Technical inventions of companies or private inventors require a patent application in order to utilize the protected invention economically over a specific time period and to exclude third parties. This thesis depicts the problems in the procedure of a patent application from the viewpoint of an authorized applicant as well as the potential of an applied property right. For this purpose, potential difficulties, of both material and formal character, were compiled on the basis of the national patent application procedure. Subsequently, positive effects of a patent application and international patent application possibilities were taken into account. The composition of a patent application often causes various problems, since many patent applicants lack the knowledge of the required terminology for a claim. The prejudice to innovation of previous published and unpublished patent applications and patents complicates and sometimes prevents a successful application, primarily at substantive level. Previous research and consultation of public, private organized contact points or of a patent attorney raise the chance of successful grant of patents of the applied inventions by the authority. Successful applications depend on the grant of a patent, the market situation and the respective invention. In conclusion, it can be assumed that many patent applicants underestimate the personal effort, such as the preparation of the application and the investigations previous to the actual submission at the patent office.
