King LAI Hygienic Materials Co., Ltd is a focused PatentsView assignee: 4 CPC subclasses with 90% of grants classified under F16K (VALVES; TAPS; COCKS; ACTUATING-FLOATS; Devices FOR Venting OR Aerating). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2017. By volume, King sits between Kettering University and KLA-Tencor Technologies Corp..
King LAI Hygienic Materials Co., Ltd shows 4 grants in 2022–2024 against only 1 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.
