Portfolio overview

Rockwool International A/s has been granted 97 US utility patents between 2015 and 2024, placing Rockwool International A/s at rank #3,746 across all assignees tracked by PlainPatent. This portfolio spans 68 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.4 claims per patent with primary concentration in E04B (GENERAL BUILDING CONSTRUCTIONS; WALLS, e.g. PARTITIONS; ROOFS; FLOORS; CEILINGS; INSULATION OR OTHER PROTECTION OF BUILDINGS). As a Foreign Corporation, Rockwool International A/s is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Rockwool sits between Novell, Inc. (97 patents, rank #3,742) and Sealed Air Corporation (us) (97 patents, rank #3,750) - the closest US assignees by grant volume. The composite Innovation Score of 52.5/100 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 44 grants, compared with 53 in the 2015–2019 window, a -17% 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. Rockwool International A/s's 14.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 68 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Rockwool International A/s 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.
