The collision of intellectual property and management cases has sparked the content of this book. Drawing from a selection of 11 typical cases handled by Professor TAO Xinliang, the first dean of the Intellectual Property School at Dalian University of Technology and a renowned domestic intellectual property expert, the book meticulously categorizes these cases into trademark, patent, and copyright sections based on primary and secondary data. Each case is presented in a structured format of "narrative," "legal," and "business" sections, providing interpretations from legal and business perspectives while conducting multidimensional analysis and research. Concluding each case with insights and distilled management lessons, this book aims to benefit readers with a background or interest in areas such as enterprise management, intellectual property management, and law.
