Does more volume mean deeper claims for Enerkem?

Each dot is one of Enerkem’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). Enerkem’s own 21.4 claims/patent is ABOVE the 15.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
