What this shows Drayson's Innovation Score is 36.5/100 (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 Drayson?

Each dot is one of Drayson’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). Drayson’s own 17.1 claims/patent is ABOVE the 15.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Drayson's grants concentrate

Drayson Technologies (Europe) Limited is a focused PatentsView assignee: 19 CPC subclasses with 68.4% of grants classified under H02J (Circuit Arrangements OR Systems FOR Supplying OR Distributing Electric POWER; Systems FOR Storing Electric Energy). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2024. By volume, Drayson sits between Damon Motors Inc. and Earlysense Ltd..

Drayson's three-year grant acceleration

Drayson Technologies (Europe) Limited shows 1 grants in 2022–2024 against only 12 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.
