Portfolio overview

Fox Head, Inc. has been granted 19 US utility patents between 2017 and 2025, placing Fox Head, Inc. at rank #15,295 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.6 claims per patent with primary concentration in A43B (CHARACTERISTIC FEATURES OF FOOTWEAR; PARTS OF FOOTWEAR). As a US Corporation, Fox Head, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Fox sits between Flytrex Aviation Ltd. (19 patents, rank #15,291) and Freeport-mcmoran, Inc. (19 patents, rank #15,299) - the closest US assignees by grant volume. The composite Innovation Score of 40.2/100 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 10 grants, compared with 9 in the 2015–2019 window, a +11% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. The US 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. Fox Head, Inc.'s 13.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 8 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Fox Head, Inc. against peers pursuing similar technology classes.
