Portfolio overview

Asahi Yukizai Corporation has been granted 39 US utility patents between 2016 and 2025, placing Asahi Yukizai Corporation at #8,161 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.9 claims per patent with primary concentration in F16K (VALVES; TAPS; COCKS; ACTUATING-FLOATS; DEVICES FOR VENTING OR AERATING). As a Foreign Corporation, Asahi Yukizai Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Asahi sits between Nchain Holdings Ltd (40 patents, rank #8,151) and Air Liquide Advanced Technologies U.s. Llc (39 patents, rank #8,159) - the closest US assignees by grant volume. The composite Innovation Score of 36.5/100 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 31 grants, compared with 6 in the 2015–2019 window, a +417% 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. Asahi Yukizai Corporation's 6.9 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 15 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.
