What this shows Dupont's Innovation Score is 42.1/100 (top 31% 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 Dupont?

Each dot is one of Dupont’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). Dupont’s own 12.4 claims/patent is at or below the 15.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Dupont's grants concentrate

Dupont Polymers, Inc. is a focused PatentsView assignee: 20 CPC subclasses with 52.4% of grants classified under C08L (Compositions OF Macromolecular Compounds). Peak complete grant year is 2021 (6 grants) versus a trough of 1 in 2019. By volume, Dupont sits between Dieterich Standard, Inc. and Display Technologies, LLC.

Dupont's three-year grant acceleration

Dupont Polymers, Inc. shows 11 grants in 2022–2024 against only 9 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.
