Does more volume mean deeper claims for Amethystum?
Each dot is one of Amethystum’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Amethystum’s own 15.7 claims/patent is ABOVE the 6.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Amethystum's grants concentrate
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's three-year grant acceleration
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.
