What this shows Wheelabrator's Innovation Score is 31.3/100 (37th percentile 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 Wheelabrator?

Each dot is one of Wheelabrator’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). Wheelabrator’s own 14.4 claims/patent is ABOVE the 12.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Wheelabrator's grants concentrate

Wheelabrator Group Limited is a focused PatentsView assignee: 12 CPC subclasses with 92.3% of grants classified under B24C (Abrasive OR Related Blasting With Particulate Material). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2015. By volume, Wheelabrator sits between Wearable Technology Limited and Winstron Corporation.

Wheelabrator's three-year grant acceleration

Wheelabrator Group Limited shows 1 grants in 2022–2024 against only 5 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.
