Portfolio overview

Toyoda IRON Works Co., Ltd. has been granted 97 US utility patents between 2015 and 2025, placing Toyoda IRON Works Co., Ltd. at rank #3,755 across all assignees tracked by PlainPatent. This portfolio spans 57 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.8 claims per patent with primary concentration in G05G (CONTROL DEVICES OR SYSTEMS INSOFAR AS CHARACTERISED BY MECHANICAL FEATURES ONLY). As a Foreign Corporation, Toyoda IRON Works Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Toyoda sits between Sirius XM Radio Inc. (97 patents, rank #3,751) and Universite PAUL Sabatier—toulouse III (97 patents, rank #3,759) - the closest US assignees by grant volume. The composite Innovation Score of 51.2/100 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 34 grants, compared with 63 in the 2015–2019 window, a -46% 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. Toyoda IRON Works Co., Ltd.'s 6.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 57 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Toyoda IRON Works Co., Ltd. against peers pursuing similar technology classes.

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.
