Technological convergence provides an important foundation for the development of scientific and technological innovation. In this paper, Apriori algorithm is used to analyze the cross-domain technology integration situation of US Utility patents (USP) across four or more International Patent Classification (IPC) sections through association rules. According to calculations, the frequency of occurrence of sections B, G, H, and C of the IPC of the USP is greater than 20 000 times, which is the field where technology convergence occurs frequently; Support of association rule for class G06 to H04 is 0.066, reflecting the convergence trend of artificial intelligence and communication technology. Support of the subclasses C07K and A61K is 0.016, and support of C12Q and G01N reaches 0.027, revealing the interdisciplinary direction of materials testing techniques, biology and medicine. Through the association rules, the track of technology integration of the United States is excavated, and the situation of technology convergence development is revealed, which provides references for technology innovation, as well as construction of interdisciplinary disciplines in universities.
