USPTO PatentsView assignee record - 9 granted patents across 8 technology areas, active 2020–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: B61D (BODY DETAILS OR KINDS OF RAILWAY VEHICLES).
The verdict
Stadler holds 9 US patents across 8 technology areas, rank #30,240 of 50,000 tracked assignees.
Stadler Rail Ag has been granted 9 US utility patents between 2020 and 2025, placing Stadler Rail Ag at rank #30,240 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.8 claims per patent with primary concentration in B61D (BODY DETAILS OR KINDS OF RAILWAY VEHICLES). As a Foreign Corporation, Stadler Rail Ag is one of the more focused assignees in the PatentsView dataset. By volume, Stadler sits between Sportsbeams Lighting, Inc. (9 patents, rank #30,236) and Star Institute Of Intelligent Systems (9 patents, rank #30,244) - the closest US assignees by grant volume. The composite Innovation Score of 31.4/100 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. Historical data spans 2020 through 2025, with 9 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Stadler Rail Ag's 16.8 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 Stadler Rail Ag against peers pursuing similar technology classes.

How to use this portfolio
Stadler's 9 grants land it in the top 62% 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.
