Where Maillefer's grants concentrate

Maillefer S.A. is a focused PatentsView assignee: 20 CPC subclasses with 50% of grants classified under B29C (Shaping OR Joining OF PLASTICS; Shaping OF Material IN A Plastic State, NOT Otherwise Provided FOR; After-treatment OF THE Shaped Products, e.g. Repairing). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2015. By volume, Maillefer sits between Magnum Venus Products, Inc. and Mannoh Industrial Co., Ltd..

Maillefer's three-year grant acceleration

Maillefer S.A. shows 1 grants in 2022–2024 against only 0 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.
