Portfolio overview

Advanced Ceramic Fibers, Llc has been granted 10 US utility patents between 2015 and 2024, placing Advanced Ceramic Fibers, Llc at rank #25,648 across all assignees tracked by PlainPatent. This portfolio spans 17 distinct Cooperative Patent Classification (CPC) subclasses, averaging 22.8 claims per patent with primary concentration in C04B (LIME, MAGNESIA; SLAG; CEMENTS; COMPOSITIONS THEREOF, e.g. MORTARS, CONCRETE OR LIKE BUILDING MATERIALS; ARTIFICIAL STONE ; CERAMICS ; REFRACTORIES; TREATMENT OF NATURAL STONE). As a US Corporation, Advanced Ceramic Fibers, Llc is one of the more focused assignees in the PatentsView dataset. By volume, Advanced sits between Adaptive Sensory Technology, Inc. (10 patents, rank #25,644) and Aerogroup International Holdings Llc (10 patents, rank #25,652) - the closest US assignees by grant volume. The composite Innovation Score of 38.2/100 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 3 grants, compared with 7 in the 2015–2019 window, a -57% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Advanced Ceramic Fibers, Llc's 22.8 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 17 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Advanced Ceramic Fibers, Llc against peers pursuing similar technology classes.
