Portfolio overview

Element Six Limited has been granted 95 US utility patents between 2015 and 2024, placing Element Six Limited at rank #3,805 across all assignees tracked by PlainPatent. This portfolio spans 48 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.3 claims per patent with primary concentration in C22C (ALLOYS). As a Foreign Corporation, Element Six Limited is one of the more focused assignees in the PatentsView dataset. By volume, Element sits between Cortica Ltd. (95 patents, rank #3,801) and Hyosung Heavy Industries Corporation (95 patents, rank #3,809) - the closest US assignees by grant volume. The composite Innovation Score of 52.4/100 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 16 grants, compared with 79 in the 2015–2019 window, a -80% 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. Element Six Limited'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 48 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Element Six Limited 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.
