Where Centrotherm's grants concentrate

Centrotherm International AG is a focused PatentsView assignee: 15 CPC subclasses with 33.3% of grants classified under D01F (Chemical Features IN THE Manufacture OF Artificial Filaments, Threads, Fibres, Bristles OR RIBBONS; Apparatus Specially Adapted FOR THE Manufacture OF Carbon Filaments). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2018. By volume, Centrotherm sits between Celmatix, Inc. and Cesign Co., Ltd..

Centrotherm's three-year grant acceleration

Centrotherm International AG shows 3 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.
