Prinoth S.P.A. is a focused PatentsView assignee: 23 CPC subclasses with 64.7% of grants classified under E01H (Street CLEANING; Cleaning OF Permanent WAYS; Cleaning BEACHES; Dispersing ; OR PREVENTING; FOG IN General ; Cleaning Street OR Railway Furniture OR Tunnel Walls). Peak complete grant year is 2023 (6 grants) versus a trough of 3 in 2019. By volume, Prinoth sits between Oldcastle Precast Inc. and Pentair Residential Filtration, LLC.
Prinoth S.P.A. shows 13 grants in 2022–2024 against only 11 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.
