Portfolio overview

Sumitomo Electric Device Innovations, Inc. has been granted 266 US utility patents between 2015 and 2025, placing Sumitomo Electric Device Innovations, Inc. at rank #1,560 across all assignees tracked by PlainPatent. This portfolio spans 36 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.5 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a Foreign Corporation, Sumitomo Electric Device Innovations, Inc. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 51.5/100 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 123 grants, compared with 143 in the 2015–2019 window — a -14% 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. Sumitomo Electric Device Innovations, Inc.'s 10.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 36 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sumitomo Electric Device Innovations, Inc. against peers pursuing similar technology classes.
