Where Lystek's grants concentrate

Lystek International Corp. is a focused PatentsView assignee: 8 CPC subclasses with 83.3% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2015. By volume, Lystek sits between Lunghwa University of Science and Technology and Macstadium, Inc..

Lystek's three-year grant acceleration

Lystek International Corp. shows 2 grants in 2022–2024 against only 1 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.
