However, the researches in our nation only emphasize on the influence of the number of patents in domestic industries on economic utility and company value. In foreign countries, there are only some researches about the influences of the patents from different areas on economic utility. The protection of patent is limited to regionalism and the mechanism of payment, so the study focuses on the patents from different areas to explore the level of economic utility. The purpose of the study is to help companies find some area to apply for patents which could produce the highest utility, and this way corresponds to the cost utility. The boundary of the study contains the United States, Japan, and Europe, which are the authorities of the field of patent. The study retrieves the number of patents that the companies have gained and then explores the economic utility. The participants are taken from the top 1000 global manufacturers in Industry Week in America. There are 749 companies which belong to the United States, Japan, and Europe, so the study collects the information about patent and finance related to those companies. The research model is built by knowledge production function to study the influence of the patents from different areas on economic utility. The study uses fixed effect model to estimate the panel data, and it discovers that: Firstly. All the companies which have patents in the United States and Europe have positive significant economic utility. Secondly, the economic utility gained from the patents in Europe is significantly higher than those in the United States and Japan. Thirdly, the economic utility measured by sales revenue in American and Japanese company which gained patents in their own countries has positive significant effect, except for Europe, but the measures of price-to-book ratio and Tobin’s Q that are indicators of intangible assets significantly have results. Fourthly, in the point of American and European companies’ patents gained from different areas, the patents gained from Europe could produce significantly higher economic utility than those in the United States and Japan. Key word: patent, number of patents, patent right, Tobin’s Q USPTO EPO and JPO.
