Portfolio overview
West Affum Holdings DAC has been granted 98 US utility patents between 2022 and 2025, placing West Affum Holdings DAC at rank #3,721 across all assignees tracked by PlainPatent. This portfolio spans 21 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.9 claims per patent with primary concentration in A61N (ELECTROTHERAPY; MAGNETOTHERAPY; RADIATION THERAPY; ULTRASOUND THERAPY). As a Foreign Corporation, West Affum Holdings DAC is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 63.4/100 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. Historical data spans 2022 through 2025, with 98 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. West Affum Holdings DAC's 18.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 21 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark West Affum Holdings DAC against peers pursuing similar technology classes.
