Portfolio overview
CONSTRUCTION RESEARCH & TECHNOLOGY GMBH has been granted 85 US utility patents between 2015 and 2025, placing CONSTRUCTION RESEARCH & TECHNOLOGY GMBH at rank #4,188 across all assignees tracked by PlainPatent. This portfolio spans 35 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.9 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 Foreign Corporation, CONSTRUCTION RESEARCH & TECHNOLOGY GMBH is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 52.7/100 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 30 grants, compared with 55 in the 2015–2019 window — a -45% 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. CONSTRUCTION RESEARCH & TECHNOLOGY GMBH's 19.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 35 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark CONSTRUCTION RESEARCH & TECHNOLOGY GMBH against peers pursuing similar technology classes.
