Where ipek's grants concentrate

iPEK International GmbH is a focused PatentsView assignee: 24 CPC subclasses with 73.3% of grants classified under E03F (SEWERS; Cesspools). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2019. By volume, ipek sits between Zhuhai Shengchang Electronics Co., Ltd. and 1ahead Technologies.

ipek's three-year grant acceleration

iPEK International GmbH shows 4 grants in 2022–2024 against only 5 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.
