The invention provides a cloud computing patentability technology navigation system and method. The cloud computing patentability technology navigation system comprises a cloud computing patentability technology navigation server, a data importing tool, a data cleaning tool, a word frequency analysis tool, a semantic analysis tool, a patent analysis tool, a literature analysis tool, an analysis result processing tool, a cloud computing patentability technology data mining tool and a report output module. The method comprises the steps that the imported data are screened and cleaned; word frequency analysis and semantic analysis are conducted on the data; after patent data and the literature data are analyzed, a patent analysis report and a literature analysis report are output; the technical data range, in which patents can not be applied any more, formed by an applied patent and a disclosed technology is obtained; merge application is conducted with IPC data, and cloud computing patentability technological data are mined; a cloud computing patentability technology navigation report is output. According to the cloud computing patentability technology, an intelligent system is used for replacing manual work, operation is simple and convenient, time and resources are saved, the processing efficiency is improved, and a statistic analysis result is more accurate.
