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.

Does more volume mean deeper claims for Delta?

Each dot is one of Delta’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). Delta’s own 18.0 claims/patent is ABOVE the 11.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Delta's grants concentrate

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's three-year grant acceleration

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.
