Portfolio overview

Kwansei Gakuin Educational Foundation has been granted 57 US utility patents between 2015 and 2025, placing Kwansei Gakuin Educational Foundation at #5,954 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 31 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.9 claims per patent with primary concentration in C30B (SINGLE-CRYSTAL GROWTH ; UNIDIRECTIONAL SOLIDIFICATION OF EUTECTIC MATERIAL OR UNIDIRECTIONAL DEMIXING OF EUTECTOID MATERIAL; REFINING BY ZONE-MELTING OF MATERIAL ; PRODUCTION OF A HOMOGENEOUS POLYCRYS). As a Foreign Corporation, Kwansei Gakuin Educational Foundation is one of the more focused assignees in the PatentsView dataset. By volume, Kwansei sits between Ironburg Inventions Limited (57 patents, rank #5,948) and Mastercard Technologies Canada ULC (57 patents, rank #5,956) - the closest US assignees by grant volume. The composite Innovation Score of 56.4/100 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 38 grants, compared with 7 in the 2015–2019 window, a +443% 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. Kwansei Gakuin Educational Foundation's 13.9 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 31 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
