What this shows ALD's Innovation Score is 43.4/100 (top 28% 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 ALD?

Each dot is one of ALD’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). ALD’s own 5.2 claims/patent is at or below the 9.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where ALD's grants concentrate

ALD Group Limited is a focused PatentsView assignee: 10 CPC subclasses with 23.1% of grants classified under H05B (Electric HEATING; Electric Light Sources NOT Otherwise Provided FOR; Circuit Arrangements FOR Electric Light Sources, IN General). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2021. By volume, ALD sits between Aisin Kako Kabushiki Kaisha and Almus Corp..

ALD's three-year grant acceleration

ALD Group Limited shows 8 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.
