What this shows Semes's Innovation Score is 71.7/100 (top 1% 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 Semes?

Each dot is one of Semes’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). Semes’s own 14.4 claims/patent is ABOVE the 13.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
