Where Paul's grants concentrate

Paul Wurth Deutschland GMBH is a focused PatentsView assignee: 7 CPC subclasses with 80% of grants classified under F27D (Details OR Accessories OF Furnaces, Kilns, Ovens OR Retorts, IN SO FAR AS They ARE OF Kinds Occurring IN More Than ONE Kind OF Furnace). By volume, Paul sits between Patron Spirits International AG and Pccw Vuclip (Singapore) Pte. Ltd..

Paul's three-year grant acceleration

Paul Wurth Deutschland GMBH shows 2 grants in 2022–2024 against only 1 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.
