利用專利分析技術探討區塊鏈發展趨勢

本研究以專利分析方法，探討區塊鏈(Blockchain)技術之研發現況，所針對之指標包括專利數目比較分析、技術生命週期分析、引證數分析及專利分類號分析等，其內容涵蓋國家、企業與技術層面，並以美國專利商標局專利資料庫執行區塊鏈(Blockchain)檢索。在國家層面專利產出分析方面，美國表現最為優異，在廠商層次的表現則以IBM公司取得最多專利件數為最佳，而技術層次主要著重在IPC技術領域G06Q/H04L/G06F運用。研究結果可提供後續研究者、台灣企業及政府對區塊鏈研究、研發創新與政策擬定的參考。

This research explores the research situation of blockchain technology by patent analysis method. The indicators targeted include comparative analysis of patent number, technology life cycle analysis, citation number analysis and patent classification number analysis. The content covers countries、enterprise and the technical level, and use the US Patent and Trademark Office patent database to perform blockchain search. In the analysis of patent output at the national level, the United States performed the best. At the manufacturer level, the number of patents obtained by IBM was the best. While the technical level mainly focused on IPC technology field G06Q/H04L/G06F. The research results can provide reference for follow-up researchers, Taiwanese companies and governments on Blockchain research, R&D innovation and policy formulation.
