Where Hefei's grants concentrate

Hefei Tuwa Technology Co., Ltd. is a focused PatentsView assignee: 0 CPC subclasses . Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2024. By volume, Hefei sits between Hearth Products Controls Co. and Helion Biotech ApS.

Hefei's three-year grant acceleration

Hefei Tuwa Technology Co., Ltd. shows 1 grants in 2022–2024 against only 2 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.
