Portfolio overview

Andritz OY has been granted 49 US utility patents between 2015 and 2025, placing Andritz OY at rank #6,735 across all assignees tracked by PlainPatent. This portfolio spans 46 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.7 claims per patent with primary concentration in D21C (PRODUCTION OF CELLULOSE BY REMOVING NON-CELLULOSE SUBSTANCES FROM CELLULOSE-CONTAINING MATERIALS; REGENERATION OF PULPING LIQUORS; APPARATUS THEREFOR). As a Foreign Corporation, Andritz OY is one of the more focused assignees in the PatentsView dataset. By volume, Andritz sits between 4D Pharma Research Limited (49 patents, rank #6,731) and Bobrick Washroom Equipment, Inc. (49 patents, rank #6,739) - the closest US assignees by grant volume. The composite Innovation Score of 57.2/100 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 22 grants, compared with 27 in the 2015–2019 window, a -19% 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. Andritz OY's 16.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 46 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Andritz OY 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.
