Portfolio overview

Furuno Electric Company Limited has been granted 314 US utility patents between 2015 and 2025, placing Furuno Electric Company Limited at rank #1,343 across all assignees tracked by PlainPatent. This portfolio spans 66 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.2 claims per patent with primary concentration in G01S (RADIO DIRECTION-FINDING; RADIO NAVIGATION; DETERMINING DISTANCE OR VELOCITY BY USE OF RADIO WAVES; LOCATING OR PRESENCE-DETECTING BY USE OF THE REFLECTION OR RERADIATION OF RADIO WAVES; ANALOGOUS ARRA). As a Foreign Corporation, Furuno Electric Company Limited is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Furuno sits between THE University OF Akron (316 patents, rank #1,339) and Hong Kong Applied Science And Technology Research Institute Company Limited (313 patents, rank #1,347) - the closest US assignees by grant volume. The composite Innovation Score of 64.0/100 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 154 grants, compared with 160 in the 2015–2019 window, a -4% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Furuno Electric Company Limited's 14.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 66 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Furuno Electric Company Limited against peers pursuing similar technology classes.
