What this shows 3nine's Innovation Score is 23.4/100 (12th 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 3nine?

Each dot is one of 3nine’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). 3nine’s own 12.0 claims/patent is at or below the 14.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
