Portfolio overview

Furukawa Electric Co., Ltd. has been granted 883 US utility patents between 2015 and 2025, placing Furukawa Electric Co., Ltd. at rank #510 across all assignees tracked by PlainPatent. This portfolio spans 176 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.4 claims per patent with primary concentration in G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS). As a Foreign Corporation, Furukawa Electric Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Furukawa sits between Zhejiang University (888 patents, rank #506) and IMEC VZW (876 patents, rank #514) - the closest US assignees by grant volume. The composite Innovation Score of 61.4/100 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 472 grants, compared with 411 in the 2015–2019 window, a +15% 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 Electric Co., Ltd.'s 11.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Furukawa Electric Co., Ltd. against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
