Portfolio overview

Stanley Electric Co., Ltd. has been granted 575 US utility patents between 2015 and 2025, placing Stanley Electric Co., Ltd. at rank #800 across all assignees tracked by PlainPatent. This portfolio spans 86 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.0 claims per patent with primary concentration in F21S (NON-PORTABLE LIGHTING DEVICES; SYSTEMS THEREOF; VEHICLE LIGHTING DEVICES SPECIALLY ADAPTED FOR VEHICLE EXTERIORS). As a Foreign Corporation, Stanley Electric Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 57.0/100 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 261 grants, compared with 314 in the 2015–2019 window — a -17% 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. Stanley Electric Co., Ltd.'s 12.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 86 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Stanley Electric Co., Ltd. against peers pursuing similar technology classes.
