Does more volume mean deeper claims for Vale?

Each dot is one of Vale’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). Vale’s own 10.8 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 Vale's grants concentrate

Vale Mill (ROCHDALE) Limited is a focused PatentsView assignee: 4 CPC subclasses with 33.3% of grants classified under A47L (Domestic Washing OR Cleaning ; Suction Cleaners IN General). Peak complete grant year is 2018 (2 grants) versus a trough of 1 in 2016. By volume, Vale sits between V-Silicon Semiconductor (Hefei) Co., Ltd and Vamco International, Inc..

Vale's three-year grant acceleration

Vale Mill (ROCHDALE) Limited shows 2 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.
