However, along with the accumulation of the applications of patents a company has made, comes the enormous amount of expense of the maintenance fee of the rights. As a result, evaluate patents’ value and determine whether a company should keep holding on to them has become a complicated problem and a research topic scholars have been working on. Some of the scholars had proved with substantial evidences in the previous literatures that the value of a patent has positive correlation with the number of patent forward citations. However, there are scholars indicating otherwise with database analysis and doubt the results. The research reviewed the related previous literature and define the scope of the subject with the R&D senior executive of the partner cooperation. After searching for the patent pool aimed to determine, the R&D senior executive will then asked to subjectively judge the value of the patent. At last, the research will investigate the credibility of the determination that the value of the patent correlates with the number of patent forward citations. The result of the research are listed as below: 1. Under the integrate data analysis of the research, the group of patents that are valued higher by the expert does not necessarily have higher number of patent forward citations; 2. In this research, the forward citation analysis of forward citation number with or under 99, the group of patents having higher value, determined by the expert, have a higher forward citations in average; 3. Within the scope of the subject’s technical field in this research, based on the judgement of the expert, although using the forward citations of patents as index of patent value has some certain extent of referencing, there is still a high probability of misjudge; 4. In the research, patents having 0 forward citation still has the chance to be determined as middle or high value. As a result, expert’s consultant is still required to correctly determine the value of a patent.
