Does more volume mean deeper claims for Marshalltown?

Each dot is one of Marshalltown’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). Marshalltown’s own 4.3 claims/patent is at or below the 16.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Marshalltown's grants concentrate

Marshalltown Company is a focused PatentsView assignee: 5 CPC subclasses with 10.5% of grants classified under E01C (Construction OF, OR Surfaces FOR, Roads, Sports Grounds, OR THE LIKE; Machines OR Auxiliary Tools FOR Construction OR Repair).

Marshalltown's three-year grant acceleration

Marshalltown Company shows 10 grants in 2022–2024 against only 5 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.
