Inventions are objects, techniques or processes that offer elements of novelty. Some inventions can be 100% original while others are based on different existing elements. Patents are used to protect an invention. The motivation behind the appearance of new methods and objects stands in the need of a faster, cheaper, easier or more efficient way to perform a task. Inventions that are not practical are called “castle in the air” or “pie in the sky”.
