Company patents
Enphase Energy, Inc.
Enphase Energy, Inc. demonstrates a primary focus on Power Distribution & Storage, accounting for over half of its portfolio (52.4%), yet this area has seen a significant decline in patenting activity in 2025 (-53.6% YoY) and so far in 2026 (-46.2% YoY), suggesting a potential shift in priorities despite its dominance. Surprisingly, while core electrical power categories are declining, there is an emerging focus on Electrical Measurement, which saw a remarkable 200.0% YoY growth so far in 2026, and a resurgence in Electric Vehicle Propulsion with 3 patents so far in 2026 after two years of no activity.
