Portfolio overview

West Affum Holdings Corp. has been granted 112 US utility patents between 2015 and 2022, placing West Affum Holdings Corp. at rank #3,337 across all assignees tracked by PlainPatent. This portfolio spans 17 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.5 claims per patent with primary concentration in A61N (ELECTROTHERAPY; MAGNETOTHERAPY; RADIATION THERAPY; ULTRASOUND THERAPY). As a Foreign Corporation, West Affum Holdings Corp. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 45.5/100 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 67 grants, compared with 45 in the 2015–2019 window — a +49% 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. West Affum Holdings Corp.'s 19.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 17 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark West Affum Holdings Corp. against peers pursuing similar technology classes.
