The application will be evaluated by the Patent Office for the novelty and inventive step, and whether it falls within the scope of the patentable subject matter. The examiner will then review the patent application, verify its validity, and determine whether or not it has industrial applications. If it is found to be viable, the applicant can then apply for a provisional or full patent. It is important to file a provisional application, as the filing date is the same as the priority date. To be eligible for a patent, you must have a product or invention with a practical application. This means that the invention must be novel, useful, and not obvious. Your invention must also be new and innovative in order to receive a patent. It should have a significant level of novelty and not be too simple. During this phase, you will have to submit a Form-28. Unlike the U.S. Patent Office, the Indian patent office requires a thorough review of your application.
