本研究は2025年までのOrbit Intelligenceデータを用いて、中国を中心に農業気候関連特許ファミリーのライフサイクルを分析。適応志向の製品ベース技術が優勢で、デジタルやサービス志向のソリューションは限定的。中国では2010年代半ばに特許出願が急増したが、その後大部分が失効し、大学保有特許の被引用数が低いことを実証。特許数のカウントからライフサイクルへの視点転換を促す。
English
Using Orbit Intelligence data until 2025, this study analyzes the lifecycle of agricultural climate-related patent families, focusing on China. It finds a predominance of adaptation-oriented product-based technologies (soil management, irrigation) and a compressed innovation cycle in China: a sharp expansion in the mid-2010s followed by high attrition. Nearly two-thirds of patent families are inactive, and inactive patents receive fewer forward citations, especially university-owned ones.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
中国の農業気候技術特許のライフサイクル分析は、日本の農業分野でのグリーン特許戦略や資源配分の参考になる。特に大学保有特許の低い被引用数は、産学連携や技術移転の課題を示唆し、日本の農林水産省や関連政策に示唆を与える。
In the global GX context
This paper provides empirical evidence on the lifecycle of green patents in China's agricultural sector, highlighting the high attrition rate and limited technological impact of university-owned patents. For global GX, it underscores the need to move beyond patent counts to lifecycle metrics when evaluating innovation systems, relevant for countries designing climate-smart agriculture policies.
👥 読者別の含意
🔬研究者:Researchers studying green innovation metrics should note the use of patent lifecycle analysis and the finding that inactive patents have lower forward citations.
🏢実務担当者:Corporate sustainability teams in agriculture can gain insights into the patent landscape and the importance of commercialization versus filing.
🏛政策担当者:Policymakers in agricultural climate policy should consider the low impact of university patents and the need for mechanisms to bridge innovation to practice.
📄 Abstract（原文）
Agriculture is both a major source of greenhouse gas emissions and highly vulnerable to climate change. While green patents are widely used to track sustainability-oriented innovation, limited research examines how agricultural climate technologies evolve across their full patent lifecycle. This study analyzes agricultural climate-related patent families using Orbit Intelligence data until 2025. Although global patterns are mapped for context, the empirical focus centers on China, which dominates worldwide filings. Using CPC and IPC classifications to identify adaptation and mitigation technologies, we examine temporal dynamics, technological composition, institutional ownership, collaboration networks, legal status, and forward citation outcomes. Results show a strong predominance of adaptation-oriented, product-based technologies, particularly in soil management and irrigation, with limited representation of digital or service-oriented solutions. Within China, patenting exhibits a compressed innovation cycle: a sharp expansion in the mid-2010s followed by substantial attrition. Nearly two-thirds of patent families are inactive. Econometric evidence indicates that inactive patents receive significantly fewer forward citations, especially those owned by universities, suggesting weaker technological visibility and limited integration into cumulative innovation trajectories. By shifting attention from patent counts to patent lifecycles, this study highlights structural features of state-driven innovation systems and provides a foundation for future research on commercialization, institutional design and climate-oriented agricultural policy.
