Does more volume mean deeper claims for Kingdream?

Each dot is one of Kingdream’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). Kingdream’s own 13.2 claims/patent is at or below the 14.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kingdream's grants concentrate

Kingdream Public Limited Company is a focused PatentsView assignee: 3 CPC subclasses with 83.3% of grants classified under E21B (Earth OR Rock DRILLING; Obtaining OIL, GAS, Water, Soluble OR Meltable Materials OR A Slurry OF Minerals From Wells).

Kingdream's three-year grant acceleration

Kingdream Public Limited Company shows 3 grants in 2022–2024 against only 0 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
