What this shows Dromont's Innovation Score is 47.1/100 (top 19% 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 Dromont?

Each dot is one of Dromont’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). Dromont’s own 6.3 claims/patent is at or below the 16.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Dromont's grants concentrate

Dromont S.p.A. is a focused PatentsView assignee: 18 CPC subclasses with 60% of grants classified under B01F (Mixing, e.g. Dissolving, Emulsifying OR Dispersing). Peak complete grant year is 2023 (6 grants) versus a trough of 1 in 2024. By volume, Dromont sits between Dosan Enerbility Co., Ltd. and Drug Plastics & Glass Company, Inc..

Dromont's three-year grant acceleration

Dromont S.p.A. shows 10 grants in 2022–2024 against only 0 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.
