What this shows Elliott's Innovation Score is 53.1/100 (top 9% 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 Elliott?

Each dot is one of Elliott’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). Elliott’s own 15.4 claims/patent is ABOVE the 14.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Elliott's grants concentrate

Elliott Group Limited is a focused PatentsView assignee: 15 CPC subclasses with 44.4% of grants classified under F05D (Indexing Scheme FOR Aspects Relating TO Non-positive-displacement Machines OR Engines, Gas-turbines OR Jet-propulsion Plants). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2016. By volume, Elliott sits between Ebner Industrieofenbau GmbH and Enensys Technologies.

Elliott's three-year grant acceleration

Elliott Group Limited shows 9 grants in 2022–2024 against only 2 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.
