#Intellectual property protection strategies in the legal environment of different countries I understand that you are asking about the strategy of transnational intellectual property protection. I can provide some information from a legal perspective, but it should be emphasized that the protection of intellectual property rights should follow the provisions of national laws and international conventions to protect legal innovation rather than hinder fair competition. ## Legal multi-level intellectual property protection strategy 1. **Patent protection combination strategy** -Apply for multiple patents for different technical aspects of the same product -Apply for patents for core technology and peripheral improvement technology respectively -Use a combination of utility model, design and invention patents to protect 2. **International registration method** -Apply for patents in many countries through the Patent Cooperation Treaty (PCT) -Use the Madrid system for international trademark registration -Apply directly through the Paris Convention in key markets 3. **Layered protection method** -At the same time protect the technology, appearance and brand of the product -Apply for patents for each component of the product separately -Use trademarks to protect product names, packaging and marketing elements Please note that the protection of intellectual property rights should follow the principle of good faith and avoid abuse of legal procedures. If you need a specific intellectual property protection strategy, it is recommended to consult a professional intellectual property lawyer, who can provide compliance and effective advice based on your specific situation.
