Objective: The purpose of this study is to investigate the applicability of maps obtained from the co-word analysis of patents for medical and laboratory equipment using the opinions of experts in this field.Methodology: This research has been done in two stages. In the first stage, all-word analysis technique was used to extract concepts and draw thematic maps based on rank centrality, intermediate and proximity indicators. Then, in the second stage, using the Delphi technique, the opinions of a group of experts in the field of medical and laboratory equipment were used to evaluate the applicability of the maps and analyzes extracted in the first stage. The statistical population of the present study in the first stage is all the patents in the field of medical and laboratory equipment that have been registered in the database of the US Patent and Trademark Office in the period 1984 to 2014. In the second phase of this research, to implement the Delphi method, a panel consisting of a group of specialists in the field of medical and laboratory equipment who had a history of service and activity in this field, was formed.Results: Thematic maps could be useful in providing an overview of the content of patents in the field of medical and laboratory equipment. If scientific plans in the field of medical and laboratory equipment become a road map, they can have a positive impact on the decisions of experts in this field. Also, by eliminating the shortcomings in the scientific plans of medical and laboratory equipment, it is possible to improve the existing technologies in this field. Therefore, drawn scientific maps can be a good tool for those who want to gain a basic understanding of patents in the field of medical and laboratory equipment.Conclusion: The maps obtained from the co-word analysis of patents in the field of medical and laboratory equipment have been able to be effective in understanding the content of this scientific field.

Purpose: Adoption and diffusion of innovation is one of the indicators of community progress. Innovation is a process in which ideas and new methods are created or developed. The aim of this study was to visualize the scientific structure of innovation diffusion during 1990 – 2011. Method: The research method was scientometrics. During the period of 1990-2011, 3180 records were extracted in WoS and necessary analyses were performed on them. Findings: Results showed that the collaboration coefficient from 0.204 in 1990 raised to 0.508 in 2011 and the average of collaboration coefficient was 0.378 for the whole period. Due to the critical value at confidence level of 95% (0.0177> 0.8578), it can be said that the present work is in accordance with Lutka’s law. The fields of Management with 796 records (25%), Commerce with 546 records (17.2%), and Economy with 428 records (13.5%), ranked first to third respectively in order to diffusion of innovation research publishing. among 81 countries that have produced documents related to the diffusion of innovation, findings showed that over 57 percent were produced in the US and England. Iran with a production of 7 records (% 2.0) in this field ranked 34th. Results: The present study revealed significant correlation existing between cumulative annual frequency of scientific outputs, and year of study. An exponential regression was applied to model the high correlation between cumulative number of documents and the year of study. Using the regression equation, it can be estimated that in 2015, the number of scientific publications on this topic will be twice of the number of publications in 2006. Finally, by the scientific mapping of innovation diffusion on a global basis (GCS), eight clusters were identified and introduced.
