What this shows Dupont's Innovation Score is 55.9/100 (top 6% 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 14.0 claims/patent is at or below the 17.4 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 Toray Specialty Materials Kabushiki Kaisha is a focused PatentsView assignee: 22 CPC subclasses with 69.6% of grants classified under C08L (Compositions OF Macromolecular Compounds). Peak complete grant year is 2023 (7 grants) versus a trough of 4 in 2021. By volume, Dupont sits between Dispensing Technologies B.V. and Eygs LLP.

Dupont's three-year grant acceleration

DuPont Toray Specialty Materials Kabushiki Kaisha shows 15 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.
