What are Inventions and Discoveries?
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. Whereas, discovery is the act of detecting something new, or something previously unrecognized as meaningful.
