What this shows Graphenea's Innovation Score is 28.9/100 (29th 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 Graphenea?

Each dot is one of Graphenea’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). Graphenea’s own 8.4 claims/patent is at or below the 18.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Graphenea's grants concentrate

Graphenea S.A. is a focused PatentsView assignee: 18 CPC subclasses with 85.7% of grants classified under C01B (Non-metallic ELEMENTS; Compounds THEREOF; ; Metalloids OR Compounds Thereof NOT Covered BY Subclass C01c). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2015. By volume, Graphenea sits between GOTOHTI.COM Inc. and Green Wave Power Systems LLC.

Graphenea's three-year grant acceleration

Graphenea S.A. shows 1 grants in 2022–2024 against only 4 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.
