Patent registration is a crucial process for protecting intellectual property, especially for international companies looking to safeguard their innovations in India. The Indian patent system is governed by the Indian Patents Act, 1970, and the process involves several steps to ensure that the invention meets the criteria of novelty, inventiveness and industrial applicability.

Patent Registration in India

Patent registration in India involves a detailed procedure to secure exclusive rights over an invention. This process allows the patent holder to prevent others from making, using, or selling the invention without permission for a period of 20 years from the filing date.

Steps for Patent Registration in India

1. Patent Search

The first step is conducting a comprehensive patent search to ensure that the invention is unique and has not been previously patented. This involves checking existing patents and literature to confirm the novelty of the invention. Conducting a thorough patent search can prevent future legal conflicts and help in drafting a robust patent application.

2. Drafting the Patent Application

A well-drafted patent application is critical. It should include a detailed description of the invention, claims defining the scope of protection, drawings, and an abstract. Precision in drafting is essential to avoid future legal issues. The application must clearly outline the inventive steps and industrial applicability of the invention.

3. Filing the Application

The application can be filed through two primary routes:

• Paris Convention Route: If the company has already filed a patent application in its home country, it can file in India within 12 months from the priority date of the initial application. This route allows the applicant to claim priority from the first filing date.
• Patent Cooperation Treaty (PCT) Route: The company can file an international application under the PCT, designating India. This route simplifies the filing process when seeking protection in multiple countries.

4. Publication and Examination

After filing, the application is published in the Indian Patent Journal 18 months after the filing date. A request for examination must be filed within 48 months from the priority date. The Indian Patent Office then examines the application for compliance with legal requirements and patentability criteria. This includes checking the novelty, inventive step, and industrial applicability of the invention.

5. Responding to Examination Reports

If objections are raised, the applicant must respond promptly, addressing any issues raised by the examiner. This may involve amending the claims, providing additional information or clarifying details about the invention.

6. Grant of Patent

Once all objections are resolved, the patent is granted, and the grant is published in the Patent Journal. The patent holder can then enforce their exclusive rights to the invention.

Eligibility Criteria for Patent Registration

For an invention to be eligible for patent registration in India, it must meet the following criteria:

• Novelty: The invention must be new and not known to the public before the date of the patent application.
• Inventive Step: The invention must involve an inventive step that is not obvious to someone with knowledge and experience in the subject.
• Industrial Applicability: The invention must be capable of being used in some kind of industry.
• Not Prohibited by Law: The invention must not fall under non-patentable subject matter as outlined in Sections 3 and 4 of the Indian Patents Act.

Documents Required for Patent Registration

• Patent Application Form 
• Provisional or Complete Specification 
• Statement and Undertaking
• Declaration as to Inventorship 
• Request for Examination
• Power of Attorney (if filed through a patent agent)

Filing the Patent Application

Patent applications can be filed online or at patent offices in India. The choice of office depends on the applicant’s location or the principal place of business.

Post-Filing Process

Publication of Application

Upon filing, the patent application is published after 18 months from the filing date. This publication includes the details of the invention and allows for public scrutiny.

Request for Examination

The examination process begins only after a request for examination is filed, which must be done within 48 months from the priority date. The patent office examines the application for compliance with the requirements of the Patents Act.

Response to Examination Report

If the examiner raises objections, the applicant must respond within the stipulated time. This response may include amendments to the application or providing additional information to clarify the invention’s novelty and inventive step.

Opposition Proceedings

After publication and before the grant, third parties can oppose the patent application. This opposition is based on various grounds such as lack of novelty or inventive step. The applicant must defend the application during this period.

Conclusion

Patent registration in India is a comprehensive process that international companies must navigate carefully to secure their intellectual property rights. By following the prescribed steps and meeting the eligibility criteria, companies can protect their innovations and capitalize on their intellectual assets. Proper patent registration not only ensures legal protection but also enhances the commercial value of the invention, encouraging further innovation and investment.
