Does more volume mean deeper claims for Amkor?

Each dot is one of Amkor’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). Amkor’s own 19.0 claims/patent is ABOVE the 15.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
