What this shows Noram's Innovation Score is 37.6/100 (top 43% 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 Noram?

Each dot is one of Noram’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). Noram’s own 26.4 claims/patent is ABOVE the 10.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
