Portfolio overview

Hengst SE & Co. KG has been granted 16 US utility patents between 2015 and 2020, placing Hengst SE & Co. KG at rank #17,752 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.9 claims per patent with primary concentration in B01D (SEPARATION). As a Foreign Corporation, Hengst SE & Co. KG is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 32.9/100 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 1 grants, compared with 15 in the 2015–2019 window, a -93% 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. Hengst SE & Co. KG's 20.9 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hengst SE & Co. KG against peers pursuing similar technology classes.

Guides to patent portfolio analysis

How to use this portfolio

Hengst's 16 grants land it in the top 57% by Innovation Score, but volume alone doesn't tell you where the strength sits.
