What this shows Adey's Innovation Score is 45.6/100 (top 23% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Adey?

Each dot is one of Adey’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). Adey’s own 8.4 claims/patent is at or below the 14.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Adey's grants concentrate

Adey Holdings (2008) Limited is a focused PatentsView assignee: 17 CPC subclasses with 46.3% of grants classified under B03C (Magnetic OR Electrostatic Separation OF Solid Materials From Solid Materials OR FLUIDS; Separation BY High-voltage Electric Fields). Peak complete grant year is 2022 (16 grants) versus a trough of 1 in 2016. By volume, Adey sits between i4F Licensing NV and Areva NP.

Adey's three-year grant acceleration

Adey Holdings (2008) Limited shows 24 grants in 2022–2024 against only 14 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.
