Company patents

SUNPOWER CORPORATION

SUNPOWER CORPORATION's patent strategy shows a surprising shift, with significant declines across nearly all categories in 2025, including its core "Photovoltaic (Solar Cells)" category which dropped by 94.1% after a 41.7% growth in 2024. This widespread decline, including a 100% drop in "Electronic Design Automation (CAD/EDA)" after a 100% growth in 2024, suggests a dramatic re-evaluation or divestment of its patenting efforts, rather than a focused shift to new emerging areas.
