Does more volume mean deeper claims for Chart?
Each dot is one of Chart’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Chart’s own 18.3 claims/patent is ABOVE the 13.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
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.
