Where CEJN's grants concentrate

CEJN AB is a focused PatentsView assignee: 11 CPC subclasses with 90.9% 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 2017 (2 grants) versus a trough of 1 in 2016. By volume, CEJN sits between Cardiologs Technologies SAS and CHAD Dorsey Design, Llc.

CEJN's three-year grant acceleration

CEJN AB shows 2 grants in 2022–2024 against only 4 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.
