Portfolio overview

Toshiba TEC Kabushiki Kaisha has been granted 3,280 US utility patents between 2015 and 2025, placing Toshiba TEC Kabushiki Kaisha at rank #112 across all assignees tracked by PlainPatent. This portfolio spans 146 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.8 claims per patent with primary concentration in G03G (ELECTROGRAPHY; ELECTROPHOTOGRAPHY; MAGNETOGRAPHY). As a Foreign Corporation, Toshiba TEC Kabushiki Kaisha is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Toshiba sits between Boston Scientific Scimed, Inc. (3,361 patents, rank #108) and Sumitomo Wiring Systems, Ltd. (3,190 patents, rank #116) - the closest US assignees by grant volume. The composite Innovation Score of 67.2/100 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 1,687 grants, compared with 1,593 in the 2015–2019 window, a +6% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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 TEC Kabushiki Kaisha's 14.8 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 TEC Kabushiki Kaisha against peers pursuing similar technology classes.
