Where Chart's grants concentrate

Chart Energy & Chemicals, Inc. is a focused PatentsView assignee: 8 CPC subclasses with 96.2% of grants classified under F25J (Liquefaction, Solidification OR Separation OF Gases OR Gaseous ; OR Liquefied GASEOUS; Mixtures BY Pressure AND Cold Treatment ; OR BY Bringing Them Into THE Supercritical State). Peak complete grant year is 2023 (6 grants) versus a trough of 1 in 2018. By volume, Chart sits between Centre Firearms Co., Inc. and Chromatic Technologies, Inc..

Chart's three-year grant acceleration

Chart Energy & Chemicals, Inc. shows 13 grants in 2022–2024 against only 8 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.
