Permanent Patent in India

The term “Permanent Patent” is commonly used to describe long-term patent protection, but Indian patent law does not provide a permanent or lifetime patent.

Under the Patents Act, 1970, the term of a patent granted in India is generally 20 years from the date of filing of the patent application, subject to the provisions of the Act. A patent cannot legally be guaranteed as a permanent right in India.

Clarification

What Does “Permanent Patent” Mean?

“Permanent Patent” is not an official category of patent under Indian patent law.

A patent is a statutory right granted for a limited period in exchange for disclosure of the invention. During the period in which the patent remains in force, the patentee can exercise the rights provided by the Patents Act, subject to statutory conditions and limitations.

Once the statutory patent term expires, the patent ceases to provide patent protection for the claimed invention. The Patents Act expressly provides that after expiry of the patent term, the subject matter covered by the patent is no longer entitled to protection under that patent.

Is a Permanent Patent available in India? No. There is no provision under the ordinary Indian patent system for obtaining a patent that remains valid permanently or for the lifetime of the inventor. The legally accurate description is patent protection for the statutory term — generally 20 years from filing, subject to the Patents Act.

Term

How Long Does a Patent Last in India?

Term

Normal Statutory Term

20 years from the date of filing of the patent application, subject to the provisions of the Patents Act.

PCT

PCT International Application

Generally 20 years from the international filing date for an application under the PCT designating India.

From

Counted From Filing Date

The 20-year period is not counted from the date of grant. It is generally calculated from the relevant filing date specified under the Patents Act.

Clear Distinction

Permanent Patent vs Regular Patent

There is no legal distinction because permanent patent is not a separate statutory category.

Point	Permanent Patent	Indian Patent
Legal category	Not a separate category	Statutory patent
Validity	No permanent validity available	Generally 20 years from filing
Governing law	—	Patents Act, 1970
Patent examination	—	Required
Renewal requirements	—	Applicable renewal fees must be paid
After expiry	—	Patent protection ends

A service provider should not advertise “Lifetime Patent”, “Permanent Patent Guarantee”, “Patent valid forever” or “Unlimited patent protection” as if these were statutory patent rights in India.

Rights

What Protection Does a Patent Provide?

A granted patent gives the patentee statutory rights in relation to the patented invention.

The scope of the right depends on the patent claims and whether the invention is a product or process. Subject to the Patents Act, Section 48 provides exclusive rights to prevent certain unauthorised acts concerning a patented product or process.

Patent protection may allow a patentee to take action against unauthorised commercial exploitation falling within the scope of the patent. Patent rights are therefore not absolute or unlimited — they depend on claims, validity, statutory exceptions, licences and other applicable provisions.

Patentability

What Can Be Protected by a Patent?

A patent may be granted for an invention that satisfies the requirements of Indian patent law.

Novelty

The invention must be new and must satisfy the statutory novelty requirement. Prior public disclosure can affect patentability.

Inventive Step

The invention must involve an inventive step as defined under the Patents Act. It should not simply be an obvious development for a person skilled in the relevant field.

Industrial Applicability

The invention must be capable of being made or used in an industry.

Patentable Subject Matter

The invention must not fall within the categories specifically excluded under the Patents Act (including Sections 3 and 4).

The Process

Patent Registration Process

A patent application follows a statutory process before the Indian Patent Office.

Identify the Invention

Document technical problem, existing technology, proposed solution, features, working principle, advantages and drawings where necessary.

Prior-Art Search

Search existing patents and publications to assess novelty, inventive step and potential claim scope. A search does not guarantee grant.

Determine Patentability

Assess novelty, inventive step, industrial applicability, patentable subject matter and statutory exclusions.

Prepare Specification & File

Draft specification (title, background, description, claims, abstract). File with provisional or complete specification. Complete within 12 months if provisional.

Publication

Applications are generally published after the statutory publication period. Early publication may be requested where eligible.

Examination & Objections

Request for examination is required. Examiner may raise objections on novelty, inventive step, subject matter, disclosure, claims and formality. Response and amendment may be needed.

Hearing & Grant

Hearing may be scheduled where required. If requirements are satisfied, the patent may be granted. Grant is not automatic and cannot be guaranteed.

After Grant

Patent Renewal & What Happens After Expiry

Renew

Renewal Required

A patent does not remain in force merely because it has been granted. Renewal fees must be paid according to the prescribed schedule. Failure to pay can result in cessation of the patent right.

Extend

Beyond 20 Years?

As a general rule, the statutory term is 20 years from the relevant filing date. There is no ordinary procedure to simply renew a patent indefinitely and convert it into a permanent patent.

Expire

After Patent Expiry

When the term expires, the patent right ceases. The subject matter is no longer protected by that patent. Other IP rights (trademark, copyright, design, trade secrets) may still be relevant to different aspects of a product or business.

Important Points

Key Points to Keep in Mind

No permanent or lifetime patent is available under ordinary Indian patent law.

A mere business idea does not automatically qualify for patent protection.

Computer programme per se is excluded; software-related inventions need careful technical assessment.

Public disclosure before filing can create serious novelty and patentability issues.

A provisional application does not itself create a granted or permanent patent — complete specification within 12 months.

Filing does not guarantee grant. No service can guarantee permanent protection or a particular examination outcome.

Important Legal Disclaimer

The expression “Permanent Patent” is used on this page only as a service/search term and does not represent a separate statutory category of patent in India.

Indian patents are governed primarily by the Patents Act, 1970 and the applicable Patents Rules, 2003, as amended. The general statutory term of an Indian patent is 20 years from the date of filing, subject to the applicable provisions, including renewal requirements.

No service provider can legally guarantee a permanent patent, guaranteed grant, guaranteed patentability or a particular examination outcome. Patentability, prosecution, grant, validity and enforcement depend on the specific invention, prior art, specification, claims, examination and applicable law. Government fees, forms, rules and procedures may change. Applicants should verify the latest requirements through the Indian Patent Office / IP India before filing.

FAQs

Frequently Asked Questions

Clear answers about permanent patent and the statutory term in India.

No. Indian patent law does not provide a permanent or lifetime patent. The general patent term is 20 years from the filing date, subject to the Patents Act.

The statutory term is generally 20 years from the date of filing of the patent application (or international filing date for PCT applications designating India).

No. Renewal fees maintain the patent during its statutory term, but they do not extend the patent indefinitely beyond the applicable statutory term.

The patent can cease to have effect according to the applicable provisions concerning non-payment of renewal fees.

No. Filing an application does not guarantee grant. The application is examined and must satisfy the applicable legal requirements.

No ordinary Indian patent can be granted as a lifetime patent.

No. A provisional specification does not itself create a permanent or granted patent. A complete specification must generally be filed within 12 months where the application was initially filed with a provisional specification.

No. Once the statutory patent term has expired, the patent cannot ordinarily be kept alive through ordinary renewal.

A patent and trademark are separate rights. A trademark may continue under its own statutory framework if it is validly registered and renewed, but it does not extend the expired patent.

The expiry of a patent does not create a general right to obtain another patent for the same already-disclosed invention. Patentability must be assessed under the law, including novelty and prior-art requirements.

A computer programme per se is excluded from patentability. Computer-related inventions must be assessed based on the actual technical features and applicable examination principles. Simply calling software “innovative” does not establish patentability.

Patent applications involve technical, legal and procedural requirements. Professional assistance may include patentability assessment, prior-art search, drafting, claim drafting, filing, examination response, hearing assistance, renewal monitoring and licensing support. It cannot guarantee patent grant or permanent protection.
