当前,苏联、美国、西德、日本、加拿大等国家都建立了国家专利机构为中心的全国专利文献服务网。据有关资料统计,苏联直接、间接从事专利文献工作的有150万人,收藏专利文献4.8亿件(包括复制品)。美国专利局设有庞大的专利文献库及阅览室,各地还有38个图书馆收藏整套专利文献,每天复制专利文献约25000件。日本专利文献服务工作,在各地设有45个分部,124个地方阅览室。西德有13个地方专利文献服务中心。加拿大免费向重点企业提供专利检索报告。那么工业发达国家为什么这样重视专利文献的利用呢,就是因为专利文献对促进技术腾飞和经济发展有着巨大作用。众所周知,专利文献(指专利说明书)不仅以清楚而准确的语言详细描述了发明的主要内容,而且还带有附图,这就使该专业的技术人员能够实施。因而对科研功关、科研选题、
At present, the Soviet Union, the United States, West Germany, Japan, Canada and other countries have established national patent agencies as the center of the national patent documentation service network. According to the statistics, there are 1.5 million Soviet-Chinese directly and indirectly engaged in patent literature and a collection of 480 million patent documents (including copies). The United States Patent Office has a large library of patent documents and reading rooms. There are 38 libraries around the country collecting the entire set of patent documents and copying about 25,000 patent documents daily. Japan patent literature services, with 45 branches throughout the 124 local reading room. West Germany has 13 local patent documentation service centers. Canada to key enterprises to provide free patent search report. So why the industrialized countries so much emphasis on the use of patent documents, it is because the patent literature to promote technological take-off and economic development has a huge role. It is well-known that patent documents (referring to patent specifications) not only describe the main contents of the invention in detail in a clear and precise language, but also with accompanying drawings, which will enable those skilled in the art to carry out the same. Therefore, scientific research, research topics,
