Inventions & Discoveries

An invention is a new form, composition of matter, device, or process. Some inventions are based on pre-existing forms, compositions, processes or ideas. Other inventions are radical breakthroughs which may extend the boundaries of human knowledge or experience.

Inventors create or discover new methods, forms, devices or other useful means. The system of patents was established to encourage inventors by granting limited-term monopoly on inventions determined to be sufficiently novel, non-obvious, and useful.
