Where Isotopx's grants concentrate

Isotopx Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under H01J (Electric Discharge Tubes OR Discharge Lamps). Peak complete grant year is 2022 (3 grants) versus a trough of 2 in 2023. By volume, Isotopx sits between Iron Gaming Limited and ITP Next Generation Turbines S.L..

Isotopx's three-year grant acceleration

Isotopx Ltd. shows 5 grants in 2022–2024 against only 0 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.
