Where Lota's grants concentrate

Lota Xiamen Industry Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 87.5% of grants classified under E03C (Domestic Plumbing Installations FOR Fresh Water OR Waste Water ; Sinks). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2019. By volume, Lota sits between Locatelli S.p.A and Lucida Research LLC.

Lota's three-year grant acceleration

Lota Xiamen Industry Co., Ltd. shows 1 grants in 2022–2024 against only 7 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.
