Where Vulcan's grants concentrate

Vulcan Technologies Shanghai Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 77.8% of grants classified under H04L (Transmission OF Digital Information, e.g. Telegraphic Communication). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2020. By volume, Vulcan sits between Vortech Engineering, Inc. and Ways Technical Corp., Ltd..

Vulcan's three-year grant acceleration

Vulcan Technologies Shanghai Co., Ltd. shows 5 grants in 2022–2024 against only 4 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.
