Patent Filing Process in Delhi

Delhi, as the capital of India and home to the Indian Patent Office (IPO) headquarters, is one of the most active hubs for intellectual property filings. Understanding the patent filing process in Delhi can save inventors months of delay and thousands of rupees in avoidable fees.

“A patent is not merely a legal document — it is a 20-year monopoly right that can define the commercial future of your invention.”

Step-by-Step: Patent Filing Process in Delhi

01 Idea Documentation & Invention Disclosure
Record your invention in detail with dates, diagrams, and technical descriptions. This creates evidence of your invention date.
02 Patent Search (Novelty Check)
Before drafting, conduct a thorough prior-art search to verify your invention is new and non-obvious. See Section 2 for a detailed guide on how to do a patent search in Delhi.
03 Drafting the Patent Application
A patent agent drafts the complete specification including claims, abstract, drawings, and description conforming to the Patents Act, 1970.
04 Filing at the Indian Patent Office
File your provisional or complete application online via the IPO e-filing portal or physically at the Delhi Patent Office (Boudhik Sampada Bhawan, Dwarka).
05 Publication of Application
Your application is published 18 months after the priority date in the Official Patent Journal unless early publication is requested.
06 Request for Examination (RCE)
File Form 18 or Form 18A (expedited) within 48 months of the priority date. Without this, the application is deemed withdrawn.
07 Examination & Responding to FER
The Patent Office issues a First Examination Report (FER). Applicants must respond within 12 months with arguments or amendments.
08 Grant of Patent
Once all objections are resolved, the patent is granted, published in the Patent Journal, and a patent certificate is issued.
Pro Tip from LexginFiling a provisional application first costs less and secures your priority date immediately. You then have 12 months to file the complete specification — ideal for startups still refining their product.

Design Filing in Delhi

Design filing in Delhi protects the visual appearance — shape, configuration, pattern, or ornamentation — of an article. Governed by the Designs Act, 2000, a registered design gives you a 10-year exclusive right (extendable by 5 years) over the aesthetic features of your product.

What Can Be Protected?

Any new and original design applied to a finished article of manufacture — including furniture, consumer electronics, apparel, packaging, household goods, and industrial components — can be registered through the design filing process in Delhi.

Design Filing Process in Delhi — Key Steps

1 Novelty & Originality Check: The design must not have been previously published or used in India or disclosed abroad before the filing date.
2 Prepare Drawings & Representations: High-quality line drawings or photographs showing all views (front, back, top, side, perspective) of the article are mandatory.
3 Classification Under Locarno: Identify the correct Locarno classification for your article — there are 32 classes and 223 sub-classes.
4 File Form 1 with the Design Office: Submit the application with drawings, applicant details, priority claim (if any), and the prescribed fee at the Design Wing, Delhi Patent Office.
5 Examination & Registration: The examiner reviews the application. If no objections, the design is registered and a Certificate of Registration is issued — often within 3–6 months.
Important NoteDesign protection only covers the visual features — not functionality. If your product has both novel functionality and a unique appearance, consider filing both a patent and a design application simultaneously.

Section 05

Patent Grant in India (Delhi)

The patent grant in India — specifically processed through the Delhi Patent Office for applicants in the northern region — is the culmination of the examination process under the Patents Act, 1970. A granted patent confers a 20-year exclusive right to the patentee to make, use, sell, or import the patented invention in India.

Criteria for Patent Grant in India

  • Novelty: The invention must not form part of the prior art globally.
  • Inventive Step: The invention must not be obvious to a person skilled in the relevant field.
  • Industrial Applicability: The invention must be capable of being used in an industry.
  • Patentable Subject Matter: Certain categories like mathematical methods, business methods, and abstract theories are excluded under Section 3 of the Patents Act.

Timeline for Patent Grant in India

The timeline from filing to patent grant in India varies widely:

Stage Typical Timeframe
Provisional Filing to Complete Specification Within 12 months
Filing to Publication 18 months (or earlier if requested)
Request for Examination (deadline) Within 48 months of priority date
First Examination Report (FER) 1–3 years after RCE
FER Response Deadline 12 months from FER date
Grant (after objections resolved) 3–7 years from filing (avg.)
Expedited Examination (Form 18A) As fast as 1–2 years
Annual Renewal FeesOnce granted, patents must be renewed annually from the 3rd year. Failure to pay renewal fees leads to lapsing of the patent. Lexgin offers automated patent annuity management to ensure your rights never lapse.
