Overview of Patent Registration in India
Secure your brand's identity with Kanakkupillai's Intellectual Property Services - Protect, Promote and Prosper.
Patent registration in India is a legal process that grants exclusive rights to an inventor over a new and useful invention. It ensures that no other individual or business can make, use, sell, or distribute the invention without the owner’s permission for a defined period.
For businesses, startups, and individual innovators, securing a patent is essential to protect original ideas, technologies, or processes from unauthorized use. In a competitive market, this protection helps maintain a unique position and prevents duplication by competitors.
A registered patent is more than just legal protection—it is a strategic business asset. It allows the owner to commercialise the invention, license it to others for royalties, or transfer ownership through sale. This creates opportunities for additional revenue and long-term value creation.
Patent registration also enhances credibility. It signals innovation, strengthens brand reputation, and increases investor confidence by demonstrating that the business owns and protects its intellectual property.
What is Patent Registration?
Patent registration grants the inventor the right to sell, manufacture, use, and process the invention. It also prevents others from making identical copies of the product. Patents registered by the Indian government provide legal protection, which can be used as evidence in court. In India, a patent is valid for up to 20 years, with renewal options depending on various factors.
Why is Patent Registration Important?
Patent registration is essential in India due to the following reasons:
- Protect your Creation: Patent Registration guards your innovation from unauthorised use and gives you exclusive rights to your creation.
- Validity: It protects your innovation from infringement for a fixed 20-year period of patent exclusivity.
- Proprietary Rights: Patent Registration allows the creator/inventor of the invention to charge extra for innovation. By registration, you can increase your company's profit.
- Sell or transfer patent rights: After registering your patent, you can sell, grant, or franchise it.
- Good Reputation: A registered patent boosts the inventor’s credibility in the product.
- Funding: A patent can attract investors or help secure funding, even if it only generates a small royalty.
What Can be Patented in India?
A patent can be obtained for a variety of inventions in India, including:
- Products: This category includes novel and creative physical objects, including manufactured goods, equipment, technologies, chemicals, and medications.
- Methods: Innovative processes or techniques for producing a good or completing a task. This could include innovative field techniques, industrial methodologies, or manufacturing processes.
- Machines: Patents are available for any novel, functional machines or mechanical inventions, including ones with inventive mechanics or parts.
- Manufactured Goods: Items that are made with a unique technique or have distinctive qualities are eligible for patent protection; where the appearance of such items is the key differentiator, design registration online may also be considered.
- Chemical Formulas: New and creative chemical substances, including pharmaceuticals, are patentable. Biotechnological discoveries: Patents are available for biological advances such as gene mapping, genetic manipulation and new biotechnology procedures.
- Software and Digital Innovation: Patent protection may be granted for inventions in the area of software and digital innovations, as well as those relating to computers.
Which Cannot be Patented in India?
You cannot patent everything. Some inventions are not eligible, such as:
- Discoveries of scientific principles or natural laws.
- Creative works like music, art, or literature (which may instead qualify for trademark registration online or copyright protection).
- Methods for games, business plans, or mental activities.
- Inventions were harmful to people, animals, or the environment.
- Inventions against public morality or order.

Various Patent Offices and Their Authority
There are four patent offices in India where one can apply for patent registration. The jurisdictions of these four offices differ from one another.

Who Can Register a Patent in India?
The following individuals or identities can file patent registration applications:
- The original creator of the invention.
- The rightful owner of the invention.
- The legal representative or assignee of a deceased inventor.
Where Can You Apply for Patent Registration in India?
Patent applications are filed at the relevant patent office using Form-1, and the necessary fee is charged at a patent-registered patent office. The following factors determine the jurisdiction of a patent office:
- Location of the applicant's home, place of business, or both (first mentioned applicant in the case of joint applications).
- The location of the birth of the invention.
- If the applicant (a foreign applicant) does not have a company or place of residence in India, they need to provide their address for service in India.
Forms to Be Filed
| Form | Purpose |
| Form-1 | It is one of the fundamental forms of patent registration in India. In the form, the following details need to be filled:
The applicant's name, address, and a few other fundamental facts must be entered into this form. |
| Form-2 | The invention title must be submitted using Form-2, followed by the applicant's name, address, nationality, and other details in the preamble to the description. |
| Form-3 | This form concerns the Undertaking and statement. The applicant must submit it either along with their application for patent registration or within six months after the application. |
| Form-5 | This form is used to identify the creators of the material that the current application is attempting to protect. Anything left out of the patent application will stay unclaimed and available to the general public. Therefore, don't let anything about your method or product go unclaimed. |
| Form-26 | If you hire a lawyer or authorise any other person to file the patent application on your behalf, this form discusses ‘Power of Attorney’ for your patent registration. |
| Form-9 | The procedure for applying for a patent is lengthy, but if you want it early, you can use Form-9 to request early publication. |
| Form-18 | The request for examination (Form 18) is mandatory and must be filed within 31 months of the priority or filing date, for applications filed on or after 15 March 2024. For applications filed before that date, the earlier 48-month deadline still applies. Missing this deadline means the application is treated as withdrawn under Section 11B(4), with no further remedy filing it as early as your budget allows is safer than waiting. |
| For-28 | This specific form pertains specifically to startups and small business enterprises, not to individuals. |
Furthermore, you also need to attach permission from the National Biodiversity Authority if the proposal uses biological material that was obtained from India. The source of biological material should be indicated in the specifications if any biological material is mentioned.

The Procedure of Patent Registration in India
In order to obtain a patent in India, it is necessary to carry out extensive research for patents in India and the registration procedure is broken down as follows:
Searching for Patents
Conduct a thorough patent search as the first step in determining whether the innovation is original. Looking up the invention's patentability. It is wise to conduct a comprehensive investigation into patentability to ascertain the possibility of obtaining a patent prior to applying for one in India. To ascertain patentability, visit http://ipindiaservices.gov.in/publicsearch. Remember that you don't need to do this step alone.
Create the Patent Specification
After the international search for the application is finished, the patent specification is written. Technical and legal claims made by the inventor may or may not be included in this paper. If there are no claims, the specification is tentative; if there are, it is comprehensive. The invention is described in detail, together with valuable examples and the optimal way to put it into practice, in the specification. When a patent specification is comprehensive and includes all of the inventor's claims, it is legally protected — which is why thorough patent proofreading before submission is strongly recommended.
Filing Your Patent Application
Once the patent specification is created, you can apply for a patent in India. Applications may be complete or preliminary, depending on the drafted specifications. The Provisional or Complete Specification is filed in Form 2 in compliance with the Indian Patent Act, whereas the Patent Application is filed in Form 1. You have a year to file a complete patent specification that contains the inventor's claims if you have previously completed provisional patent filing.
Making the Patent Opposition Public
Following filing, the Patent is published for public inspection in an official gazette. As long as they have a good cause, the public can raise an opposition to grant of patent because of its transparency.
Commencing the Patent Examination
A chosen patent examiner thoroughly reviews the application and issues a First Examination Report (FER) detailing any objections. Under the Patents (Amendment) Rules, 2024, you have 6 months from the date of the FER to file a complete response extendable by a further 3 months by filing Form 4 with the prescribed fee, for a maximum of 9 months from the FER date. This 9-month outer limit is absolute: Rules 24B(5) and (6) are specifically excluded from the general condonation-of-delay provision, so there is no remedy if you miss it without having filed Form 4 in time. In order to address these issues, known as patent prosecution, the examiner may call the applicant or representative to a hearing, which is now commonly conducted by video conference.
A patent is Awarded
The Patent is granted if all of the officer's concerns have been addressed. However, if the counterarguments do not persuade the examiner, the application is denied, and the applicant has to start over to obtain further protection in India.
Renewal of Your Expired Patent
Renewing your Patent is one of the final steps in getting one in India. A patent usually lasts for 20 years and must be renewed by the owner after 20 years for a nominal charge.
Form 27: The Statement of Working You Must File Even After Grant
Getting your patent granted isn't the end of your obligations. Under Section 146 of the Patents Act, every patentee (and any licensee) must periodically file Form 27, a statement declaring whether the patented invention is actually being worked manufactured, used, or commercially exploited in India.
Since a 2020 rule change, this is now filed once every three financial years covering that period, rather than annually, with a filing window that typically runs from 1 April to 30 September following the end of each three-year block, extendable by 3 months via Form 4. Failing to file Form 27, or filing false information, is a serious matter it's an offence under Section 122 of the Act, and non-working can also be cited as a ground for a compulsory licence application by a third party under Section 84.
What Does "Patent Pending" Actually Mean?
Once you've filed a provisional or complete specification, you can describe your invention as "Patent Pending", a public notice that an application has been filed, useful when talking to investors, licensees, or putting it on product packaging. It's worth being clear about what this status does and doesn't do: it puts the market on notice, but it doesn't stop anyone from using your invention while the application is pending, and you can't sue for infringement until the patent is actually granted. Once granted, though, protection is backdated to the date your complete specification was published so infringement during the pending period can still be pursued retroactively once you have the granted patent in hand.
Note: unlike the FER response deadline (6 months, extendable to 9), the 12-month deadline to convert a provisional specification into a complete one has no extension available under Section 9(1), miss it, and the application is automatically deemed abandoned, with no Form 4 remedy. Not every deadline in this process works the same way, and this is the one where there's no safety net.
Patent Registration Fees
| Applicant Category | Form 1 Filing Fee (E-Filing) | Form 18 Examination Fee (E-Filing) |
| Individual(s) / DPIIT Startup / Small Entity / Educational Institution | ₹1,600 | ₹4,000 |
| Large Entity ("Others") | ₹8,000 | ₹20,000 |
To claim the concessional rate, applicants other than a sole natural person must file Form 28 with supporting proof of eligibility without it, the application defaults to the large-entity fee, even for a genuinely small business.
Guidelines Regulating the Filing of Patent Applications;
Keep the following guidelines in mind while submitting a patent application:
- It is necessary to submit the patent application to the Indian Patent Office.
- The name of the inventor or creator shall be indicated in an application for a patent.
Patent Registration Validity in India
After a preliminary or final patent registration application is filed, an Indian-registered patent is valid for 20 years. After this period, the patent becomes public domain unless renewed.
What is Patent Renewal?
Patent renewal is the procedure by which a patent may be renewed once its corresponding renewal fee has been paid. A renewal fee shall be paid before the end date.
Can a Patent in India be Revoked/Cancelled?
As per Section 66 of the Patents Act, 1970, the patent registration in India can be revoked due to the following reasons in India:
The patent Registration in India may be cancelled due to the following reasons:
| What Happens | Governing Provision |
| Patent lapses for non-payment of renewal fees | Section 53(2)-the patent simply ceases to have effect; this is a lapse, not a formal "revocation" |
| Revocation on merits (lack of novelty, obviousness, insufficient disclosure, wrongful obtaining, etc.), via petition before the Appellate Board or High Court | Section 64 |
| Revocation by the Controller after a compulsory licence has been in force and the invention still isn't being worked | Section 85 |
| Revocation by the Central Government where the patent is mischievous to the State or prejudicial to the public | Section 66 |
Will my Invention be Protected Outside of India through Indian Patent Registration?
A patent registered in India only protects your invention within India, it doesn't extend automatically to other countries. To protect the same invention abroad, you generally have two routes: file a convention application directly in other Paris Convention member countries within 12 months of your first Indian filing date (not the grant/registration date), claiming priority from it; or file a single PCT (Patent Cooperation Treaty) application, which preserves your right to enter the national phase in over 150 member countries for up to 31 months from your priority date. The PCT route buys significantly more time to decide which countries to pursue and secure funding, which is why most applicants planning international protection use it rather than filing separate convention applications country by country.

India doesn't use the utility/design/plant classification some other countries use. Under the Patents Act, 1970, applicants choose from six application types depending on their situation: an ordinary application (a standalone new filing), a provisional application (secures an early priority date before the invention is fully developed, with 12 months to file the complete specification), a convention application (claims priority from an earlier application filed in another Paris Convention country), a PCT national phase application (entering India from an international PCT filing), a divisional application (splitting a single application covering more than one invention), and a patent of addition (for an improvement to an invention you've already patented). Filing under the wrong type can cost you your priority date, so it's worth confirming which one fits before you file.
Finding proof that there has been a previous understanding of the innovation before the date the patent application was filed is known as a prior art search.
On mutually agreeable terms, other parties may purchase the Patent and use the invention.
Therefore, rather than being positive privileges, patents are negative rights. A patent gives its owner the authority to forbid the creation, distribution, use, importation, or offering of the patented procedure, composition, or product for sale. A patent is not a positive right that gives its holder complete control over what they can do.
Every awarded Patent is only valid in the territory of the nation that granted it. Therefore, the Indian government's granted Patent is only valid within India.
