Portfolio overview
Stratospheric Platforms Ltd has been granted 10 US utility patents between 2018 and 2024, placing Stratospheric Platforms Ltd at rank #27,528 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.9 claims per patent with primary concentration in H04B (TRANSMISSION). As a Foreign Corporation, Stratospheric Platforms Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Stratospheric sits between Stopak India Pvt. Ltd. (10 patents, rank #27,524) and Stroz Friedberg, Llc (10 patents, rank #27,532) - the closest US assignees by grant volume. The composite Innovation Score of 34.8/100 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 7 grants, compared with 3 in the 2015–2019 window, a +133% 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. Stratospheric Platforms Ltd's 20.9 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 6 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Stratospheric Platforms Ltd against peers pursuing similar technology classes.
