In our materiality assessment, we have expressed our commitment to creating shared value (CSV) through our core business to address shared challenges in society. We aspire to create value for both society and the company through innovation, supported by a robust approach to intellectual property (IP) management led by our IP Department. Guided by its medium-term plan, the department oversees all IP-related initiatives, ensuring our intangible assets are strategically developed and utilized in alignment with the company's broader business goals and medium-term strategies. It engages in company-wide collaboration to create intellectual assets that grow our current business while working to put strategies and plans into action to enhance IP governance.
As we make and sell our products, we strive to improve them to deliver more advanced solutions. This is our focus for both business and IP. Such efforts have boosted patent applications associated with our solutions, raising the three-year average through FY 2024 to more than two times that of FY 2014.
We are also eager to produce IP for the future as part of our strategic investment in seeking long-term growth. In our nonlinear, trial-and-error process to innovate for new technologies and businesses in untapped domains/markets, we are using IP landscapes* increasingly to strategize how we create intellectual assets for competitive differentiation and strengthen our IP portfolio both in and outside Japan. We are also gathering and analyzing business intelligence in the IP context to support decision-making when it comes to selecting new businesses or partners for innovative tagging.
With an emphasis on protecting and leveraging the creative outputs we produce from solving customer pain points, we have been working to increase our patent utilization rate. Also, we regularly review and update our patent portfolio, replacing older or less valuable patents with newer, more valuable ones. This helps keep our portfolio focused, aligned with our business goals, and supportive of both profitable growth and better capital efficiency. As a result, our patent utilization rate continues to rise, mirroring the industry trend.
While we seek stronger patent protection to reinforce our global growth, the number of patents we hold in key countries outside Japan has grown rapidly such that by the end of FY 2024, it is already more than 2.5 times that of FY 2014. This corresponds with the bigger role our overseas business now plays at the group level. It brought in almost 50 percent of our consolidated sales in FY 2024, up from just around 30 percent in FY 2014.
