Portfolio overview

Aisin Corporation has been granted 543 US utility patents between 2015 and 2025, placing Aisin Corporation at rank #837 across all assignees tracked by PlainPatent. This portfolio spans 131 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.1 claims per patent with primary concentration in H02K (DYNAMO-ELECTRIC MACHINES). As a Foreign Corporation, Aisin Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Aisin sits between GREE Holdings, Inc. (549 patents, rank #833) and Xiamen Tianma Micro-electronics Co., Ltd. (543 patents, rank #841) - the closest US assignees by grant volume. The composite Innovation Score of 72.2/100 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 542 grants, compared with 1 in the 2015–2019 window, a +54100% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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 Corporation's 9.1 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 Corporation 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.
