Amethystum Storage Technology Co., Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under G11B (INFORMATION STORAGE BASED ON RELATIVE MOVEMENT BETWEEN RECORD CARRIER AND TRANSDUCER). Peak complete grant year is 2022 (8 grants) versus a trough of 1 in 2017. By volume, Amethystum sits between AMAD Mennekes Holding Gmbh & Co. KG and AMQ Solutions, Llc.
Amethystum Storage Technology Co., Ltd. shows 8 grants in 2022–2024 against only 1 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.
