What this shows Koei's Innovation Score is 38.5/100 (top 41% 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 Koei?

Each dot is one of Koei’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). Koei’s own 11.8 claims/patent is at or below the 12.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Koei's grants concentrate

Koei Tecmo Games Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 87.5% of grants classified under A63F (Card, Board, OR Roulette GAMES; Indoor Games Using Small Moving Playing BODIES; Video GAMES; Games NOT Otherwise Provided FOR). Peak complete grant year is 2022 (7 grants) versus a trough of 1 in 2017. By volume, Koei sits between John Crane UK Limited and KalVista Pharmaceuticals Limited.

Koei's three-year grant acceleration

Koei Tecmo Games Co., Ltd. shows 9 grants in 2022–2024 against only 7 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.
