What this shows Eigen's Innovation Score is 35.6/100 (top 49% 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 Eigen?

Each dot is one of Eigen’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). Eigen’s own 12.2 claims/patent is at or below the 19.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Eigen's grants concentrate

Eigen Systems Limited is a focused PatentsView assignee: 15 CPC subclasses with 77.8% of grants classified under B23Q (Details, Components, OR Accessories FOR Machine Tools, e.g. Arrangements FOR Copying OR Controlling ; Machine Tools IN General Characterised BY THE Construction OF Particular Details OR COMPONENTS; Co). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2015. By volume, Eigen sits between Economic Alchemy Inc. and EL.EN. S.P.A..

Eigen's three-year grant acceleration

Eigen Systems Limited shows 1 grants in 2022–2024 against only 0 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.
