Does more volume mean deeper claims for Hitachi?

Each dot is one of Hitachi’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). Hitachi’s own 27.4 claims/patent is ABOVE the 11.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
