According to the citation data of the patent,patent citations fluctuate over time.The fluctuation of the citations of some patents always stays within a relatively stable range after being authorized.Which is called‘stationary patents’.Some patents,after being authorized,have many fluctuations in the number of citations of patents,such as rapid increase or rapid decline over time,which are called‘non-stationary patents’.To directly reflect the fluctuation of the citation quantity of patent,the RSD value is used to quantitatively describe the degree of patent citation fluctuation.The calculation procedure of the RSD value is described in detail with the patent‘5675627’as an example,shown in Table 1.
