Where !obac's grants concentrate

!OBAC Limited is a focused PatentsView assignee: 10 CPC subclasses with 100% of grants classified under E04F (Finishing Work ON Buildings, e.g. Stairs, Floors). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2019. By volume, !obac sits between voestalpine Bohler Edelstahl GmbH & Co. KG and 101288550 Saskatchewan Ltd..

!obac's three-year grant acceleration

!OBAC Limited shows 1 grants in 2022–2024 against only 4 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.
