Portfolio overview

FUJITSU SEMICONDUCTOR LIMITED has been granted 185 US utility patents between 2015 and 2020, placing FUJITSU SEMICONDUCTOR LIMITED at rank #2,129 across all assignees tracked by PlainPatent. This portfolio spans 33 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, FUJITSU SEMICONDUCTOR LIMITED is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 45.5/100 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 4 grants, compared with 181 in the 2015–2019 window — a -98% 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. FUJITSU SEMICONDUCTOR LIMITED's 12.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 33 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark FUJITSU SEMICONDUCTOR LIMITED against peers pursuing similar technology classes.
