All Inventions and Inventors of the World with the years & Country Belong.
What is Invention ?
An invention is a unique or novel device, method, composition or process. The invention process is a process within an overall engineering and product development process. It may be an improvement upon a machine or product or a new process for creating an object or a result. An invention that achieves a completely unique function or result may be a radical breakthrough. Such works are novel and not obvious to others skilled in the same field. An inventor may be taking a big step in success or failure.
Who is Inventor ?
Any person who made or Discovered any New project like Machine , appliance or Article is basically known as Inventor.The word inventor comes from the Latin verb invenire, invent-, to find. The system of patents was established to encourage inventors by granting limited-term, limited monopoly on inventions determined to be sufficiently novel, non-obvious, and useful. Although inventing is closely associated with science and engineering, inventors are not necessarily engineers nor scientists.
