This study focused on the classifications assigned to patents and examined the "interdisciplinarity" from the following two perspectives: (1) expected values for growth in the number of citing fields, when regarding the observation period as being in a synchronic state and assuming that the strength of connections between each patent and citing fields is constant; and (2) empirical values for growth in the number of citing fields according to the increase in the cumulative number of citations over time. From the results, it was confirmed that the strength of potential connections between each patent and citing fields changes over time. Especially in the fields of "chemistry; metallurgy" and "physics," the following change is considerable: a patent tends to receive citations repeatedly from a limited range of fields for a while, but later comes to be cited by various fields.

这项研究的重点是分配给专利的分类，并从以下两个角度检查了“跨学科性”：（1）引用领域数量增长的预期值，当关于观察期的同步状态并假设每个人之间的连接和引用领域之间的强度是恒定的； （2）根据引用累积数量随时间的增加，引用字段数量增长的经验值。从结果中可以证实，每种专利与引用领域之间的潜在连接的强度会随着时间而变化。尤其是在“化学；冶金”和“物理学”的领域，以下变化很大：专利倾向于在有限范围内反复接受一段时间的引用，但后来被各种领域引用。
