Portfolio overview

TOSHIBA MATERIALS CO., LTD. has been granted 176 US utility patents between 2015 and 2025, placing TOSHIBA MATERIALS CO., LTD. at rank #2,233 across all assignees tracked by PlainPatent. This portfolio spans 79 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.2 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a Foreign Corporation, TOSHIBA MATERIALS CO., LTD. is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 54.3/100 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 83 grants, compared with 93 in the 2015–2019 window — a -11% 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 MATERIALS CO., LTD.'s 13.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 79 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark TOSHIBA MATERIALS CO., LTD. against peers pursuing similar technology classes.
