The following content does not constitute legal advice and is for information exchange only. In some countries and regions, companies will take advantage of the diversity and differences in local intellectual property systems to build a more complex intellectual property protection network for the same product, thereby increasing the legal risks of their opponents in potential litigation. Common strategies and means include: 1. Multi-angle patent application a. Apply for patents for different technical points of the product, such as product design, technical process, manufacturing method, use, structural details, etc. b. By subdividing and decomposing technical solutions, a series of intertwined patent portfolios (the so-called "patent jungle" or "patent wall") are formed, which makes competitors face higher uncertainty and litigation costs when avoiding infringement risks. 2. Take advantage of differences in registration requirements in different countries a. Analyze the patent or trademark examination standards of the target countries and regions. Sometimes the same invention may meet different innovation requirements in different jurisdictions. b. In some countries, protection can be obtained through looser registration standards, while in other countries, the technical content may need to be supplemented or modified to obtain multiple versions of protection. 3. Multiple trademark registration strategy a. Use different marks, names, graphics (logos), slogans, etc. for the same product for trademark registration, because different countries have different focuses on trademark registration. b. With the help of international registration systems (such as the Madrid System), adopt unified or differentiated registration strategies in different countries to obtain optimal protection in localized operations. 4. International cooperation and unified application mechanism a. Utilize international application mechanisms, such as the Patent Cooperation Treaty (PCT), first submit international applications, and then enter the national phase according to the actual situation of each country. This approach can delay the time and make targeted adjustments in various places. b. International trademark registration (such as applications under the Madrid Agreement) can also help obtain protection in multiple jurisdictions simultaneously, but in actual operation, it is still necessary to pay attention to the specific examination and use regulations of each country. 5. Strategic "supplementary" and "improvement" applications a. On the basis of existing core patents or trademark protection, apply for "supplementary" or "improvement" patents in the future to expand the scope of protection and increase the difficulty for competitors to circumvent the core patents. b. At the same time, pay close attention to the layout of competitors, and apply for extended protection in a timely manner so that even if the core patent is questioned, you can rely on auxiliary patents to build a defense line. 6. Localized laws and professional support a. In combination with the advice of local legal advisors, formulate application strategies that are in line with the specific conditions of each country. b. Pay attention to precedents and review trends in judicial practice, and constantly adjust and improve the intellectual property portfolio to adapt to changes in the local legal environment. It should be emphasized that although the above means can strategically increase the complexity of opponents in legal proceedings, this strategy may also bring higher management and maintenance costs, and have an impact on the industry and market competition environment. Before adopting a similar strategy, it is recommended to evaluate the legal environment and actual business risks of the target market in detail, and consult professional legal advisors to ensure that the operation is within the scope of legality and compliance, while avoiding possible countermeasures or negative effects.
