Portfolio overview

FUJI Electric Co., Ltd. has been granted 2,654 US utility patents between 2015 and 2025, placing FUJI Electric Co., Ltd. at rank #142 across all assignees tracked by PlainPatent. This portfolio spans 195 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.0 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a Foreign Corporation, FUJI Electric Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, FUJI sits between Rohm Co., Ltd. (2,753 patents, rank #138) and Arm Limited (2,613 patents, rank #146) - the closest US assignees by grant volume. The composite Innovation Score of 63.7/100 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 1,250 grants, compared with 1,404 in the 2015–2019 window, a -11% 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. FUJI Electric Co., Ltd.'s 12.0 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 FUJI 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.
