Portfolio overview

Rockwool A/s has been granted 33 US utility patents between 2023 and 2025, placing Rockwool A/s at rank #9,601 across all assignees tracked by PlainPatent. This portfolio spans 41 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.8 claims per patent with primary concentration in D04H (MAKING TEXTILE FABRICS, e.g. FROM FIBRES OR FILAMENTARY MATERIAL ; FABRICS MADE BY SUCH PROCESSES OR APPARATUS, e.g. FELTS, NON-WOVEN FABRICS; COTTON-WOOL; WADDING ; ; NON-WOVEN FABRICS FROM STAPLE FI). As a Foreign Corporation, Rockwool A/s is one of the more focused assignees in the PatentsView dataset. By volume, Rockwool sits between Redbox Automated Retail, Llc (33 patents, rank #9,597) and Rheinische Friedrich-wilhems-universitaet Bonn (33 patents, rank #9,605) - the closest US assignees by grant volume. The composite Innovation Score of 64.9/100 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. Historical data spans 2023 through 2025, with 33 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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 A/s's 16.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 41 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Rockwool A/s against peers pursuing similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
