Where Sani-tech's grants concentrate

Sani-tech West, Inc. is a focused PatentsView assignee: 11 CPC subclasses with 57.1% of grants classified under C12M (Apparatus FOR Enzymology OR MICROBIOLOGY; Apparatus FOR Culturing Microorganisms FOR Producing Biomass, FOR Growing Cells OR FOR Obtaining Fermentation OR Metabolic Products, i.e. Bioreactors OR Ferme). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2021. By volume, Sani-tech sits between Samwon ACT Co., Ltd. and Saol International Limited.

Sani-tech's three-year grant acceleration

Sani-tech West, Inc. shows 1 grants in 2022–2024 against only 6 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.
