Portfolio overview

Elkem ASA has been granted 20 US utility patents between 2019 and 2025, placing Elkem ASA at rank #14,582 across all assignees tracked by PlainPatent. This portfolio spans 28 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.1 claims per patent with primary concentration in C21C (PROCESSING OF PIG-IRON, e.g. REFINING, MANUFACTURE OF WROUGHT-IRON OR STEEL; TREATMENT IN MOLTEN STATE OF FERROUS ALLOYS). As a Foreign Corporation, Elkem ASA is one of the more focused assignees in the PatentsView dataset. By volume, Elkem sits between Duality Technologies, Inc. (20 patents, rank #14,578) and Escape Fitness Limited (20 patents, rank #14,586) - the closest US assignees by grant volume. The composite Innovation Score of 50.3/100 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 18 grants, compared with 2 in the 2015–2019 window, a +800% 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. Elkem ASA's 16.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 28 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Elkem ASA 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.
