Patent Filing in India: A Step-by-Step Guide for Inventors

India's patent regime under the Patents Act, 1970, has seen significant growth, with over 90,000 patent applications filed in 2024 alone.

What is Patentable?

• A new product or process

• Involving an inventive step

• Capable of industrial application

• Not falling under excluded categories (Section 3 & 4)

Steps for Patent Filing in India

Step 1: Patentability Search
Conduct a prior art search to ensure your invention is novel. Use the Indian Patent Office database or hire a patent professional.

Step 2: Drafting the Patent Specification

• Title of invention

• Field of the invention

• Background and prior art

• Detailed description

• Claims (the most critical part)

• Abstract

• Drawings (if applicable)

Step 3: Filing the Application
File at one of the four Patent Offices: Delhi, Mumbai, Chennai, or Kolkata. You can file:

• Provisional application (cheaper, 12-month priority)

• Complete application

• PCT international application

Step 4: Publication
The application is published 18 months from filing. Request early publication for faster processing.

Step 5: Examination
Request examination within 48 months. The Controller issues a First Examination Report (FER). Respond to objections within 6 months.

Step 6: Grant
If all objections are resolved, the patent is granted and published in the Patent Journal.

Costs Involved

• Government fee: ₹1,600 (individual) to ₹8,000 (company) for filing

• Examination fee: ₹4,000 (individual) to ₹20,000 (company)

• Professional fees: ₹30,000 – ₹1,00,000+

Timeline
Typically 3-5 years from filing to grant in India.

Common Reasons for Rejection

• Lack of novelty (prior art exists)

• Obviousness (not inventive)

• Insufficient disclosure

• Subject matter excluded under Section 3
