What this shows Rolls-royce's Innovation Score is 36.6/100 (top 46% 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 Rolls-royce?

Each dot is one of Rolls-royce’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). Rolls-royce’s own 15.2 claims/patent is ABOVE the 12.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Rolls-royce's grants concentrate

Rolls-royce Power Engineering PLC is a focused PatentsView assignee: 21 CPC subclasses with 45.5% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2015. By volume, Rolls-royce sits between Robopac S.P.A. and Rassini Suspensiones, S.A. de C.V..

Rolls-royce's three-year grant acceleration

Rolls-royce Power Engineering PLC shows 2 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.
