Portfolio overview

Kabushiki Kaisha Toyota Jidoshokki has been granted 1,041 US utility patents between 2015 and 2025, placing Kabushiki Kaisha Toyota Jidoshokki at rank #435 across all assignees tracked by PlainPatent. This portfolio spans 191 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.3 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a Foreign Corporation, Kabushiki Kaisha Toyota Jidoshokki is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Kabushiki sits between Duke University (1,050 patents, rank #431) and Align Technology, Inc. (1,029 patents, rank #439) - the closest US assignees by grant volume. The composite Innovation Score of 58.6/100 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 447 grants, compared with 594 in the 2015–2019 window, a -25% 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. Kabushiki Kaisha Toyota Jidoshokki's 7.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kabushiki Kaisha Toyota Jidoshokki against peers pursuing similar technology classes.
