Portfolio overview
POMA has been granted 23 US utility patents between 2017 and 2025, placing POMA at rank #13,100 across all assignees tracked by PlainPatent. This portfolio spans 18 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.1 claims per patent with primary concentration in B61B (RAILWAY SYSTEMS; EQUIPMENT THEREFOR NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, POMA is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 44.9/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.
Filing cadence tells the strategic story. Between 2020 and 2025 the company received 20 grants, compared with 3 in the 2015–2019 window — a +567% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.
Claim depth and technology breadth together indicate competitive posture. POMA's 14.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 18 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark POMA against peers pursuing similar technology classes.
