Where Amkor's grants concentrate

Amkor Technology Japan, Inc. is a focused PatentsView assignee: 2 CPC subclasses with 100% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). By volume, Amkor sits between American Water Works Company, Inc. and Analytik Jena GmbH+Co. KG.

Amkor's three-year grant acceleration

Amkor Technology Japan, Inc. shows 6 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.
