خلاصة:
The aim of this study was to investigate the term Nano in subject categories of patents and to analyze the conceptual relationship between them. The method of this study is based on the study of mathematical models of the disease outbreaks. Population composed of published patents which used the words of “Nano" or "Nanotechnology” in the title or abstract. The patents retrieved from the Institute of Patent and Trademark of United States of America (USPTO). The findings showed that the patents trend had an exponential relationship and an incremental growth. So that the absolute number of patents has increased from 2 in 1995 to 1474 patents in 2013. The cumulative growth of subclasses has been involved in Nano subject over time that has an S state logistics, which is reached from 2 in 1995 to 3032 in 2014. The results showed that the USPTO patents at this time confirm the theory of Goffman (1971) that transmits of an idea as the dissemination of influenza are reversible.

/ Studying the Application of Epidemic Theory in Transmission Cycle of Technology: A Case Study of Nanotechnology Patent Faramarz Soheili Department of Knowledge and Information Sciences, Payame Noor University, Kermanshah-Iran Corresponding author: F soheili Apnu.
To solve it can be to study the epidemic of this technology in subject classes of the patent issue, and considering their relationship with each other in the process of emergence and development of the technology were mentioned.
In the present study, considering to identify relevant topics and involved in the nanotechnology field which is resulted in the identification of related industrial areas and introducing them for developing and improving technology in this field.
Also, the findings can help more policy maker's insight in the field of nanotechnology, the development of a technology and the role of studies based on the subject co-occurrence can help understand better the epidemic of a technology.
A growth graph of prone to contagion subcategories in nanotechnology area at patents in the USPTO system In Figure 3, indicating the process of increasing and decreasing the frequency of categories involved in the Nano issue, the model SIS of an epidemic of infectious diseases.
In studying the third question of compliance models based on epidemic models was identified with patents that are confirmed the increased and decreased frequency of categories involved with the subject of nanotechnology and with the spread of infectious diseases to SIS (figure 3).
