Where Whitefox's grants concentrate

Whitefox Technologies Limited is a focused PatentsView assignee: 9 CPC subclasses with 80% of grants classified under B01D (Separation). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2015. By volume, Whitefox sits between West Virginia University Board of Governors on behalf of West Virginia University and Wintershall Holding GmbH.

Whitefox's three-year grant acceleration

Whitefox Technologies Limited shows 6 grants in 2022–2024 against only 5 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.
