What this shows Kinki's Innovation Score is 49.6/100 (top 14% 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 Kinki?

Each dot is one of Kinki’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). Kinki’s own 11.3 claims/patent is at or below the 14.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kinki's grants concentrate

Kinki University is a focused PatentsView assignee: 41 CPC subclasses with 54.8% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2020 (6 grants) versus a trough of 1 in 2016. By volume, Kinki sits between Joyson Safety Systems Germany GmbH and Kindred Systems Inc..

Kinki's three-year grant acceleration

Kinki University shows 11 grants in 2022–2024 against only 9 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.
