Where Fontaine's grants concentrate

Fontaine Holdings Nv is a focused PatentsView assignee: 13 CPC subclasses with 100% of grants classified under C23C (COATING METALLIC MATERIAL; COATING MATERIAL WITH METALLIC MATERIAL; SURFACE TREATMENT OF METALLIC MATERIAL BY DIFFUSION INTO THE SURFACE, BY CHEMICAL CONVERSION OR SUBSTITUTION; COATING BY VACUUM EVAP). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2019. By volume, Fontaine sits between Flomatic Corporation and Founder Apabi Technology Limited.

Fontaine's three-year grant acceleration

Fontaine Holdings Nv shows 4 grants in 2022–2024 against only 6 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.
