Filing a patent in India is a legal process through which an inventor or applicant seeks exclusive rights over their invention, ensuring that others cannot make, use, or sell the invention without permission for a specific period. The process is governed by the Patents Act, 1970, and administered by the Patent Office under the Ministry of Commerce & Industry. Here’s a step-by-step guide on how to file a patent in India: Step 1: Verify Patentability Before you begin the process, ensure that your invention meets the patentability criteria: Novelty: The invention must be new and should not have been disclosed in any prior art. Inventive Step: The invention must involve an inventive step, meaning it should not be obvious to someone skilled in the relevant field. Industrial Applicability: The invention must be capable of being made or used in an industry. Not excluded from patentability: Some items are excluded from patentability, such as abstract ideas, scientific principles, and inventions related to atomic energy. Step 2: Conduct a Patent Search Perform a patent search to ensure that your invention is novel and hasn't been patented already. The Indian Patent Office provides a search facility on its website, or you can use WIPO (World Intellectual Property Organization) or other patent databases. A patent search helps avoid unnecessary filing costs and identifies prior art. Step 3: Prepare the Patent Application The next step is to prepare and file the patent application with the Indian Patent Office. The application includes the following components: Title of the Invention: A brief and descriptive title. Abstract: A summary of the invention’s technical field, purpose, and main aspects. Detailed Description: A complete description of the invention with drawings, diagrams, or flowcharts (if necessary). Claims: The legal scope of the patent, outlining the aspects of the invention for which protection is sought. Drawings: If applicable, technical drawings or diagrams explaining the invention. Types of Patent Applications: 1. Provisional Patent Application: This is a temporary application filed when the invention is not yet fully developed. It provides a filing date and gives you 12 months to file a complete application. The provisional application must include a basic description of the invention. 2. Complete Patent Application: This is the final application that includes detailed information about the invention, including claims and drawings. It can be filed directly, or within 12 months of filing a provisional application. 3. PCT (Patent Cooperation Treaty) Application: If you intend to file for patent protection in other countries, you may file an international application under the PCT. Step 4: Filing the Patent Application The patent application can be filed online through the Indian Patent Office’s e-filing portal or manually at one of the Patent Office branches (Kolkata, Delhi, Mumbai, or Chennai). The online method is faster and more convenient. Fee: A prescribed filing fee is required for both provisional and complete applications. The fee varies based on the applicant’s status (individual, small entity, or large entity). Step 5: Application Examination Once the application is filed, it will be assigned to a Patent Examiner for examination. This is a crucial stage in the patent process: Request for Examination (RFE): After filing the complete application, you must file a separate request for examination within 48 months from the filing date or priority date. The examiner will review the application, ensuring it meets all requirements and checking for novelty, inventive step, and industrial applicability. If the examiner finds any issues, they will issue a First Examination Report (FER), which may raise objections. The applicant must respond to these objections within a specified period. Step 6: Respond to Examination Report (If Any) If the Patent Office raises any objections in the FER, the applicant must provide a response addressing the concerns raised. You may be asked to amend the claims or clarify the invention’s details. In some cases, an oral hearing may be requested to explain the application further. Step 7: Patent Grant or Refusal If the examiner is satisfied with the response and finds the invention meets all the criteria, the patent will be granted. Once granted, the patent will be published in the Patent Journal, making it available to the public. This publication happens 18 months after the filing date. If the examiner still raises concerns after the applicant’s response, the application may be refused. Step 8: Patent Maintenance After the patent is granted, you must pay annual renewal fees to maintain the patent. These fees are required to keep the patent valid throughout its term (20 years from the filing date). If you fail to pay the renewal fee, the patent may lapse. Step 9: Enforcing Your Patent Once granted, a patent gives the owner the exclusive right to use, sell, or license the invention. If someone uses the patented invention without your permission, you can enforce your patent by taking legal action, including: Filing a suit for infringement in the court of law. Sending a cease-and-desist letter. Summary of Key Steps: 1. Verify patentability of the invention. 2. Conduct a patent search to check novelty. 3. Prepare and file the patent application (provisional or complete). 4. File the application either online or manually with the Patent Office. 5. Request for examination of the application. 6. Respond to objections, if any, raised by the examiner. 7. If the patent is granted, pay annual renewal fees to maintain the patent. Patent Filing Fees: Individual (Natural Person) / Startup / Small Entity: Lower fees. Large Entity (Corporation): Higher fees. Important Documents Required: Form 1 (Application form) Form 2 (Provisional/Complete Specification) Form 3 (Statement and Undertaking under Section 8 regarding foreign filings) Form 5 (Declaration of inventorship) Power of Attorney (if the application is filed through a patent agent) Conclusion: The process of filing a patent in India involves several steps, starting with confirming the patentability of the invention and ending with its grant and maintenance. The process can take anywhere from 2 to 5 years, depending on the complexity and nature of the application. It's crucial to ensure that all details are accurate and the claims are clear to avoid delays or rejections. It's highly recommended to seek the assistance of a patent attorney or agent to navigate this process, especially when it comes to drafting the application and responding to objections.

Dear Client, The Patents Act of 1970 is the law which puts forth the process for patent filing in India which in turn includes a number of stages to see that the invention is novel, is useful, and does not fall into the obvious category.

This also helps in the patent grant evaluation. Filing of Application: The at large the applicant will present to the Indian Patent Office (IPO) either a digital or a hard copy of the patent application. Also the application may be submitted as a provisional or full specification. A provisional application files a date of priority and also provides a period of 12 months to file the full specification. A full description of the invention and its claims. Publication of Application: After 18 months from the issue date or priority date the application is published in the Patent Journal unless the applicant requests for early publication. Request for Examination (RFE): The application will not be processed at our initiative. As a patentee you must put in a request for examination (Form 18/18A) within 4 years of the priority date or filing date. At that point the Controller will assign the application to an examiner. Examination and First Examination Report (FER): The examiner looks at if the invention fulfills the requirements of novelty, innovative step, and industrial applicability. We issue FER which point out any issues. Response to FER and Hearing: The application must reply to objections within the given time frame which is usually 6 months and may be extended by a further 3. Also at times a hearing will be held before the Controller. Grant of Patent: If all issues are resolved the patent is granted and published in the Patent Journal.
