Rio Tinto Alcan International Limited

Rio Tinto Alcan International Limited has been granted 36 US utility patents between 2015 and 2025, placing Rio Tinto Alcan International Limited at rank #8,906 across all assignees tracked by PlainPatent. This portfolio spans 28 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.8 claims per patent with primary concentration in C25C (PROCESSES FOR THE ELECTROLYTIC PRODUCTION, RECOVERY OR REFINING OF METALS; APPARATUS THEREFOR). As a Foreign Corporation, Rio Tinto Alcan International Limited is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 45.4/100 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 12 grants, compared with 24 in the 2015–2019 window — a -50% 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. Rio Tinto Alcan International Limited's 20.8 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, 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 Rio Tinto Alcan International Limited against peers pursuing similar technology classes.
