Where Prismlab's grants concentrate

Prismlab China Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 100% of grants classified under B33Y (Additive Manufacturing, i.e. Manufacturing OF Three-dimensional [3-D] Objects BY Additive Deposition, Additive Agglomeration OR Additive Layering, e.g. BY 3-D Printing, Stereolithography OR Selective ). By volume, Prismlab sits between Prism Fitness, Inc. and Procarta Biosystems Ltd..

Prismlab's three-year grant acceleration

Prismlab China Ltd. shows 2 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.
