Portfolio overview
Kabushiki Kaisha Toshiba has been granted 12,848 US utility patents between 2015 and 2025, placing Kabushiki Kaisha Toshiba at rank #24 across all assignees tracked by PlainPatent. This portfolio spans 347 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.4 claims per patent with primary concentration in G06F (ELECTRIC DIGITAL DATA PROCESSING). As a Foreign Corporation, Kabushiki Kaisha Toshiba is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 70.6/100 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 4,297 grants, compared with 8,551 in the 2015–2019 window — a -50% 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. Kabushiki Kaisha Toshiba's 13.4 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 Kabushiki Kaisha Toshiba against peers pursuing similar technology classes.
