Does more volume mean deeper claims for Duoject?

Each dot is one of Duoject’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). Duoject’s own 6.9 claims/patent is at or below the 16.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Duoject's grants concentrate

Duoject Medical Systems, Inc. is a focused PatentsView assignee: 6 CPC subclasses with 66.7% of grants classified under A61M (Devices FOR Introducing Media Into, OR Onto, THE Body ; Devices FOR Transducing Body Media OR FOR Taking Media From THE Body ; Devices FOR Producing OR Ending Sleep OR Stupor). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2017. By volume, Duoject sits between Drillmec S.P.A. and Datadog Inc..

Duoject's three-year grant acceleration

Duoject Medical Systems, Inc. shows 3 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.
