Secure exclusive rights over your invention for 20 years. Patent registration grants you legal authority to prevent others from making, using, selling, or importing your invention without permission — and creates a commercially valuable, transferable asset.
Patent registration in India is the formal legal process of obtaining exclusive rights over a new invention under the Patents Act, 1970, administered by the Office of the Controller General of Patents, Designs, and Trade Marks. A granted patent gives you the legal right to stop others from manufacturing, using, selling, or importing your invention in India for 20 years from the filing date.
Unlike copyright, which arises automatically on creation, patent rights must be explicitly applied for and granted after substantive examination. The trade-off is a public disclosure of your invention's technical details — in exchange for a legally enforceable monopoly. After 20 years, the invention enters the public domain, becoming freely available to all.
A granted patent is not just a legal shield — it is a commercial asset that can be sold, licensed, mortgaged, or used to attract investors and strategic partners. For startups and R&D-intensive businesses, a patent portfolio signals technical credibility and creates competitive moats that are difficult to replicate.
Prevent anyone from making your patented invention commercially in India without your authorisation.
Control who uses, offers for sale, or commercially exploits your invention within India's territory.
Block importation of your patented product or products made by your patented process from any country.
License your patent to third parties in exchange for royalties, creating recurring revenue from your invention without direct commercialisation.
Sue infringers in the High Court for injunctions, damages, and delivery up of infringing goods. Criminal penalties also apply under Section 63A.
An invention must meet all four mandatory criteria under the Patents Act. Failing any one disqualifies the application — regardless of how innovative the invention is.
The invention must be new — not disclosed, published, or used publicly anywhere in the world before the filing date. Even a single prior publication — a research paper, patent, website, or public presentation — destroys novelty. Any public disclosure before filing makes the invention ineligible.
The invention must involve a technical advance over prior art that would not be obvious to a person skilled in the same field. If someone with ordinary expertise in the field could have arrived at the same solution by routine experimentation, it lacks an inventive step and cannot be patented.
The invention must be capable of being made or used in some kind of industry — including agriculture. Purely aesthetic, theoretical, or abstract creations that cannot be manufactured or utilised in a practical industrial process are excluded. The invention must have a clear, practical utility.
Even if novel and inventive, an invention cannot be patented if it falls under Section 3 exclusions (mathematical methods, business methods, computer programs per se, traditional knowledge, methods of treatment, plants & animals) or Section 4 (atomic energy inventions).
Choose the right application type based on your invention's development stage, jurisdiction, and commercial goals.
Filed when invention is still in development. Establishes an early priority date and grants 12 months to file the complete specification. Does not require formal claims or abstract.
The full patent application with detailed specification, claims, abstract, and drawings. Filed for fully developed inventions. This is the application that leads directly to examination and grant.
A single Patent Cooperation Treaty (WIPO) application designating 150+ countries. Defers national phase entry to 31 months from priority date, allowing time to assess commercial viability before paying per-country fees.
Filed by foreign applicants within 12 months of the first application in a convention country (Paris Convention). Claims the priority date of the original foreign filing.
Filed when the original application contains more than one invention and the examiner requires division, or when the applicant voluntarily wishes to pursue different claim sets. Each divisional claims the parent's priority date.
Filed for an improvement or modification of an invention that is already the subject of an existing patent (parent). Term runs concurrently with the main patent and no additional renewal fees are payable during the parent's life. 50% fee discount under 2024 amendments.
The complete specification is the core legal document of your patent. It defines what you own — poor drafting permanently limits the scope of your patent rights.
A clear, concise title identifying the subject matter. Should be specific but not so narrow it precludes reasonable claim scope. Avoid proprietary names, brand names, or vague terms like "improved device."
Technical field of the invention and a description of the prior art with its limitations. Establishes the technical problem being solved and contextualises the inventive step. Should cite relevant prior publications.
A complete, detailed disclosure of the invention — how it works, how to make it, and how to use it. Must enable a person skilled in the art to reproduce the invention. This is the "best mode" disclosure requirement. Cannot add new matter after filing.
The most legally critical part. Claims define the exact scope of your exclusive rights — they are the "metes and bounds" of your patent. Every element must be supported by the description. Narrow claims are easier to obtain; broad claims offer wider protection but face more examination challenges. Professional drafting is essential.
A concise summary (150–250 words) of the invention covering the technical field, problem addressed, solution, and principal uses. Used for information purposes in patent databases — does not define the scope of protection (claims do).
Technical drawings, flowcharts, schematics, or chemical formulas — required whenever the invention's description cannot be fully understood in words alone. Each drawing must be referenced in the description. For mechanical, electronic, and process inventions, drawings are practically always required.
Patent specifications are permanent legal documents. Claims cannot be broadened after filing — only narrowed. A poorly drafted specification that fails to disclose all embodiments of the invention, or claims that are too narrow or too vague, permanently weakens your patent's commercial value. An improperly drafted specification cannot be corrected after the fact — the protection you get is determined entirely by what is in the application on the day you file.
Primary application form containing applicant and inventor details, title of invention, address for service, declaration of right to apply, and signatures. Basis of the entire application.
The complete specification including title, description, claims, abstract, and drawings (if applicable). The most critical document — must be professionally drafted to ensure maximum protection.
A declaration by the inventor(s) that they are the true and first inventors of the invention claimed in the specification. Must be filed with the complete specification or within 1 month of filing.
Paid online at ipindiaonline.gov.in. ₹1,600 (individual/startup/MSME/educational institution) or ₹8,000 (large entity), for up to 30 pages and 10 claims. Additional fees for excess pages and claims.
Statement disclosing details of corresponding patent applications filed in other countries — including application numbers, filing dates, and status. Must be filed with the application or within 6 months. Updated again within 3 months of FER issuance.
If the applicant is not the inventor, an assignment deed or endorsement of right from the inventor(s) is required. Must be authenticated and signed by all parties.
Required to claim reduced government fees. Accompanied by DPIIT startup recognition certificate, MSME registration, or institutional recognition documents.
Authorises a registered patent agent to file and prosecute the application on the applicant's behalf. Required when not filing personally.
Certified copy of the earlier foreign application establishing the priority date. Required for convention applications under Section 135. Must be filed within 18 months of the priority date.
Written permission from the National Biodiversity Authority (NBA) required for inventions involving biological material from India. Must be obtained before the grant of patent.
Before committing resources to a full application, conduct a thorough prior art search across InPASS, Google Patents, WIPO, and USPTO. Identify similar patents, assess novelty and inventive step, and confirm the invention does not infringe any active patents. A professional search report saves significant cost and time by identifying issues before — not after — filing.
Prepare the complete specification (Form-2) with all required elements: title, technical field, background, detailed description, claims, abstract, and drawings. Claim drafting is the most critical step — broad, well-structured claims maximise protection while navigating around prior art. Claims cannot be broadened after filing. This stage typically takes 2–4 weeks for a complex invention.
Submit Form-1 (application), Form-2 (complete specification), Form-5 (declaration of inventorship), and other applicable forms at ipindiaonline.gov.in. Determine jurisdiction based on your place of business or residence — four offices: Mumbai, Delhi, Chennai, Kolkata. Pay government fees online. The system generates a diary number immediately upon submission — this is your official filing date and priority date.
Under Section 11A, the application is published in the Indian Patent Office Journal 18 months from the filing or priority date (whichever is earlier) — making the full specification publicly accessible. If you need earlier publication (to enforce rights against infringers or attract investors), file Form-9 (Request for Early Publication) with the prescribed fee. Publication is the trigger for pre-grant opposition proceedings.
Examination does not happen automatically. The applicant must file a Request for Examination (Form-18) to trigger the examination process. For applications filed on or after 15 March 2024, the RFE must be filed within 31 months from the priority date. For earlier applications, the deadline is 48 months. Failure to file RFE results in deemed withdrawal under Section 11B(4). File the RFE as early as possible — the earlier it's filed, the sooner the examination queue begins.
After the RFE, the Patent Office assigns an examiner who reviews the application against the Patents Act. The examiner issues a First Examination Report (FER) setting out objections — citing prior art against novelty, questioning inventive step, raising formal deficiencies, or objecting to claim scope. The applicant has 6 months from FER issuance to respond (extendable by 3 months via Form-4). The response must address each objection by amending claims, providing arguments, submitting evidence, or requesting a hearing. If all objections are resolved, the patent is allowed.
After publication, any person may file a representation against the application (pre-grant opposition) on specific grounds — lack of novelty, prior use, non-patentable subject matter, etc. Under the 2024 amended rules, the Controller first assesses whether a prima facie case is made out before notifying the applicant. The applicant then has 2 months to file a reply statement. Pre-grant opposition filing now requires a fee of ₹4,000 (individual) / ₹20,000 (others) — introduced to reduce frivolous oppositions.
Once all examination objections are resolved and no pre-grant opposition is pending, the patent is granted. The patent is entered in the Patent Register and published in the Patent Journal. The applicant receives a Patent Certificate — the formal grant document. The 20-year protection term runs from the original filing date. Rights are enforceable retroactively from the date of publication.
Within 12 months of the patent grant, any interested person may file a post-grant opposition before an Opposition Board. Grounds are similar to pre-grant opposition. The Opposition Board (consisting of senior examiners) makes a recommendation to the Controller, who makes the final decision. Post-grant opposition filing fee: ₹20,000 (individual) / ₹40,000 (large entity) under 2024 Rules.
To keep the patent in force throughout its 20-year term, annual renewal fees must be paid from the 3rd year onwards, whether the application is pending or the patent is granted. Fees increase over time — starting at ₹800/year (individual, Year 3) and reaching ₹15,000+/year in the final years. Non-payment results in automatic lapse. Under 2024 Rules, a 10% discount is available if renewal fees are paid in advance for at least 4 years. Form-27 (working statement) must also be filed every 3 years after grant.
