What this shows P4's Innovation Score is 29.8/100 (32nd percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for P4?

Each dot is one of P4’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). P4’s own 11.8 claims/patent is at or below the 15.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where P4's grants concentrate

P4 Infrastructure, Inc. is a focused PatentsView assignee: 7 CPC subclasses with 33.3% of grants classified under E01C (Construction OF, OR Surfaces FOR, Roads, Sports Grounds, OR THE LIKE; Machines OR Auxiliary Tools FOR Construction OR Repair). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2021. By volume, P4 sits between Oxyrase, Inc. and Pacific Star Communications.

P4's three-year grant acceleration

P4 Infrastructure, Inc. shows 3 grants in 2022–2024 against only 3 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.
