Portfolio overview

CLEARSTREAM TECHNOLOGIES LIMITED has been granted 37 US utility patents between 2018 and 2024, placing CLEARSTREAM TECHNOLOGIES LIMITED at rank #8,552 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.7 claims per patent with primary concentration in A61M (DEVICES FOR INTRODUCING MEDIA INTO, OR ONTO, THE BODY ; DEVICES FOR TRANSDUCING BODY MEDIA OR FOR TAKING MEDIA FROM THE BODY ; DEVICES FOR PRODUCING OR ENDING SLEEP OR STUPOR). As a Foreign Corporation, CLEARSTREAM TECHNOLOGIES LIMITED is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 46.3/100 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 31 grants, compared with 6 in the 2015–2019 window — a +417% 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. CLEARSTREAM TECHNOLOGIES LIMITED's 13.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark CLEARSTREAM TECHNOLOGIES LIMITED against peers pursuing similar technology classes.
