Portfolio overview

Refractory Intellectual Property Gmbh & Co. KG has been granted 72 US utility patents between 2015 and 2025, placing Refractory Intellectual Property Gmbh & Co. KG at rank #4,832 across all assignees tracked by PlainPatent. This portfolio spans 23 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.5 claims per patent with primary concentration in B22D (CASTING OF METALS; CASTING OF OTHER SUBSTANCES BY THE SAME PROCESSES OR DEVICES). As a Foreign Corporation, Refractory Intellectual Property Gmbh & Co. KG is one of the more focused assignees in the PatentsView dataset. By volume, Refractory sits between Li-cor, Inc. (72 patents, rank #4,828) and Samyang Holdings Corporation (72 patents, rank #4,836) - the closest US assignees by grant volume. The composite Innovation Score of 45.1/100 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 34 grants, compared with 38 in the 2015–2019 window, a -11% 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. Refractory Intellectual Property Gmbh & Co. KG's 13.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 23 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Refractory Intellectual Property Gmbh & Co. KG against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
