Portfolio overview

Essex Furukawa Magnet WIRE Japan Co., Ltd. has been granted 11 US utility patents between 2021 and 2025, placing Essex Furukawa Magnet WIRE Japan Co., Ltd. at rank #24,254 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.0 claims per patent with primary concentration in H01B (CABLES; CONDUCTORS; INSULATORS; SELECTION OF MATERIALS FOR THEIR CONDUCTIVE, INSULATING OR DIELECTRIC PROPERTIES). As a Foreign Corporation, Essex Furukawa Magnet WIRE Japan Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Essex sits between EPG (engineered Nanoproducts Germany) Ag (11 patents, rank #24,250) and Eurotech S.p.a. (11 patents, rank #24,258) - the closest US assignees by grant volume. The composite Innovation Score of 39.6/100 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. Historical data spans 2021 through 2025, with 11 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Essex Furukawa Magnet WIRE Japan Co., Ltd.'s 10.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Essex Furukawa Magnet WIRE Japan Co., Ltd. against peers pursuing similar technology classes.
