Kokusai Electric Corporation

Kokusai Electric Corporation has been granted 587 US utility patents between 2018 and 2025, placing Kokusai Electric Corporation at rank #781 across all assignees tracked by PlainPatent. This portfolio spans 52 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.6 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a Foreign Corporation, Kokusai Electric Corporation is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 62.7/100 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 517 grants, compared with 70 in the 2015–2019 window — a +639% 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. Kokusai Electric Corporation's 13.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 52 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kokusai Electric Corporation against peers pursuing similar technology classes.
