Portfolio overview

Hollingsworth & Vose Company has been granted 88 US utility patents between 2015 and 2025, placing Hollingsworth & Vose Company at rank #4,084 across all assignees tracked by PlainPatent. This portfolio spans 20 distinct Cooperative Patent Classification (CPC) subclasses, averaging 23.8 claims per patent with primary concentration in B01D (SEPARATION). As a US Corporation, Hollingsworth & Vose Company is one of the more focused assignees in the PatentsView dataset. By volume, Hollingsworth sits between Derrick Corporation (88 patents, rank #4,080) and Joy Global Surface Mining Inc (88 patents, rank #4,088) - the closest US assignees by grant volume. The composite Innovation Score of 50.5/100 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 45 grants, compared with 43 in the 2015–2019 window, a +5% 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. Hollingsworth & Vose Company's 23.8 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 20 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hollingsworth & Vose Company against peers pursuing similar technology classes.
