Company patents
Novelis Inc.
Novelis Inc. shows a surprising shift away from its core materials innovation, with its largest category, Alloys (29.9% of portfolio), experiencing a significant decline of -30.8% in 2025 and -66.7% so far in 2026, alongside a -100.0% decline in Coating & Surface Treatment in 2024, only to rebound with 100.0% growth in 2026. This suggests a re-evaluation of its foundational material science focus, while an emerging focus on Batteries & Fuel Cells, which saw a 200.0% growth in 2025, indicates a potential diversification into energy storage solutions.
