What this shows Kyoto's Innovation Score is 46.4/100 (top 21% 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 Kyoto?

Each dot is one of Kyoto’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). Kyoto’s own 9.6 claims/patent is at or below the 15.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kyoto's grants concentrate

Kyoto Prefectural Public University Corporation is a focused PatentsView assignee: 19 CPC subclasses with 58.3% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2023 (11 grants) versus a trough of 1 in 2018. By volume, Kyoto sits between J.A. Woollam Co., Inc. and Lightel Technologies, Inc..

Kyoto's three-year grant acceleration

Kyoto Prefectural Public University Corporation shows 23 grants in 2022–2024 against only 13 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.
