Portfolio overview
L.B. Foster Rail Technologies, Inc. has been granted 13 US utility patents between 2015 and 2024, placing L.B. Foster Rail Technologies, Inc. at rank #21,359 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.9 claims per patent with primary concentration in B61K (AUXILIARY EQUIPMENT SPECIALLY ADAPTED FOR RAILWAYS, NOT OTHERWISE PROVIDED FOR). As a US Corporation, L.B. Foster Rail Technologies, Inc. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 34.7/100 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 4 grants, compared with 9 in the 2015–2019 window — a -56% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US 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. L.B. Foster Rail Technologies, Inc.'s 14.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 8 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark L.B. Foster Rail Technologies, Inc. against peers pursuing similar technology classes.
