Hangzhou LHD Institute OF NEW Energy, LLC is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under F03B (Machines OR Engines FOR Liquids). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2015. By volume, Hangzhou sits between Hangzhou Canaan Intelligence Information Technology Co., Ltd and Hangzhou Sicco Art-technology Co., Ltd.
Hangzhou LHD Institute OF NEW Energy, LLC shows 3 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.
