Where Sanexen's grants concentrate

Sanexen Environmental Services Inc. is a focused PatentsView assignee: 17 CPC subclasses with 80% of grants classified under F16L (PIPES; Joints OR Fittings FOR PIPES; Supports FOR Pipes, Cables OR Protective TUBING; Means FOR Thermal Insulation IN General). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2017. By volume, Sanexen sits between Safe Marine Transfer, LLC and Sauter Feinmechanik GMBH.

Sanexen's three-year grant acceleration

Sanexen Environmental Services Inc. shows 2 grants in 2022–2024 against only 5 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.
