Portfolio overview

Adolf Kühner Ag has been granted 5 US utility patents between 2019 and 2023, placing Adolf Kühner Ag at rank #44,402 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.2 claims per patent with primary concentration in C12M (APPARATUS FOR ENZYMOLOGY OR MICROBIOLOGY; APPARATUS FOR CULTURING MICROORGANISMS FOR PRODUCING BIOMASS, FOR GROWING CELLS OR FOR OBTAINING FERMENTATION OR METABOLIC PRODUCTS, i.e. BIOREACTORS OR FERME). As a Foreign Corporation, Adolf Kühner Ag is one of the more focused assignees in the PatentsView dataset. By volume, Adolf sits between Adhex Technologies (5 patents, rank #44,398) and Advanced Flexible Composites, Inc. (5 patents, rank #44,406) - the closest US assignees by grant volume. The composite Innovation Score of 35.0/100 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 4 grants, compared with 1 in the 2015–2019 window, a +300% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Adolf Kühner Ag's 18.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Adolf Kühner Ag against peers pursuing similar technology classes.
