What this shows Opro's Innovation Score is 25.8/100 (18th 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 Opro?

Each dot is one of Opro’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). Opro’s own 12.3 claims/patent is at or below the 14.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Opro's grants concentrate

Opro International Limited is a focused PatentsView assignee: 2 CPC subclasses with 66.7% of grants classified under A63B (Apparatus FOR Physical Training, Gymnastics, Swimming, Climbing, OR FENCING; Ball GAMES; Training Equipment). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2019. By volume, Opro sits between Open Innovation Network LLC and Optnics Precision Co., Ltd..

Opro's three-year grant acceleration

Opro International Limited shows 2 grants in 2022–2024 against only 2 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.
