Does more volume mean deeper claims for Imperial?

Each dot is one of Imperial’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). Imperial’s own 15.4 claims/patent is ABOVE the 12.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
