Portfolio overview

Huf Hülsbeck & Fürst Gmbh & Co. KG has been granted 217 US utility patents between 2015 and 2025, placing Huf Hülsbeck & Fürst Gmbh & Co. KG at rank #1,854 across all assignees tracked by PlainPatent. This portfolio spans 71 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.3 claims per patent with primary concentration in E05B (LOCKS; ACCESSORIES THEREFOR; HANDCUFFS). As a Foreign Corporation, Huf Hülsbeck & Fürst Gmbh & Co. KG is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Huf sits between Steelseries Aps (218 patents, rank #1,850) and Solarcity Corporation (217 patents, rank #1,858) - the closest US assignees by grant volume. The composite Innovation Score of 56.5/100 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 74 grants, compared with 143 in the 2015–2019 window, a -48% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Huf Hülsbeck & Fürst Gmbh & Co. KG's 16.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 71 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Huf Hülsbeck & Fürst Gmbh & Co. KG against peers pursuing similar technology classes.
