What this shows Akita's Innovation Score is 29.2/100 (30th percentile 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.

Does more volume mean deeper claims for Akita?

Each dot is one of Akita’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Akita’s own 8.6 claims/patent is at or below the 13.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

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.
