For a Patentability Search, a patent application must satisfy the following three criteria:
Novelty: This means that your invention must not have been made public in any way even before the date of the application.
Inventive Step: This means that your product or process must be an invention solution. It should not be a kind of invention that would be evident to a manufacturer.
Industrial Applicability: This criterion implies that it must be possible to manufacture the invention.
