What this shows Dunlop's Innovation Score is 49.9/100 (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 Dunlop?

Each dot is one of Dunlop’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). Dunlop’s own 10.1 claims/patent is at or below the 18.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Dunlop's grants concentrate

Dunlop Sports Co., Ltd. is a focused PatentsView assignee: 39 CPC subclasses with 70.5% of grants classified under A63B (Apparatus FOR Physical Training, Gymnastics, Swimming, Climbing, OR FENCING; Ball GAMES; Training Equipment). Peak complete grant year is 2017 (125 grants) versus a trough of 1 in 2021. By volume, Dunlop sits between Magna Mirrors of America, Inc. and Gracenote, Inc..

Dunlop's three-year grant acceleration

Dunlop Sports Co., Ltd. shows 2 grants in 2022–2024 against only 16 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.
