Where Nanjing's grants concentrate
Nanjing Huandatong Electronic Technology Co., Ltd is a focused PatentsView assignee: 1 CPC subclasses with 20% of grants classified under A47C (CHAIRS; SOFAS; Beds). By volume, Nanjing sits between Nvmdurance Limited and Nano Pharmaceutical Laboratories LLC.
Nanjing's three-year grant acceleration
Nanjing Huandatong Electronic Technology Co., Ltd shows 2 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.
