What this shows POMA's Innovation Score is 44.9/100 (top 24% 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 POMA?

Each dot is one of POMA’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). POMA’s own 14.1 claims/patent is ABOVE the 10.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

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.
