Portfolio overview

Kelheim Fibres Gmbh has been granted 7 US utility patents between 2016 and 2024, placing Kelheim Fibres Gmbh at rank #36,077 across all assignees tracked by PlainPatent. This portfolio spans 17 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.6 claims per patent with primary concentration in D01F (CHEMICAL FEATURES IN THE MANUFACTURE OF ARTIFICIAL FILAMENTS, THREADS, FIBRES, BRISTLES OR RIBBONS; APPARATUS SPECIALLY ADAPTED FOR THE MANUFACTURE OF CARBON FILAMENTS). As a Foreign Corporation, Kelheim Fibres Gmbh is one of the more focused assignees in the PatentsView dataset. By volume, Kelheim sits between KECK Graduate Institute OF Applied LIFE Sciences (7 patents, rank #36,073) and KEYA Medical Technology Co., Ltd. (7 patents, rank #36,081) - the closest US assignees by grant volume. The composite Innovation Score of 36.1/100 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 3 in the 2015–2019 window, a +33% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Kelheim Fibres Gmbh's 16.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 17 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kelheim Fibres Gmbh against peers pursuing similar technology classes.
