Toshiba Lighting & Technology Corporation

Toshiba Lighting & Technology Corporation has been granted 121 US utility patents between 2015 and 2025, placing Toshiba Lighting & Technology Corporation at rank #3,128 across all assignees tracked by PlainPatent. This portfolio spans 28 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.2 claims per patent with primary concentration in H05B (ELECTRIC HEATING; ELECTRIC LIGHT SOURCES NOT OTHERWISE PROVIDED FOR; CIRCUIT ARRANGEMENTS FOR ELECTRIC LIGHT SOURCES, IN GENERAL). As a Foreign Corporation, Toshiba Lighting & Technology Corporation is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 46.5/100 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 38 grants, compared with 83 in the 2015–2019 window — a -54% 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 Lighting & Technology Corporation'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 28 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Toshiba Lighting & Technology Corporation against peers pursuing similar technology classes.
