Where Toshiba's grants concentrate

Toshiba Carrier Corporation is a focused PatentsView assignee: 26 CPC subclasses with 37.5% of grants classified under F25B (Refrigeration Machines, Plants OR SYSTEMS; Combined Heating AND Refrigeration SYSTEMS; Heat Pump Systems). Peak complete grant year is 2018 (8 grants) versus a trough of 2 in 2016. By volume, Toshiba sits between Silgan Containers LLC and Ugreen Group Limited.

Toshiba's three-year grant acceleration

Toshiba Carrier Corporation shows 20 grants in 2022–2024 against only 11 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.
