What this shows Statoil's Innovation Score is 27.9/100 (25th 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 Statoil?

Each dot is one of Statoil’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). Statoil’s own 14.0 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.
