Toshiba Electronic Devices & Storage Corporation

Toshiba Electronic Devices & Storage Corporation has been granted 1,454 US utility patents between 2018 and 2025, placing Toshiba Electronic Devices & Storage Corporation at rank #294 across all assignees tracked by PlainPatent. This portfolio spans 91 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.3 claims per patent with primary concentration in G11B (INFORMATION STORAGE BASED ON RELATIVE MOVEMENT BETWEEN RECORD CARRIER AND TRANSDUCER). As a Foreign Corporation, Toshiba Electronic Devices & Storage Corporation is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 66.7/100 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 1,349 grants, compared with 105 in the 2015–2019 window — a +1185% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Toshiba Electronic Devices & Storage Corporation's 13.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 91 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Toshiba Electronic Devices & Storage Corporation against peers pursuing similar technology classes.
