本文摘要

本研究以3D電腦繪圖技術的相關專利資訊作為統計分析的目標,解讀有關這個領域的發展與現況。從專利件數、國家數及專利權人數的成長可以發現這個領域目前處於技術成熟期。其次,美國及日本是這個領域的重要國家,不僅是技術發展的先驅,而且專利大多掌握在發源於這兩個國家的大型國際公司。發明人分析也發現主要發明人大多都任職在這些企業。此外,團隊共同研發是研發過程的主流。最後,本研究並區分出具有競爭力的技術分類。

Using the patents related to the 3D computer graphics as the target of statistical analysis, this Paper presents a study for the current situation and development of the technical field. From the growth of all the statistically counting numbers from the patent, including applying patents, assignees that possessed the patents, and countries to which the assignees were belonged, this field was possibly going toward its stage of technological mature. Moreover, we can find that the United States and Japan are the two countries dominating the field and those are also the pioneers in the technical development. The patents are usually possessed by gigantic companies, which originally came from the United States and Japan but nowadays had a global distribution. The analytical result demonstrates that most of the key inventors were working for these gigantic companies. Furthermore, collaboration by teamwork has been the mainstream of working models in the process of technical development in the field. Finally, in this study we also identified several competitive technology items in the field from the patents.
