What this shows Akita's Innovation Score is 42.9/100 (top 29% 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 9.9 claims/patent is at or below the 10.7 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 University is a focused PatentsView assignee: 33 CPC subclasses with 23.5% of grants classified under C08L (Compositions OF Macromolecular Compounds). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2017. By volume, Akita sits between AG Growth International Inc. and Alpinestars Research SRL.

Akita's three-year grant acceleration

Akita University shows 4 grants in 2022–2024 against only 4 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.
