A Study on the effect of patent system on Japanese, US and European firms' patenting behaviour

(1)首先对前人研究中存在的问题进行了分析。我们构建了专利战略的管理和经济分析框架。(2)在研究期间，我们进行了原始调查。我们完成了调查问卷的收集。我们正在写一篇关于调查结果的论文。(3)从3个知名专利数据库中提取分析所需的数据项和目标专利数据供研究人员使用。此外，我们计划构建这些数据库。(4)为了获得我们分析的专利数据，我们开发了一个程序，可以自动从每个国家的专利电子图书馆下载数据。我们使用该程序来下载数据并检查我们给定的研究问题。

(1)Firstly, we examine some problems in a previous research. We built the analysis framework for management and economics of the patent strategy. (2) During a research period, we carry out original survey. We finish collecting questionaire for our survey. We are writing a paper on the result of our survey. (3) We extract the necessary data item for analysis and a target patent data from three well-known patent databases for researchers. Moreover we plan to construct those databases. (4) In order to obtain patent data for our analysis, we develop a program to download data from each country patent electronic library automatically. We use the program to the download of data and examine our given research question.
