What this shows Delta's Innovation Score is 36.3/100 (top 47% 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.
Delta Scientific Corporation is a focused PatentsView assignee: 6 CPC subclasses with 77.8% of grants classified under E01F (Additional Work, Such AS Equipping Roads OR THE Construction OF Platforms, Helicopter Landing Stages, Signs, Snow Fences, OR THE Like). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2019. By volume, Delta sits between Deckel Maho Seebach GMBH and Deregallera Holdings Ltd.
Delta Scientific Corporation shows 4 grants in 2022–2024 against only 3 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.
