The verdict
Aisin holds 39 US patents across 41 technology areas — rank #8,154 of 50,000 tracked assignees.
AISIN TAKAOKA CO., LTD. has been granted 39 US utility patents between 2015 and 2025, placing AISIN TAKAOKA CO., LTD. at rank #8,154 across all assignees tracked by PlainPatent. This portfolio spans 41 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.5 claims per patent with primary concentration in C21D (MODIFYING THE PHYSICAL STRUCTURE OF FERROUS METALS; GENERAL DEVICES FOR HEAT TREATMENT OF FERROUS OR NON-FERROUS METALS OR ALLOYS; MAKING METAL MALLEABLE, e.g. BY DECARBURISATION OR TEMPERING). As a Foreign Corporation, AISIN TAKAOKA CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 42.3/100 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 13 grants, compared with 26 in the 2015–2019 window — a -50% 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 TAKAOKA CO., LTD.'s 7.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 41 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark AISIN TAKAOKA CO., LTD. against peers pursuing similar technology classes.

How to use this portfolio
Aisin's 39 grants land it in the top 31% by Innovation Score — but volume alone doesn't tell you where the strength sits.
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.
