Portfolio overview

Westinghouse Air Brake Technologies Corporation has been granted 211 US utility patents between 2016 and 2025, placing Westinghouse Air Brake Technologies Corporation at rank #1,904 across all assignees tracked by PlainPatent. This portfolio spans 87 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.7 claims per patent with primary concentration in B61L (GUIDING RAILWAY TRAFFIC; ENSURING THE SAFETY OF RAILWAY TRAFFIC). As a US Corporation, Westinghouse Air Brake Technologies Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Westinghouse sits between GE Energy Power Conversion Technology Limited (211 patents, rank #1,900) and Baylor College Of Medicine (210 patents, rank #1,908) - the closest US assignees by grant volume. The composite Innovation Score of 62.4/100 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. Between 2020 and 2025 the company received 155 grants, compared with 56 in the 2015–2019 window, a +177% 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. Westinghouse Air Brake Technologies Corporation's 18.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 87 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Westinghouse Air Brake Technologies Corporation against peers pursuing similar technology classes.
