Where Sasol's grants concentrate

Sasol Technology Proprietary Limited is a focused PatentsView assignee: 22 CPC subclasses with 63.4% of grants classified under C10G (Cracking Hydrocarbon OILS; Production OF Liquid Hydrocarbon Mixtures, e.g. BY Destructive Hydrogenation, Oligomerisation, Polymerisation ; Recovery OF Hydrocarbon Oils From Oil-shale, Oil-sand, OR GAS). Peak complete grant year is 2016 (12 grants) versus a trough of 1 in 2022. By volume, Sasol sits between Reel Power Licensing Corp. and Shya Hsin Packaging Industry (CHINA) Co., Ltd..

Sasol's three-year grant acceleration

Sasol Technology Proprietary Limited shows 1 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.
