Portfolio overview

TOSHIBA MEMORY CORPORATION has been granted 2,972 US utility patents between 2017 and 2024, placing TOSHIBA MEMORY CORPORATION at rank #128 across all assignees tracked by PlainPatent. This portfolio spans 114 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.6 claims per patent with primary concentration in G11C (STATIC STORES). As a Foreign Corporation, TOSHIBA MEMORY CORPORATION is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 62.1/100 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 1,304 grants, compared with 1,668 in the 2015–2019 window — a -22% 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. TOSHIBA MEMORY CORPORATION's 15.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, 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 TOSHIBA MEMORY CORPORATION against peers pursuing similar technology classes.
