Obtaining a patent in India involves several steps, from identifying a patentable invention to receiving the grant of a patent. The process is governed by the Patents Act, 1970, and administered by the Controller General of Patents, Designs, and Trademarks (CGPDTM).
Step-by-Step Process
1. Determine Patentability
- Ensure that the invention fulfills the criteria of patentability:
- Novelty: The invention is new and has not been disclosed publicly anywhere in the world.
- Inventive Step: The invention involves a technical advancement or is not obvious to someone skilled in the field.
- Industrial Applicability: The invention can be applied to a practical industrial process or use.
- Verify that the invention is not excluded under Section 3 and Section 4 of the Patents Act (e.g., abstract ideas, natural laws, algorithms, or inventions against public morality).
2. Conduct a Patent Search
- Conduct a prior art search to ensure the invention has not already been patented or disclosed.
- Use resources such as:
- Indian Patent Office's InPASS (Indian Patent Advanced Search System).
- International databases like WIPO (World Intellectual Property Organization) or Google Patents.
3. Draft a Patent Application
- Draft a provisional application or a complete specification, depending on the invention's readiness:
- Provisional Application: Filed when the invention is still under development. It provides a filing date and gives the applicant 12 months to file the complete specification.
- Complete Specification: Filed when the invention is fully developed. It includes:
- Title of the invention.
- Field of invention.
- Background and objectives.
- Detailed description, claims, and drawings (if applicable).
4. File the Patent Application
- File the application with the Indian Patent Office (IPO) either online or physically.
- Forms to be submitted:
- Form 1: Application for a grant of a patent.
- Form 2: Provisional or complete specification.
- Form 3: Statement and undertaking regarding foreign applications.
- Form 5: Declaration of inventorship.
- Pay the prescribed filing fee, which varies based on the type of applicant (individual, startup, small entity, or large entity).
5. Publication of Application
- After filing, the application is published in the official Patent Journal after 18 months from the filing date or priority date.
- If early publication is desired, the applicant can request it using Form 9 (for early publication), and the application will be published within 1 month.
6. Request for Examination
- A patent application is examined only after a formal request for examination is filed using Form 18 or Form 18A (expedited examination for eligible applicants like startups or women inventors).
- The examination involves:
- Checking compliance with legal requirements.
- Assessing novelty, inventive step, and industrial applicability.
- Verifying against prior art.
7. Examination Report
- The examiner issues a First Examination Report (FER), listing objections (if any).
- The applicant must respond to these objections within 6 months, which can be extended by another 3 months upon request.
8. Pre-Grant Opposition (Optional)
- Any third party can file a pre-grant opposition to challenge the application after publication but before the patent is granted.
- Grounds for opposition include lack of novelty, prior disclosure, or non-patentable subject matter.
9. Grant of Patent
- If the Patent Office is satisfied with the responses and the invention meets all criteria, the patent is granted and published in the Patent Journal.
- The applicant receives a patent certificate, giving them exclusive rights to the invention for 20 years from the filing date.
10. Post-Grant Opposition
- Within 12 months of the patent grant, any interested party can file a post-grant opposition.
- The opposition board reviews the claims, and a decision is made to maintain, amend, or revoke the patent.
Documents Required
- Application forms (Forms 1, 2, 3, 5, etc.).
- Detailed description of the invention.
- Patent drawings (if applicable).
- Priority documents (for international filings under the Paris Convention or PCT).
- Power of attorney (if filed through an agent).
Timeline
The process can take 2-5 years, depending on the type of application, response to objections, and opposition proceedings. Expedited examination reduces this timeline significantly.
Costs
- Filing fees vary based on the type of applicant:
- Individual/Startup: Lower fees.
- Large Entity: Higher fees.
- Additional costs include professional fees for patent agents, legal consultation, and renewal fees after the grant.
Key Features of the Patent System
- Provisional Filing: Allows applicants to secure a priority date while completing the invention.
- Early Publication and Expedited Examination: Enable faster grant of patents for urgent or critical inventions.
- Opposition System: Ensures that only valid patents are granted.
