Patent Examination in India: Your Roadmap from Filing to Grant

Filing a patent application is an important milestone, but it does not guarantee patent protection. Before a patent can be granted in India, the application must undergo a detailed examination process where the invention is assessed for novelty, inventive step, industrial applicability, and other legal requirements of the Patents Act, 1970.

If you’ve filed a patent in India and are waiting for it to be granted, here’s the reality: filing is only the starting point. The real test lies in the examination process, where your invention is scrutinized for legal and technical compliance. Understanding how the examination process works can help inventors, startups, and businesses navigate the patent journey more strategically and improve their chances of securing a grant.

From Filing to Publication

Once a patent application is filed, either with a provisional or complete specification, it is generally published after 18 months from the priority date. Publication makes the application available to the public and marks an important step toward examination.

If you want to move faster, you can request early publication. This option is often used by many startups and technology companies that want to accelerate patent prosecution, support commercial discussions, and enhance market visibility around their innovation.

Request for Examination (RFE): A Critical Step

Unlike in some jurisdictions, patent applications in India are not examined automatically. The applicant must file a Request for Examination (RFE) before the Patent Office to begin the substantive examination.

For applications filed on or after 15 March 2024, the time limit for filing an RFE has been reduced from 48 months to 31 months from the priority date or filing date, as applicable.

Missing this deadline can result in the application being deemed withdrawn, making this one of the most critical procedural requirements in the patent grant process.

India also offers an expedited examination route for eligible applicants, including startups, MSMEs, and applicants covered under certain international agreements. This route can significantly shorten examination timelines.

First Examination Report (FER): Where the Action Begins

After the Request for Examination (RFE) is filed, the Patent Office assigns the application to an examiner who reviews it based on several statutory requirements, including:

• Novelty
• Inventive step
• Industrial applicability
• Patentable subject matter under Sections 3 and 4 of the Patents Act

The examiner’s findings are communicated through a First Examination Report (FER), which lists any objections that must be addressed before the application can proceed toward grant.

Example Scenario

Imagine you’ve developed a mobile application that predicts stock market trends using advanced algorithms. The examiner may raise an objection under Section 3(k) of the Patents Act, arguing that the invention constitutes a mathematical method, business method, or computer program per se.

To overcome such objections, applicants often need to demonstrate a specific technical effect or technical contribution beyond the algorithm itself—for example, improved hardware efficiency, reduced data transmission, or enhanced user interface interaction.

Common Objections Raised in FERs

Patent applicants frequently encounter objections relating to:

• Lack of novelty due to prior art disclosures
• Lack of inventive step or obviousness
• Insufficient disclosure of the invention
• Lack of clarity, conciseness, or support in the claims
• Non-patentable subject matter under Sections 3 and 4
• Formal or procedural deficiencies in documentation

Understanding these common objections early can help applicants prepare stronger patent specifications and prosecution strategies.

Responding to the FER

The FER stage is where legal strategy meets technical clarity. Following the 2024 amendments, an applicant must place the application in order for grant within six months from the date of issuance of the FER. Failure to comply within this period may result in the application being deemed abandoned.

To address the objections raised in the FER, applicants may:

• Amend claims to distinguish the invention from prior art
• Provide technical and legal arguments supporting patentability
• Clarify ambiguous language in the specification
• Submit supporting evidence where necessary

A well-reasoned response can significantly improve the likelihood of obtaining a patent, while an inadequate response may lead to refusal.

How Long Does Examination Take?

One of the most common questions among patent applicants is how long examination takes. The timeline can vary depending on factors such as the technology field, workload at the Patent Office, and whether ordinary or expedited examination is requested.

Under the ordinary examination route, the FER may be issued several months (i.e., 12 to 24 months) to a few years after filing the RFE. In contrast, expedited examination can substantially reduce the waiting period (1 to 3 months), helping applicants reach patent grant more quickly.

Hearing Before the Controller

If objections remain unresolved after considering the applicant’s response, the Controller may issue a hearing notice, providing the applicant with an opportunity to present arguments before a final decision is made.

The hearing allows applicants to explain technical aspects of the invention, address outstanding concerns, and propose further amendments if necessary. Based on the submissions made during the hearing, the Controller may:

• Grant the patent
• Request additional amendments
• Refuse the application

For many applicants, the hearing represents the final opportunity to overcome objections and secure patent protection.

Opposition Proceedings: Pre-grant and post-grant

India’s patent system provides mechanisms for third parties to challenge patents at different stages.

Pre-Grant Opposition

Any person may file a pre-grant opposition from the date of publication in the Patent Journal up to the patent’s grant. The opposition may be based on grounds such as lack of novelty, obviousness, wrongful obtaining, or non-patentable subject matter.

Post-Grant Opposition

Once a patent is granted, an interested person may file a post-grant opposition within 12 months from the date of publication of the patent grant in the official journal.

Real-Life Example

In the pharmaceutical sector, competitors frequently use pre-grant opposition proceedings to challenge patents that claim minor modifications of existing drugs, arguing that the invention lacks novelty, inventive step, or enhanced efficacy.

Case Law Insight: Novartis AG v. Union of India

One of the most influential patent decisions in India is the Supreme Court’s ruling in Novartis AG v. Union of India.

In this case, the Court rejected a patent application for a modified form of a cancer drug because the applicant failed to demonstrate a significant enhancement in therapeutic efficacy as required under Section 3(d) of the Patents Act.

The decision clarified that merely discovering a new form of a known substance is insufficient for patent protection unless the applicant can establish enhanced efficacy. The ruling continues to influence examination standards for pharmaceutical and chemical inventions and serves as an important precedent in assessing incremental innovations.

Conclusion

The patent examination procedure in India is rigorous, time-sensitive, and highly technical. Securing a patent requires more than simply filing an application, it demands a clear demonstration that the invention satisfies the statutory requirements of patentability and procedural compliance.

Inventors, startups, and businesses that proactively manage examination deadlines, draft strong patent specifications, and respond effectively to objections significantly improve their chances of obtaining valuable patent protection. Understanding the patent examination process is therefore essential to transforming an innovative idea into an enforceable intellectual property asset.
