Does more volume mean deeper claims for Corning?

Each dot is one of Corning’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). Corning’s own 19.7 claims/patent is ABOVE the 15.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
