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.

Does more volume mean deeper claims for P.v.?

Each dot is one of P.v.’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). P.v.’s own 16.9 claims/patent is ABOVE the 10.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

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.
