Portfolio overview

Torotrak (development) Limited has been granted 9 US utility patents between 2015 and 2017, placing Torotrak (development) Limited at rank #30,420 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.3 claims per patent with primary concentration in F16H (GEARING). As a Foreign Corporation, Torotrak (development) Limited is one of the more focused assignees in the PatentsView dataset. By volume, Torotrak sits between Tokenex, Inc. (9 patents, rank #30,416) and Toyota Mapmaster Incorporated (9 patents, rank #30,424) - the closest US assignees by grant volume. The composite Innovation Score of 28.9/100 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 0 grants, compared with 9 in the 2015–2019 window, a -100% 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. Torotrak (development) Limited's 15.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Torotrak (development) Limited against peers pursuing similar technology classes.
