Portfolio overview

Aisin Seiki Kabushiki Kaisha has been granted 1,137 US utility patents between 2015 and 2024, placing Aisin Seiki Kabushiki Kaisha at rank #389 across all assignees tracked by PlainPatent. This portfolio spans 171 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.1 claims per patent with primary concentration in B60R (VEHICLES, VEHICLE FITTINGS, OR VEHICLE PARTS, NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, Aisin Seiki Kabushiki Kaisha is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Aisin sits between Hitachi Astemo, Ltd. (1,145 patents, rank #385) and Orange (1,134 patents, rank #393) - the closest US assignees by grant volume. The composite Innovation Score of 54.7/100 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 291 grants, compared with 846 in the 2015–2019 window, a -66% 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. Aisin Seiki Kabushiki Kaisha's 8.1 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 Aisin Seiki Kabushiki Kaisha against peers pursuing similar technology classes.
