This study explores the intersection of digitalization and legislative support in intellectual property protection for fodder additive production technologies, highlighting its role in driving agricultural innovation and sustainability. The literature reveals a dynamic interplay between advancements in patent law, smart technologies, and digital tools within the agricultural sector. Patent law emerges as a critical driver, with global complexities in securing patent protection posing challenges for inventors, particularly in the context of fodder additive technologies. These legal frameworks significantly influence innovation trajectories and market accessibility. Smart technologies, discussed within the framework of sustainable agriculture and the 4th Industrial Revolution, demonstrate the potential to enhance productivity while addressing ecological, economic, and social dimensions. However, concerns over market concentration and inequitable technology distribution underscore the need for inclusive legislative measures to ensure fair competition and accessibility for small producers. Case studies from Australia, Japan, and the European Union further contextualize these themes. The fragmented policy landscape in Australia highlights the need for cohesive digital governance frameworks, while Japanese studies emphasize the role of community networks in technology adoption. EU research showcases the transformative potential of digital tools in optimizing resource use, enhancing sustainability, and improving agricultural efficiency. The findings underscore the necessity of robust legislative frameworks to balance proprietary innovation and public accessibility. This study concludes that integrating digital tools with supportive policies can drive innovation, enhance sustainability, and ensure equitable benefits in agricultural technology development, paving the way for resilient and sustainable food systems.
