What this shows Ajinomoto's Innovation Score is 57.3/100 (top 5% 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 Ajinomoto?

Each dot is one of Ajinomoto’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). Ajinomoto’s own 14.4 claims/patent is at or below the 14.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
