What this shows Dunan's Innovation Score is 38.8/100 (top 40% 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 Dunan?

Each dot is one of Dunan’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). Dunan’s own 13.4 claims/patent is at or below the 14.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Dunan's grants concentrate

DunAn Microstaq, Inc. is a focused PatentsView assignee: 25 CPC subclasses with 50% of grants classified under F16K (VALVES; TAPS; COCKS; ACTUATING-FLOATS; Devices FOR Venting OR Aerating). Peak complete grant year is 2020 (9 grants) versus a trough of 1 in 2022. By volume, Dunan sits between Designetics, Inc and Elkem Silicones France SAS.

Dunan's three-year grant acceleration

DunAn Microstaq, Inc. shows 1 grants in 2022–2024 against only 17 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.
