Portfolio overview

Valmet AB has been granted 98 US utility patents between 2015 and 2025, placing Valmet AB at rank #3,720 across all assignees tracked by PlainPatent. This portfolio spans 50 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.3 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, Valmet AB is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Valmet sits between Samumed, Llc (98 patents, rank #3,716) and Arlo Technologies, Inc. (97 patents, rank #3,724) - the closest US assignees by grant volume. The composite Innovation Score of 61.9/100 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. Between 2020 and 2025 the company received 64 grants, compared with 34 in the 2015–2019 window, a +88% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Valmet AB's 13.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 50 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Valmet AB 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.
