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.

Aims: The purpose of these research was examine the knowledge flow between Islamic countries inventors in order to determine the impact of lag time in patents knowledge flow.Methodology: Citation analysis was used as the research method, the research population includes all patents of Islamic countries recorded from 2005 to 2014 in the USPTO. Using the especial formulas lag time was calculated.Finding: research Finding showed that in more than 95% of Patent, the length of time between the patent application and the granting of the patent takes 2-3 years. Average of lag time between examined patent citations were 2.93 years. Data analysis also showed that maximum lag time frequency were 2-3 years that which includes more than 40% of cited patent.Results: the results of testing hypotheses showed that there are significance correlation between grant year, lag time between of grant year and grant year of cited patent with knowledge flow in p<0,05 level. Results also showed that the relationship between variables are negative. The findings from multiple regression analysis revealed that about 13% of log time’s variable variance was determined by knowledge flow.
