What this shows Hyosung's Innovation Score is 25.4/100 (17th 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 Hyosung?

Each dot is one of Hyosung’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). Hyosung’s own 9.0 claims/patent is at or below the 11.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
