This technical book is designed to help you prepare patent or utility model applications on your own. It explains the required components of an application and provides suggested wording. Numerous practical examples offer additional guidance. The structure of the book follows the recommended process for drafting an application. First, it describes how to present the state of the art in the application. The state of the art represents the starting point for the creation of the invention. By examining the state of the art, the inventor identifies shortcomings that lead to the invention. These shortcomings define the objective of the invention. This development process of the invention must be reflected in the application. The next step in drafting the application is a description of the various embodiments of the invention. Finally, the claims are formulated. This sequence has the advantage that the most challenging step—drafting the claims—comes last. By this point, the inventor has a thorough understanding of the different aspects of the invention, which makes writing the claims significantly easier.
