What this shows P.v.'s Innovation Score is 34.7/100 (48th 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.

Where P.v.'s grants concentrate

P.V. Flood Control Corp. is a focused PatentsView assignee: 4 CPC subclasses with 61.5% of grants classified under E02B (Hydraulic Engineering). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2015. By volume, P.v. sits between Ortho Solutions, LC and Park WAY Co., Ltd..

P.v.'s three-year grant acceleration

P.V. Flood Control Corp. shows 5 grants in 2022–2024 against only 4 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.
