Company patents
Rolls-Royce Corporation
Rolls-Royce Corporation's patent strategy reveals a surprising shift, with its core "Steam / Gas Turbines" and "Gas Turbine Plants" categories, representing 37.3% and 21.6% of its portfolio respectively, showing significant declines in 2024 and 2025, and continued sharp drops so far in 2026. This suggests a potential strategic pivot away from traditional turbine technologies, despite a strong resurgence in "Additive Manufacturing (3D Printing)" (125.0% YoY growth in 2025) and "Powder Metallurgy" (136.4% YoY growth in 2025), indicating an emerging focus on advanced manufacturing processes, while "Electric Motors & Generators" also saw rapid growth of 150.0% in 2024.
