Portfolio overview

FURUKAWA CO., LTD. has been granted 24 US utility patents between 2015 and 2025, placing FURUKAWA CO., LTD. at rank #12,446 across all assignees tracked by PlainPatent. This portfolio spans 28 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.0 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, FURUKAWA CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 40.1/100 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 14 grants, compared with 10 in the 2015–2019 window, a +40% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. FURUKAWA CO., LTD.'s 11.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 28 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark FURUKAWA CO., LTD. against peers pursuing similar technology classes.
