Portfolio overview

Railway Technical Research Institute has been granted 10 US utility patents between 2015 and 2024, placing Railway Technical Research Institute at rank #27,223 across all assignees tracked by PlainPatent. This portfolio spans 20 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.8 claims per patent with primary concentration in B61H (BRAKES OR OTHER RETARDING DEVICES SPECIALLY ADAPTED FOR RAIL VEHICLES; ARRANGEMENT OR DISPOSITION THEREOF IN RAIL VEHICLES). As a Foreign Corporation, Railway Technical Research Institute is one of the more focused assignees in the PatentsView dataset. By volume, Railway sits between RAD AI, Inc. (10 patents, rank #27,219) and Recombinetics, Inc. (10 patents, rank #27,227) - the closest US assignees by grant volume. The composite Innovation Score of 37.2/100 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 3 grants, compared with 7 in the 2015–2019 window, a -57% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Railway Technical Research Institute's 10.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 20 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Railway Technical Research Institute against peers pursuing similar technology classes.
