近年來，隨著世界各國對於ESG永續經營的重視及努力，使得占全球碳排放量高的建築產業被迫採用新技術轉型，其中，使用資源循環綠色建材，以降低碳排放、減少天然資源開採及減少廢棄物產生的環境污染等等，已被投資人及國際企業更加重視。
本研究以「綠色建材」作為技術主題，透過GPSS全球專利檢索系統搜集相關數據，進行美國、歐洲以及台灣專利資料庫之相關專利整體趨勢分析，從中得出三局歷年專利申請件數趨勢、主要專利權人以及IPC分類號趨勢之分析，並進一步針對三局資料庫中的綠色建材專利進行被引證數分析，透過揭示三局中被引證次數較高的專利、引用該些重要專利的廠商，以更全面地了解綠色建材領域的重要專利。最後，利用社會網絡分析工具Pajek，以得出三局相關專利的代表性發展脈絡，探討美、歐、台綠色建材之發展方向，並提供一些觀察供綠色建材領域的研究開發者及專利管理者參考。
本研究分析結果可得以下結論：
1.綜觀三局之發展趨勢，綠色建材技術之發展已趨於成熟。
2.根據主要申請人分析，美國SOLIDIA建材公司積極佈局於三局專利申請；此外，台灣學研機構相當重視綠色建材技術之發展，並且擁有獨自研發的能力。
3.根據IPC分類號趨勢之分析，推估未來除了綠色混凝土與環保牆體或屋頂外，結構構建之相關專利亦可能成為綠色建材之發展重點之一。
4.根據主路徑分析，歐洲和美國在綠色建材產業中採取了類似的技術路徑，都著重於減少建築材料中的二氧化碳排放，其中一個共同點是探索利用碳捕捉技術來捕捉二氧化碳並將其封存在建築材料中。

The study focuses on green building materials as the technological theme, and collects relevant data from the GPSS global patent retrieval system to conduct an overall trend analysis of patent databases in the United States, Europe, and Taiwan. The analysis includes three aspects: the trend of patent applications over the years, major patent holders, and the trend of IPC classification numbers. Furthermore, this study conducts a citation analysis of green building material patents in the three databases, revealing the most highly cited patents and companies that reference those patents to gain a comprehensive understanding of important patents in the field of green building materials. Finally, using the social network analysis tool Pajek, this study provides representative development contexts for the relevant patents in the three databases and explores the development directions of green building materials in the United States, Europe, and Taiwan to offer some insights for researchers and patent managers in the field of green building materials.
The conclusions drawn from this study are as follows: (1) The development of green building material technology has become more mature based on the trend analysis of the three databases. (2) According to the analysis of major applicants, the U.S. company SOLIDIA Building Materials has actively applied for patents in the three databases. In addition, research institutions in Taiwan attach great importance to the development of green building material technology and have the ability to independently research and develop such materials. (3) Based on the trend analysis of IPC classification numbers, it is estimated that in addition to green concrete and environmentally friendly wall or roof materials, patents related to structural construction may also become one of the focuses of green building material development in the future. (4) Based on the main path analysis, Europe and the United States have taken similar technological paths in the green building materials industry, both focusing on reducing carbon dioxide emissions in building materials. One common point is exploring the use of carbon capture technology to capture carbon dioxide and sequester it in building materials.
