What this shows Kurume's Innovation Score is 36.7/100 (top 46% 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 Kurume?

Each dot is one of Kurume’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). Kurume’s own 8.1 claims/patent is ABOVE the 8.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Kurume's grants concentrate

Kurume University is a focused PatentsView assignee: 25 CPC subclasses with 38.9% of grants classified under C12N (Microorganisms OR ENZYMES; Compositions THEREOF; Propagating, Preserving, OR Maintaining MICROORGANISMS; Mutation OR Genetic ENGINEERING; Culture Media). Peak complete grant year is 2016 (4 grants) versus a trough of 1 in 2017. By volume, Kurume sits between Kinova Inc. and Knog Pty Ltd.

Kurume's three-year grant acceleration

Kurume University shows 3 grants in 2022–2024 against only 5 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.
