By taking advantage of the differences in patent application, disclosure and protection systems among countries, and carefully designing patent strategies, we can ensure that technical details are kept confidential in core markets for a long time, thereby extending the product's global market competition period. The following are some common strategies and ideas. However, it should be noted that any strategy must be implemented within the scope permitted by the laws of each country to avoid violating the law or causing doubts from regulators. 1. Phased patent application and disclosure arrangements (1) Utilizing international application systems (such as PCT): Companies can first submit preliminary applications in their own country or strategic markets, and then choose to enter other countries within the prescribed priority period (usually 12 months). In this way, the application time can be flexibly arranged according to the requirements of each country for disclosure time, and the disclosure in some countries can be delayed until the product is launched on the market. (2) Submitting applications in different countries: Some countries disclose the application 18 months after submission, while other countries may have different disclosure requirements. Companies can choose to delay the disclosure of application content in certain key markets based on the characteristics of each country's system to keep the technology secret until the commercialization advantage is converted into market share. 2. Differentiating priorities and application order Using priority strategies, apply for more important or sensitive technical content in the home country first, and then use the priority period to supplement the application in other countries. This not only ensures the early locking of core technologies, but also adjusts the time of subsequent applications according to foreign disclosure policies, effectively extending the "first-mover period" in the global market. 3. Utilizing systems such as "patent continuation" (or divisional application) In some countries, applicants can submit divisional or continued applications based on the original application, thereby extending the effective period of the patent right (within the scope permitted by law). This can not only continuously broaden the scope of protection, but also use the differences in review time limits or disclosure time points to adjust the rhythm of technology disclosure to match the product life cycle and extend the market exclusivity period. 4. Balanced strategy between confidentiality and disclosure In some countries, the requirements for disclosure details are relatively low during the patent approval process. Enterprises can choose to apply first in such countries and take advantage of the "secret application"; while in countries that force early disclosure, they can control the application content and selectively disclose key technical details. By selectively managing the disclosure time of technical information on a global scale, some competitive advantages can be retained before the product is launched. 5. Patent layout synchronized with product launch plan When conducting patent strategic planning, enterprises should combine the product's R&D, testing, approval and launch schedule to determine the time of patent applications in different markets. By laying out core markets in advance, entering other countries later, and taking advantage of institutional differences among countries, we can ensure that most key technologies are still under application or review when the product is launched, thereby legally delaying the possibility of competitors copying. 6. Risk Prevention and Compliance Considerations Although this strategy of taking advantage of institutional differences can extend the exclusivity period after the product is launched, it is important to pay attention to: • Ensure that all applications comply with the laws and substantive requirements of each country and avoid patent invalidation or disputes due to deliberate concealment. • Pay attention to the supervision of "patent abuse" or "evergreening" (patent extension) in various countries to avoid unfair competition or antitrust issues. • Maintain close coordination with product development and marketing to prevent technological innovation and competitive advantages from being affected by adjustments to patent strategies. In short, through in-depth research on patent application and disclosure systems in different countries and designing flexible application strategies (such as reasonable use of international application steps, divisional applications, and clever use of priority rights), the disclosure of core technology information can be effectively delayed before and after the product is launched, and the patent protection period can be appropriately extended, thereby extending the product's time to market and competitive advantage in the global market. But at the same time, this strategy requires companies to have a detailed understanding of the laws of various countries and to work closely with professional patent agents or legal advisors to ensure that the implementation process achieves both commercial goals and does not violate relevant legal provisions.
