TOKYO ELECTRON LIMITED

TOKYO ELECTRON LIMITED has been granted 5,061 US utility patents between 2015 and 2025, placing TOKYO ELECTRON LIMITED at rank #70 across all assignees tracked by PlainPatent. This portfolio spans 194 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.5 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a Foreign Corporation, TOKYO ELECTRON LIMITED is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 69.8/100 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 3,064 grants, compared with 1,997 in the 2015–2019 window — a +53% 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. TOKYO ELECTRON LIMITED's 12.5 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 TOKYO ELECTRON LIMITED against peers pursuing similar technology classes.
