D (SEPARATION). Peak complete grant year is 2015 (5 grants) versus a trough of 1 in 2018. By volume, Daikyonishikawa sits between Dwolla, Inc. and Danapak Flexibles A/s.

Daikyonishikawa's three-year grant acceleration

Daikyonishikawa Corporation shows 2 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.
