一专利文献是科技文献中最有价值的一种文献资料,近期的研究结果表明,世界上一般的发明都可以从专利文献中查到。近期的研究结果还表明,全世界每年约3099件发明专利中,有90％以上的发明刊登在专利文献上。与其他科技文献相比,专利文献能较早地提供更直接、更详细完整的说明资料,包括对现有技术水平,以及目前存在的问题和解决的办法的说明。在制订科技规划时,特别是在制订地区或行业的中短期科技计划时,通过检索,可进行国内外市场的战略调查,了解国内外的研究方向、研究重点以及技术市场经济动向。如哪些国家在哪些研究领域里完成了某项发明创造,哪些公司、企业或单位到哪几个国家去申请某项专利,哪些国家或地区需要什么技术或产品等等。掌握了国内外的技术市场动向,就可以根据本行业的资源优势、技术优势来确定重点研究方向,使制订的科技计划建立在
A patent document is one of the most valuable literature in scientific literature. Recent research shows that the most common inventions in the world can be found in the patent literature. Recent findings also show that more than 90% of the approximately 3,099 invention patents worldwide are published in the patent literature each year. Compared with other scientific and technical documents, the patent documents can provide earlier and more direct, more detailed and complete description of the information, including the state of the art, as well as the current problems and solutions to explain. During the formulation of science and technology plans, especially in the formulation of short- and medium-term science and technology plans in regions or industries, we can carry out strategic investigations in domestic and overseas markets and find out research directions at home and abroad, research priorities and trends in technology market economy. Such as which countries in which research areas have completed an invention, which companies, companies or units to which countries to apply for a patent, what countries or regions need technology or products, and so on. Grasping the trend of technology market both at home and abroad, we can determine the key research directions according to the resource advantages and technical advantages of the industry so that the scientific and technological plans formulated can be based on
