What this shows DE's Innovation Score is 29.3/100 (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 DE?

Each dot is one of DE’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). DE’s own 11.8 claims/patent is at or below the 20.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where DE's grants concentrate

DE Nora Holdings US, Inc. is a focused PatentsView assignee: 7 CPC subclasses with 80% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). By volume, DE sits between DCB Solutions Limited and Debregeas ET Associes Pharma.

DE's three-year grant acceleration

DE Nora Holdings US, Inc. shows 2 grants in 2022–2024 against only 2 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.
