Where Pliant's grants concentrate

Pliant Energy Systems Inc. is a focused PatentsView assignee: 18 CPC subclasses with 80% of grants classified under F03B (Machines OR Engines FOR Liquids). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2015. By volume, Pliant sits between Plasan Sasa Ltd. and Posco LED Company Ltd..

Pliant's three-year grant acceleration

Pliant Energy Systems Inc. shows 2 grants in 2022–2024 against only 4 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.
