Portfolio overview

Aisin Takaoka Co., Ltd. has been granted 39 US utility patents between 2015 and 2025, placing Aisin Takaoka Co., Ltd. at #8,155 of 50,000 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. By volume, Aisin sits between Iottie Inc. (40 patents, rank #8,150) and AYR Ltd. (39 patents, rank #8,158) - the closest US assignees by grant volume. The composite Innovation Score of 42.3/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Grant cadence records the difference between two grant-year windows. Between 2020 and 2024 the company received 12 grants, compared with 26 in the 2015–2019 window, a -54% shift in five-year grant velocity. Both windows cover five complete grant years; the latest PatentsView year is a partial release and is excluded from this comparison, though it still appears in the yearly table and chart below. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.

Claim depth and technology breadth describe this aggregate record. Aisin Takaoka Co., Ltd.'s 7.5 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 41 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
