What this shows ARK's Innovation Score is 29.2/100 (30th 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 ARK?

Each dot is one of ARK’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). ARK’s own 11.8 claims/patent is at or below the 13.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where ARK's grants concentrate

ARK Crystal, LLC is a focused PatentsView assignee: 10 CPC subclasses with 40% of grants classified under C30B (Single-crystal Growth ; Unidirectional Solidification OF Eutectic Material OR Unidirectional Demixing OF Eutectoid MATERIAL; Refining BY Zone-melting OF Material ; Production OF A Homogeneous Polycrys). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2018. By volume, ARK sits between Areva Stockage d'Energie and AS Strömungstechnik GmbH.

ARK's three-year grant acceleration

ARK Crystal, LLC 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.
