Patent Filing in India 2026: Everything You Need to Know

Patent protection is a crucial step for inventors, startups, entrepreneurs, and established companies that want to secure exclusive rights to their innovations in India. As the Indian innovation ecosystem grows rapidly, understanding the patent filing landscape in 2026 — including procedures, costs, timelines, and strategic tips — has become more important than ever. This guide provides you with everything you need to know about patent filing in India.

What Is a Patent and Why Patent Filing in India is Important?

A patent is a legal right granted by the government that gives an inventor exclusive control over making, using, and selling an invention for a limited period of time — typically 20 years from the filing date.

Filing a patent in India helps inventors:

• Protect their invention from unauthorized use, copying, or commercialization. 

• Gain a competitive edge in the market.

• Attract potential investors or technology partners.

• Contribute to India’s innovation ecosystem, which has seen rising numbers of patent applications by Indian residents in recent years.

  
  

What is Eligibility Criteria to File a Patent in India?

Patent applications can be filed by:

• Individual inventors.

• Companies or organizations.

• Legal representatives or assignees of inventors.

The invention must be novel, non-obvious, and industrially applicable to qualify for patent protection under Indian law.

Types of Various Patent Applications

In India, you can file:

1. Provisional Patent Application

A provisional application is useful when your invention is still being developed. It establishes a priority date and gives you 12 months to prepare a complete, detailed specification.

Advantages include:

• Lower initial cost.

• Time to refine the invention before final filing.

  
  

2. Complete Patent Application

This includes full details about your invention, including all claims and specifications, and is filed either directly or after filing a provisional application.

Both applications follow the same legal pathway but differ in detail and timing.

Step-by-Step Process to file Patent in India

Filing a patent in India involves multiple stages:

Step 1: Patentability Search

Before filing, it’s recommended to conduct a patent search to ensure your invention is new and not already patented.

Step 2: Drafting the Application

You need to prepare several forms and documents, including:

• Form 1 (Application for grant).

• Form 2 (Specification).

• Form 3 (Statement and undertaking).

• Form 5 (Inventorship declaration).

A well-prepared specification is vital since it defines the scope of protection.

Step 3: Filing with the Indian Patent Office

Submit your application online via the Indian Patent Office (IPO) portal or physically at one of the regional IPO offices (Delhi, Mumbai, Chennai, or Kolkata).

Step 4: Publication

After filing, the application is usually published in the official Patent Journal after 18 months from the filing date or priority date. You can request early publication for an additional fee.

Step 5: Request for Examination (RFE)

You must request examination within 48 months of filing. The IPO will then assess patentability criteria such as novelty, inventive step, and industrial applicability.

Step 6: Responding to Examination Reports

The IPO may issue objections. You must respond with arguments or amendments to overcome these objections.

Step 7: Grant and Maintenance

If accepted, the patent is granted and valid for 20 years, subject to annual renewal fees.

Official Fees for Patent Filing in India

Patent filing fees depend on your applicant category (individual, startup, small entity, or large entity). Government filing fees are typically around ₹1,600 to ₹8,000 for the initial application, with additional costs for examination, publication, and professional charges.

Professional drafting and agent fees can range from tens of thousands to over ₹1,00,000, depending on complexity.

Startups and small entities often enjoy reduced fee concessions, which help encourage innovation.

Tips for better Patent Filing in India

• Hire a Registered Patent Agent: Expert drafting increases chances of acceptance.

• File Early: Establishing a priority date helps in competitive innovation spaces.

• Track Deadlines: Request examination and respond to objections on time.

• Consider International Protection: If you plan markets beyond India, explore PCT national phase filing within 31 months.
