Where Mast's grants concentrate

Mast Industries (Far East) Limited is a focused PatentsView assignee: 11 CPC subclasses with 68.4% of grants classified under A41C (CORSETS; Brassieres). Peak complete grant year is 2024 (6 grants) versus a trough of 1 in 2018. By volume, Mast sits between Marmon Utility LLC and Metabolic Technologies, LLC.

Mast's three-year grant acceleration

Mast Industries (Far East) Limited shows 7 grants in 2022–2024 against only 6 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.
