USPTO PatentsView assignee record - 18 granted patents across 13 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: E01B (PERMANENT WAY; PERMANENT-WAY TOOLS; MACHINES FOR MAKING RAILWAYS OF ALL KINDS).
The verdict
Herzog holds 18 US patents across 13 technology areas, rank #16,086 of 50,000 tracked assignees.
Herzog Railroad Services, Inc. has been granted 18 US utility patents between 2015 and 2025, placing Herzog Railroad Services, Inc. at rank #16,086 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.9 claims per patent with primary concentration in E01B (PERMANENT WAY; PERMANENT-WAY TOOLS; MACHINES FOR MAKING RAILWAYS OF ALL KINDS). As a US Corporation, Herzog Railroad Services, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Herzog sits between Halo Microelectronics Co., Ltd. (18 patents, rank #16,082) and Hydragraphix Llc (18 patents, rank #16,090) - the closest US assignees by grant volume. The composite Innovation Score of 53.0/100 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 11 grants, compared with 7 in the 2015–2019 window, a +57% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Herzog Railroad Services, Inc.'s 16.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Herzog Railroad Services, Inc. against peers pursuing similar technology classes.

How to use this portfolio
Herzog's 18 grants land it in the top 9% by Innovation Score, but volume alone doesn't tell you where the strength sits.
Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
