Step-by-Step Guide to Patent Registration in India

A patent is an exclusive statutory right granted by the government to an inventor for a novel, non-obvious, and industrially applicable invention, in exchange for full public disclosure. In India, the Patents Act, 1970 (amended from time to time, most recently by the Patents (Amendment) Rules, 2024 — notified on 15 March 2024) governs the grant, registration, protection, and assignment of patents. The Act is administered by the Office of the Controller General of Patents, Designs & Trade Marks (CGPDTM), operating under DPIIT, Ministry of Commerce and Industry.

What is a Patent?

A patent is a territorial, time-bound statutory right that excludes third parties from making, using, selling, offering for sale, or importing the patented invention in the country where the patent is granted. In India, the term of a patent is 20 years from the date of filing the application (Section 53), subject to the payment of renewal fees during the lifetime of the patent — calculated from the application filing date, but only becoming payable once the patent has been granted.

Why is the Patents Act, 1970 Important?

The Patents Act, 1970 replaced the colonial-era Indian Patents and Designs Act, 1911. Originally, it deliberately restricted product patents in pharmaceuticals, agrochemicals, and food in line with national industrial policy; the 2005 product-pharma transition aligned the regime with India's TRIPS obligations. Subsequent Patents (Amendment) Rules in 2016, 2017, 2019, 2020, and 2024 have progressively widened fee rebates for startups, simplified Form 5/Form 18 procedures, revised the Request for Examination timeline (now 31 months from priority/filing date under the 2024 Rules), rationalised Form 27 and Form 3 reporting cycles, and introduced an advance-renewal discount mechanism.

Objectives of the Patents Act, 1970:

• To encourage innovation and protect genuine inventors by granting exclusive commercial rights over their inventions.
• To balance inventor rights with public interest, particularly in pharmaceuticals, food, and essential goods.
• To disseminate technological knowledge by requiring complete public disclosure of the invention.
• To align India with the TRIPS Agreement and global IP treaties, including the Paris Convention and the Patent Cooperation Treaty (PCT).

Key Features of the Patents Act, 1970:

• Defines invention as a new product or process involving an inventive step and capable of industrial application (Section 2(1)(j)).
• Prescribes a 20-year term from the filing/priority date (Section 53), with renewal fees calculated from the filing date but only becoming payable once the patent has been granted (Section 142). No renewal fee is due in Year 1 or Year 2 of the patent term; fees begin from the 3rd anniversary (calculated from the filing date).
• Allows both provisional and complete specifications, enabling applicants to secure a priority date while refining the invention.
• Mandates Request for Examination (Form 18) within 31 months from the priority date or filing date (whichever is earlier) for applications filed on or after 15 March 2024 under the Patents (Amendment) Rules, 2024 — failing which the application is treated as withdrawn. (Applications filed before 15 March 2024 retain the prior prescribed deadline applicable at the time of filing.)
• Provides for pre-grant opposition under Section 25(1) — fileable by any person (no standing of commercial interest required) — and post-grant opposition under Section 25(2), which may be filed only by a person interested.
• Confers exclusive rights against making, using, selling, offering for sale, and importing the patented product or process (Section 48).
• Recognises Convention Application under Section 135 (Paris Convention priority) and PCT national-phase entry under Sections 7-9.
• Offers reduced government fees for natural persons, DPIIT-recognised startups, and small entities (Form 28).
• Excludes certain subject matter from patentability under Section 3 — notably Section 3(k) covering computer programs per se.
• Enables compulsory licensing under Section 84 in public-interest scenarios, especially for patented pharmaceuticals.
• Provides civil and criminal remedies for infringement under Sections 104-114 and Chapter XX.
• Form 27 (Working Statement) is now filed once every 3 financial years under the Patents (Amendment) Rules, 2024 — a significant compliance-relief provision for granted patents. (Pre-2024, Form 27 was filed annually.)
• Form 3 (Statement of Foreign Application) must now be filed within 3 months from the date of the First Examination Report (FER) under the Patents (Amendment) Rules, 2024, capturing details of corresponding foreign applications and patent outcomes at the time of examination — replacing the earlier periodic 6-month update cycle.
• Renewal fees paid in advance for 4 or more years attract a 10% discount on official fees under the Patents (Amendment) Rules, 2024 — providing a cost-effective mechanism for long-life patents.

Who Can Apply for Patent Registration?

The true and first inventor, their assignee, or their legal representative can file a patent application. Multiple applicants may file jointly, whether as joint inventors or as applicant-plus-assignee combinations. Foreign applicants without an Indian domicile are required to appoint an Indian patent agent registered with the IP India Patent Office to file and prosecute the application on their behalf (Section 7(2)).

Step-by-Step Patent Registration Procedure:

1. Filing the Application (Form 1 + Form 2):
   • Form 1 is the request for grant of patent, signed by the applicant and accompanied by the prescribed fee.
   • Form 2 is filed either as a Provisional Specification (placeholder for up to 12 months) or as a Complete Specification (full disclosure with claims).
   • Filing can be done electronically via the IP India e-Filing portal, by physical receipt at any of the four Patent Offices (Delhi, Mumbai, Chennai, Kolkata — with a Kolkata branch at Gangtok), or via the PCT national-phase entry route.
   • Form 5 (Declaration of Inventorship) must be filed alongside if the applicant is not the sole inventor.
   • Form 28 should be filed when claiming small-entity, startup, or natural-person fee status.
2. Publication in the Patent Office Journal:
   • Ordinarily, the application is published automatically 18 months after the priority/filing date.
   • Form 9 (Request for Early Publication) can expedite publication to within roughly one month of the request, thereby triggering provisional rights and accelerating examination.
3. Request for Examination (Form 18):
   • Must be filed within 31 months from the priority/filing date (whichever is earlier) for applications filed on or after 15 March 2024 under the Patents (Amendment) Rules, 2024 — failing which, the application is treated as withdrawn. (Earlier applications retain the applicable deadline as prescribed under the rules in force at the time of their filing.)
   • The reduced fee tier for natural persons, DPIIT-recognised startups, and small entities applies; the standard fee remains at the higher tier — refer to the IP India fee schedule for the latest notified figures.
4. First Examination Report (FER):
   • The Controller examines the application against novelty, inventive step, industrial applicability, and formal requirements.
   • The applicant must respond to the FER within 6 months (extendable by up to 3 months) using Form 4 amendments, claim corrections, and written submissions.
   • Under the Patents (Amendment) Rules, 2024, Form 3 (Statement of Foreign Application) must now be filed within 3 months from the date of this FER — disclosing details of all corresponding foreign applications and their patent-grant status at the time of Indian examination.
5. Opposition — Pre-Grant (Form 7A, any person) and Post-Grant (Form 7, person interested):
   • Pre-Grant Opposition under Section 25(1): any person may file Form 7A (initial opposition by any person — no commercial-interest standing required) before the date of grant of the patent.
   • Post-Grant Opposition under Section 25(2): a person interested may file Form 7 within 12 months of grant.
6. Grant of Patent and Renewal Cycle:
   • If objections are overcome and no opposition succeeds, the patent is granted and entered in the Register of Patents.
   • Renewal fees for the 3rd anniversary year onwards (calculated from the filing date) become payable upon grant. No renewal fee is due for Year 1 or Year 2 of the patent term. Fees are paid online through the IP India e-filing portal against the notified fee schedule (Form 30).
   • Under the 2024 amendment, a 10% discount on official renewal fees is available where renewal fees for 4 or more years are paid in advance.
   • Working statements must thereafter be filed via Form 27 once every 3 financial years, as revised under the 2024 amendment.

Contents of the Application (Complete Specification):

• Title of the invention, short and technically precise.
• Field of the invention identifying the technical domain.
• Background, citing prior art and the limitations of known solutions.
• Summary of the invention with the claimed technical advantage.
• Detailed description with reference to drawings where any are attached.
• Claims, defining the legal scope of protection sought.
• Abstract (≤ 150 words) for publication in the Patent Office Journal.
• Drawings referenced in the specification.
• Sequence listing in WIPO ST.26 format if the invention discloses nucleotide or amino-acid sequences.

Where the application corresponds to one or more foreign applications, Form 3 (Statement of Foreign Application) must be filed within 3 months from the date of the First Examination Report under the 2024 Rules.

Validity, Renewal, and Restoration:

Patent term is 20 years from the date of filing (or the priority date, whichever is earlier) per Section 53. Renewal fees are calculated from the filing date and become payable only after the patent has been granted (Section 142). No renewal fee is due for Year 1 or Year 2 of the patent term; renewal fees from the 3rd anniversary year onwards become payable from the date of grant, paid online through the IP India e-filing portal against the notified fee schedule. Where the patent is granted more than 3 years after filing, all accumulated renewal fees from Year 3 onwards fall due as a lump sum upon grant. Under the Patents (Amendment) Rules, 2024, a 10% discount on official renewal fees is available where renewal fees for 4 or more years are paid in advance.

If a patent lapses due to non-renewal, it can be restored within 18 months of the date of lapse by filing Form 15 under Section 60 of the Patents Act, together with the prescribed restoration fee and any missed renewal arrears. (Form 8 is reserved for addition of an inventor's name under Section 20, not for restoration.)

Subject Matter That Cannot Be Patented (Section 3 Exclusions):

• Inventions frivolous or contrary to public order or morality (Section 3(a)).
• Discoveries, scientific theories, or mathematical methods as such (Section 3(c)).
• New uses of known substances unless they demonstrably result in a significant enhancement in known efficacy (Section 3(d)).
• Atomic energy inventions are governed exclusively by the Atomic Energy Act, 1962 (Section 4).
• Plants and animals in whole or any part, other than microorganisms, and essentially biological processes for their production (Sections 3(h)-3(i)).
• Computer programs per se (Section 3(k)) — programs combined with novel hardware or a technical contribution may proceed.
• Mental acts, business methods, schemes, or rules as such (Section 3(k)).
• Aesthetic creations (cognizable under Design law, not Patent law).
• Traditional knowledge and matter prejudicial to public interest or religious sentiments (Section 3(p)).

Section 3(k) — Software and Business-Method Inventions:

Software-flavoured inventions are examined against the Guidelines for Examination of Patent Applications in the Field of Computer-Related Inventions (CRIs) currently in force. A pure algorithm, business method, or computer program by itself is not patentable; however, applications claiming a novel hardware component, a technical contribution to the prior art, or an inventive step integrated into a practical industrial application may proceed to grant. This distinction — software per se vs. software as an industrial solution to a technical problem — is where most AI/ML, fintech, healthtech, and SaaS inventions succeed or fail before the Indian Patent Office.

PCT (International) Route:

Applicants seeking protection in multiple jurisdictions typically file a PCT international application through the WIPO Patent Cooperation Treaty system within 12 months of the priority date, designating WIPO as the Receiving Office. The International Search Report is issued by ~16 months, and (optionally) an International Preliminary Examination Report by ~28 months. National-phase entry into India (and any other PCT contracting state) must be completed within 31 months from the priority date by filing the complete specification, Form 1, and the prescribed national fees.

Working Statements and Foreign Filing Updates — Key Changes under the Patents (Amendment) Rules, 2024:

Once a patent is granted, the patentee must file Form 27 (Working Statement) once every 3 financial years under the Patents (Amendment) Rules, 2024 — a substantial compliance-relief provision vs. the earlier annual cycle. The Form 27 disclosure confirms whether the patent is being worked in India on a commercial scale and whether public exigency requirements are being met. Similarly, where the Indian application corresponds to one or more foreign applications, Form 3 (Statement of Foreign Application) must now be filed within 3 months from the date of the First Examination Report — capturing the corresponding foreign filing numbers, jurisdictions, and patent-grant status at the time of Indian examination, in place of the earlier periodic 6-month update cycle.

Opposition Pathways at a Glance:

Pre-Grant Opposition (Section 25(1)) — Form 7A — any person may file (no commercial-interest standing required), at any time before the date of grant. Post-Grant Opposition (Section 25(2)) — Form 7 — any person interested may file within 12 months of grant.

Conclusion

Patent registration in India is a structured, multi-stage process anchored in the Patents Act, 1970 and the Patents (Amendment) Rules, 2024. For natural persons, DPIIT-recognised startups, and small entities, the reduced fee tier makes protection accessible, while Paris Convention and PCT routes allow global portfolio expansion at marginal incremental cost.

The smartest path is to file a strong provisional specification first, secure your priority date while continuing development, then move to a Complete Specification within 12 months — and remember to file Form 18 within the 31-month window under the 2024 Rules, File Form 3 within 3 months of the FER where foreign filings exist, pay renewal fees from Year 3 onwards (calculated from filing date) only after the patent is granted — using Form 30 / online payment, lock in the new 10% advance-renewal discount where eligible, and remember the opposition pathway now separates Form 7A (any person, pre-grant) from Form 7 (person interested, post-grant). If the patent lapses, restore it within 18 months via Form 15 under Section 60.
