Portfolio overview

Toshiba Infrastructure Systems & Solutions Corporation has been granted 284 US utility patents between 2018 and 2025, placing Toshiba Infrastructure Systems & Solutions Corporation at rank #1,464 across all assignees tracked by PlainPatent. This portfolio spans 107 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.8 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a Foreign Corporation, Toshiba Infrastructure Systems & Solutions Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Toshiba sits between VIA Alliance Semiconductor Co., Ltd. (285 patents, rank #1,460) and Ab Initio Technology Llc (283 patents, rank #1,468) - the closest US assignees by grant volume. The composite Innovation Score of 55.9/100 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 254 grants, compared with 30 in the 2015–2019 window, a +747% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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 Infrastructure Systems & Solutions Corporation's 9.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, 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 Infrastructure Systems & Solutions Corporation against peers pursuing similar technology classes.
