| Summary: | 碩士 === 國立臺灣科技大學 === 專利研究所 === 106 === Patentees, Entities, and even countries, everyone wants to know how much a patent or a group of patents is worth. People have been using accounting method to evaluate patent value, patent analysis to assess comprehensive value, and even patent indicators of the bibliometric method to evaluate. This research focus on patents about mid-drive electric bike. By letting the experts to evaluate the value of a patent and comparing them to the value determine by the patent forward citation indicators, we try to understand the appropriateness of using the forward citations as a patent indicator.
The research cooperates with the senior engineer from the R&D department of the Cycling & Health Tech Industry R&D Center. After letting the expert manual read and judged the patent value of the US patent related to mid-drive electric bike, distribute the patents into three groups: low value, middle value, and high value. Then, analyze the outcome of patent value groups with the historical patent applications and patent forward citations.
The historical patent applications and patent forward citation analysis are used to understand the developing trend of the subject over the years and the overview of the forward citation; the distribution of patent value groups rated by the expert, forward citation trend analysis, and individual analysis of each patent value groups are used to determine the difference and relationship between patent value rated by the expert and forward citation. At last, the additional discussion of patents having 0 forward citations are used to understand the performance of the patents which are unable to be determine by the forward citation indicator.
The result are organized and listed as follows: (1) The mid-drive electric bike industry is growing drastically in recent years, the analysis subject is a new technology; (2) The higher the patent value rated by the expert is, the more the average forward citations; (3) From the perspective of the expert rating result, the earlier patents have higher proportion being low value, and the more recent ones are more likely to be middle value or high value; (4) Because of the accumulation of time, chronologically, patents in the mid-term have higher forward citations than the others, but are rated more to be low and middle value; (5) In the technical field of the research, with the baseline of the expert rating, using forward citation to determine the patent value has a higher probability of misjudge; (6) Patents having 0 forward citation are possible to be rated all low, middle, or high value, as a result, patent forward citation indicator should still rely on the expert’s judgement.
