Where Ludwig's grants concentrate

Ludwig Hettich Holding GmbH & Co. KG is a focused PatentsView assignee: 11 CPC subclasses with 100% of grants classified under F16B (Devices FOR Fastening OR Securing Constructional Elements OR Machine Parts Together, e.g. Nails, Bolts, Circlips, Clamps, Clips OR WEDGES; Joints OR Jointing).

Ludwig's three-year grant acceleration

Ludwig Hettich Holding GmbH & Co. KG shows 4 grants in 2022–2024 against only 2 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.
