Does more volume mean deeper claims for Clover?
Each dot is one of Clover’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Clover’s own 3.1 claims/patent is at or below the 12.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
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.
