Company patents
Dialog Semiconductor (UK) Limited
Dialog Semiconductor (UK) Limited's patent strategy appears to be undergoing a significant shift, with a surprising and near-complete cessation of new patent filings across almost all categories in 2025, including its dominant area of Power Conversion (DC/AC, DC/DC) which previously constituted 60.9% of its portfolio but saw a -100.0% YoY decline in 2025. This widespread decline, with only Magnets & Inductors maintaining a stable filing rate (0% YoY) and Amplifiers showing a slight resurgence in 2025 after a -100.0% drop in 2024, suggests a dramatic re-evaluation or divestment of its intellectual property strategy.
