What this shows Sega's Innovation Score is 33.0/100 (43rd percentile 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 Sega?

Each dot is one of Sega’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). Sega’s own 8.9 claims/patent is at or below the 13.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sega's grants concentrate

Sega Corporation is a focused PatentsView assignee: 7 CPC subclasses with 90% 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 2021 (6 grants) versus a trough of 1 in 2015. By volume, Sega sits between Sankyo Seisakusho Co. and Shake-n-go Fashion, Inc..

Sega's three-year grant acceleration

Sega Corporation shows 7 grants in 2022–2024 against only 6 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.
