Where POMA's grants concentrate

POMA is a focused PatentsView assignee: 18 CPC subclasses with 82.6% of grants classified under B61B (Railway SYSTEMS; Equipment Therefor NOT Otherwise Provided FOR). Peak complete grant year is 2023 (7 grants) versus a trough of 1 in 2017. By volume, POMA sits between PCP Tactical, LLC and Public University Corporation Nagoya City University.

POMA's three-year grant acceleration

POMA shows 11 grants in 2022–2024 against only 7 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.
