This document discusses patents and making money from ideas. It provides tips for writing a patent, such as making the body extensive with many future possibilities but not too abstract. Claims should break down the body into long and wide but focused sections. Registering a patent can cost $30K-$50K and take 3-5 years for approval. As an alternative, a provisional patent can be registered for about $100 to delay the full patent process for a year. Public knowledge cannot be patented.
