基于专利导航的东北林蛙产业技术创新现状及优化对策分析OA

The wood frog(Rana dybowskii)industry has developed a well-structured and integrated industrial chain encompassing breeding,processing,and sales.This study utilizes patent navigation analysis based on 889 global patents filed over the past decade to assess technological innovation trends and challenges within the wood frog industry.The findings indicate a significant imbalance in the industrial chain,where downstream product development has been prioritized over upstream fundamental research.Specifically,more than 70%of the patents(625 in total)are concentrated in the areas of health products and cosmetics,particularly focusing on extraction techniques for Oviductus Ranae(57 patents)and peptide preparation methods.In contrast,upstream sectors such as germplasm breeding remain severely underrepresented,accounting for less than 2%of all patents(18 in total).Persistent technological deficiencies include an overemphasis on facility improvements in breeding practices(127 patents),as well as repetitive and low-innovation processing methodologies,despite achieving economies of scale.Terminal markets demonstrate substantial investment in cosmetic R&D,with 44%of product patents related to this domain.However,critical gaps persist in large-scale,standardized artificial breeding technologies,as evidenced by only two patents in this area over the past two decades.Technological traceability analysis identifies three systemic issues:limited collaboration between industry,academia,and research institutions;insufficient technological barriers to entry;and inefficiencies in translating scientific research into commercial applications.These factors collectively contribute to the industry's reliance on short-term applications at the expense of foundational innovation.To address these bottlenecks,this study proposes a comprehensive strategy:1)Establishing a conservation and expansion system for the original breeding base of northeast forest frogs to enhance genetic resource sustainability;2)Prioritizing core technologies in fully artificial breeding and deep processing of wood frog-derived products to overcome scalability and innovation limitations;3)Strengthening intellectual property protection mechanisms to incentivize R&D activities;4)Promoting interdisciplinary collaboration to improve the transformation of research achievements into practical applications.Collectively,these measures aim to rebalance the industrial chain,bridge technological disparities,and ensure long-term competitiveness.The findings emphasize the urgency of redirecting innovation efforts toward upstream research while strategically optimizing the downstream patent landscape,offering a systematic roadmap to resolve structural constraints within the wood frog industry.
