Where Duratap's grants concentrate

Duratap LLC is a focused PatentsView assignee: 1 CPC subclasses with 22.2% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2018 (7 grants) versus a trough of 1 in 2019. By volume, Duratap sits between Drymax Technologies, Inc. and Dynasol ELASTÓMEROS, S.A.U..

Duratap's three-year grant acceleration

Duratap LLC shows 1 grants in 2022–2024 against only 1 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.
