Where ITW's grants concentrate

ITW EF&C Korea LLC. is a focused PatentsView assignee: 6 CPC subclasses with 83.3% of grants classified under B60H (Arrangements OF Heating, Cooling, Ventilating OR Other Air-treating Devices Specially Adapted FOR Passenger OR Goods Spaces OF Vehicles). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2023. By volume, ITW sits between Isringhausen GmbH & Co. KG and Ivtouch Co., Ltd.

ITW's three-year grant acceleration

ITW EF&C Korea LLC. shows 5 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.
