What this shows Daishinku's Innovation Score is 42.8/100 (top 30% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Where Daishinku's grants concentrate

Daishinku Corporation is a focused PatentsView assignee: 13 CPC subclasses with 88.1% of grants classified under H03H (Impedance Networks, e.g. Resonant CIRCUITS; Resonators). Peak complete grant year is 2015 (9 grants) versus a trough of 3 in 2018. By volume, Daishinku sits between Contitech Transportbandsysteme GmBH and Eva Automation, Inc..

Daishinku's three-year grant acceleration

Daishinku Corporation shows 18 grants in 2022–2024 against only 12 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.
