Portfolio overview

ADEY Holdings (2008) Limited has been granted 67 US utility patents between 2015 and 2025, placing ADEY Holdings (2008) Limited at rank #5,135 across all assignees tracked by PlainPatent. This portfolio spans 17 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.4 claims per patent with primary concentration in B03C (MAGNETIC OR ELECTROSTATIC SEPARATION OF SOLID MATERIALS FROM SOLID MATERIALS OR FLUIDS; SEPARATION BY HIGH-VOLTAGE ELECTRIC FIELDS). As a Foreign Corporation, ADEY Holdings (2008) Limited is one of the more focused assignees in the PatentsView dataset. By volume, ADEY sits between I4f Licensing Nv (68 patents, rank #5,131) and Areva NP (67 patents, rank #5,139) - the closest US assignees by grant volume. The composite Innovation Score of 45.6/100 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 35 grants, compared with 32 in the 2015–2019 window, a +9% 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. ADEY Holdings (2008) Limited's 8.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 17 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ADEY Holdings (2008) Limited against peers pursuing similar technology classes.
