美国助理国防部长办公室资助,兰德国防研究所采办和技术政策中心完成了一份报告,作者是兰德公司的高级助理C.Eusebi和R.Silberglitt。在此研究报告之前,已经有许多研究人员做过基于专利引用或者文献引用开展技术预测的研究,但是最近的一项研究表明,专利的引用与其价值之间的函数关系并非线性,并且二者之间的单调性也没有以前认为的那么理想,这说明上述方法在预测新技术时存在着一定的不足。美国专利商标局(USPTO)的专利分类系统已被用于 Aided by the U.S. Assistant Secretary of Defense Office, a report was completed by the Institute for Acquisition and Technology Policy at the Rand National Defense Institute, led by C. Eusebi and R. Silberglitt, senior RAND assistants. Prior to this study, many researchers had done research on technology predictions based on citing citations or citations, but a recent study shows that the functional relationship between a patent's citations and its value is not linear and that both Monotonous between the nor previously thought so ideal, indicating that the above methods in the forecast of new technologies there are some deficiencies. The U.S. Patent and Trademark Office (USPTO) patent classification system has been used
