Where Akita's grants concentrate

Akita Prefecture is a focused PatentsView assignee: 10 CPC subclasses with 40% of grants classified under H10N (Electric Solid-state Devices NOT Otherwise Provided FOR). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2021. By volume, Akita sits between Aiviva Biopharma, Inc. and Albea Lacrost.

Akita's three-year grant acceleration

Akita Prefecture 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.
