Although Invention and Innovation relate to novelty and newness, there are certain differences between the two. Innovation brings about creativity, and when this applied rightly, it brings about the creation of something new, something contrary to an already existing custom or tradition.
On the other hand, the invention is the new product, process, or mechanism produced, which gives the creator a patent so as to stop others from using or selling the invention. Inventions are usually products of innovations. Innovation goes beyond the creation of something new; it also requires ideas that will make what has been produced reach those that need it.
An Invention is basically something that hasn't been used anywhere in the world i.e., something new, fresh, etc. In contrast, what some consider being innovations might be old ideas and processes in some places. While the invention is the creation of something new, the use of an invented product for other purposes can be considered as innovation.
