What this shows Curium's Innovation Score is 48.3/100 (top 17% 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 Curium?

Each dot is one of Curium’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). Curium’s own 18.9 claims/patent is ABOVE the 9.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Curium's grants concentrate

Curium US LLC is a focused PatentsView assignee: 32 CPC subclasses with 69.4% of grants classified under G21G (Conversion OF Chemical ELEMENTS; Radioactive Sources). Peak complete grant year is 2020 (8 grants) versus a trough of 3 in 2022. By volume, Curium sits between CircuLite, Inc. and Dedon GmbH.

Curium's three-year grant acceleration

Curium US LLC shows 12 grants in 2022–2024 against only 18 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.
