This study estimated the economic effectiveness of 26 representative patents out of the highest-evaluated(S-level) NIFS-owned patents in the five fields ''Aquaculture'', ''Aquatic disease'', ''Biotechnology'', ''Safety & processing'' and ''Fisheries engineering''. In addition, I suggested a plan for utilizing the government-owned patents in fisheries area by comparing characteristics of each research field.
Patents in aquaculture field showed a higher R&D period, budget, market size and share compared to other fields. Also, since the term of benefit is long, the economic effect according to NPV was high. In the fields of fisheries engineering and fisheries disease, patents have a large effects in terms of IRR and BCR because the R&D period is short and R&D budget is lower than other fields, but the effect is large. In common with the other patents, the results of IRR and BCR analysis of aquaculture patents showed the patents with a short research period and small budget and high market share are economically feasible. While patents in the field of biotechnology showed conflicting results in economic feasibility analysis of pharmaceutical substances for human and for fish depending on the market in which the technology was applied, the economic feasibility of pharmaceutical patents for human body was high. In the field of safety & processing, a sufficient demand market has been formed, but the result of economic feasibility analysis was low because the R&D contribution rate and continuous investment are lower than the other four fields.
The technology commercialization of government-owned patents is difficult to obtain immediate R&D investment effects due to the characteristics of fundamental researches. Even though the economic feasibility is lower than that of thers, it is necessary to continue to secure and utilize the source technology at the national level, taking into account the economic impact that national R&D has on the entire industry from a long-term perspective.
