Where Clover's grants concentrate

Clover Corporation Limited is a focused PatentsView assignee: 8 CPC subclasses with 25% of grants classified under F16K (VALVES; TAPS; COCKS; ACTUATING-FLOATS; Devices FOR Venting OR Aerating). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2016. By volume, Clover sits between Clearman Labs, LLC and Cobra Fixations Cie Ltée—Cobra Anchors Co. Ltd..

Clover's three-year grant acceleration

Clover Corporation Limited shows 1 grants in 2022–2024 against only 3 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.
