A more thorough explanation:

Definition: Conception of invention refers to the formation of a clear and permanent idea of a complete invention in the mind of the inventor, which is then put into practice. This concept is important in patent law, as it helps determine the priority of invention.

Example: Let's say that a scientist has an idea for a new type of battery that can store more energy than any other battery on the market. The scientist spends months researching and experimenting until they finally come up with a working prototype. However, the conception of the invention occurred much earlier, when the scientist first had the idea for the battery in their mind.

Explanation: In this example, the conception of the invention refers to the moment when the scientist first came up with the idea for the battery. This idea was not yet a physical reality, but it was a clear and permanent idea in the scientist's mind. This idea then led to months of research and experimentation, which eventually resulted in a working prototype. The conception of the invention is important in patent law because it helps determine who was the first to come up with the idea for the invention, which can impact who is granted the patent.
