Where Quantalrf's grants concentrate

Quantalrf AG is a focused PatentsView assignee: 5 CPC subclasses with 80% of grants classified under H03F (Amplifiers). Peak complete grant year is 2024 (5 grants) versus a trough of 3 in 2019. By volume, Quantalrf sits between Qinghai Institute OF Salt Lakes, Chinese Academy OF Sciences and Quixant PLC.

Quantalrf's three-year grant acceleration

Quantalrf AG shows 5 grants in 2022–2024 against only 3 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.
