Topic 53 Rights Patentee
Topic 53 — Rights of the Patentee
A patent grants its holder a bundle of exclusive rights — the legal monopoly that constitutes the inventor's side of the patent bargain. Section 48 of the Patents Act 1970 codifies these rights in two distinct sub-clauses: Section 48(a) for product patents (the right to prevent third parties from making, using, offering for sale, selling or importing the product) and Section 48(b) for process patents (the right to prevent third parties from using the process or using/selling/importing products directly obtained from the process). Section 53 specifies the 20-year term. Sections 49-52 govern licensing, registration, and assignment of patent rights. Section 50 specifies the rights of co-owners. This topic walks through the entire bundle of patentee rights, the operational scope of each, the territorial and temporal limits, the leading cases, and the recent 2024-25 jurisprudence.
1. Architecture of Patentee Rights
Section | Subject |
|---|---|
Section 48 | Rights of patentees — exclusive rights to make, use, sell, import. |
Section 49 | Patent rights not infringed by use on foreign vessels/aircraft/vehicles. |
Section 50 | Rights of co-owners of patents. |
Section 51 | Power of Controller to give directions to co-owners. |
Section 52 | Grant of patent to true and first inventor where it has been obtained by another in fraud. |
Section 53 | Term of patent — 20 years from date of filing. |
2. Section 48 — The Bundle of Exclusive Rights
Section 48 — Rights of Patentees "Subject to the other provisions contained in this Act and the conditions specified in section 47, a patent granted under this Act shall confer upon the patentee— (a) where the subject matter of the patent is a product, the exclusive right to prevent third parties, who do not have his consent, from the act of making, using, offering for sale, selling or importing for those purposes that product in India; (b) where the subject matter of the patent is a process, the exclusive right to prevent third parties, who do not have his consent, from the act of using that process, and from the act of using, offering for sale, selling or importing for those purposes the product obtained directly by that process in India." |
A. Two Categories — Product and Process
48(a) PRODUCT PATENTS making/using/selling/importing | 48(b) PROCESS PATENTS using process + product directly obtained |
B. Five Operative Acts in Section 48(a)
For a product patent, the patentee can prevent third parties from:
- Making — manufacturing the patented product.
- Using — putting the product to use in any manner.
- Offering for sale — even before actual sale; soliciting buyers, listing for sale, advertising.
- Selling — transferring the product to a buyer.
- Importing — bringing the product into India for any of the above purposes.
C. Process Patent Coverage Under Section 48(b)
For a process patent, the patentee can prevent third parties from:
- Using the process — operating the patented method.
- Using/selling/importing products "directly obtained" by the process — products that are the immediate output of the patented process.
✅ "Directly obtained" — the operative limit The phrase "directly obtained" in Section 48(b) is critical. The patentee's rights extend only to products that are the immediate output of the patented process — not to derivatives, modifications, or downstream products. If the patented process produces compound X, and a third party uses X to make an unrelated compound Y by a different process, Y is NOT covered by the process patent. This narrow construction protects downstream innovation while preserving the patentee's core rights over the process and its immediate output. |
D. Pre-2005 vs Post-2005
Before the 2005 Amendment, India granted only process patents in pharmaceuticals, food, and chemicals. The 2005 Amendment introduced product patents in these fields. Today, both Section 48(a) and Section 48(b) apply across all technical fields. Existing pre-2005 process patents continue under their original scope.
3. Section 47 — Statutory Conditions on Patent Rights
Section 47 — Conditions "The grant of a patent under this Act shall be subject to the condition that— (1) any machine, apparatus or other article in respect of which the patent is granted or any article made by using a process in respect of which the patent is granted, may be imported or made by or on behalf of the Government for the purpose merely of its own use; (2) any process in respect of which the patent is granted may be used by or on behalf of the Government for the purpose merely of its own use; (3) any machine, apparatus or other article in respect of which the patent is granted or any article made by the use of the process in respect of which the patent is granted, may be made or used, and any process in respect of which the patent is granted may be used, by any person, for the purpose merely of experiment or research including the imparting of instructions to pupils; (4) in the case of a patent in respect of any medicine or drug, the medicine or drug may be imported by the Government for the purpose merely of its own use or for distribution in any dispensary, hospital or other medical institution maintained by or on behalf of the Government or any other dispensary, hospital or medical institution which the Central Government may, having regard to the public service that such dispensary, hospital or medical institution renders, specify in this behalf by notification in the Official Gazette." |
A. Four Statutory Carve-Outs
1 GOVERNMENT USE product/process for own use | 2 RESEARCH USE experiment, research, teaching | 3 GOVT MEDICINE public hospitals/dispensaries |
✅ Section 47(3) — research exemption Section 47(3) provides a research exemption — anyone can use the patented invention for "experiment or research including the imparting of instructions to pupils". This is the Indian equivalent of the "experimental use" defence in other jurisdictions. The exemption covers: · Bona fide research aimed at understanding or improving the invention. · Educational use in teaching institutions. · Bolar-type pre-marketing research (preparing generic versions for post-expiry launch — though not separately codified, generally understood to be covered). Commercial use disguised as research is NOT protected. |
4. Section 53 — Term of Patent
Section 53 — Term of Patent "(1) Subject to the provisions of this Act, the term of every patent granted, after the commencement of the Patents (Amendment) Act, 2002, and the term of every patent which has not expired and has not ceased to have effect, on the date of such commencement, shall be twenty years from the date of filing of the application for the patent. (2) A patent shall cease to have effect notwithstanding anything therein or in this Act on the expiration of the period prescribed for the payment of any renewal fee, if that fee is not paid within the prescribed period or within such extended period as may be prescribed." |
A. The 20-Year Uniform Term
Pre-2002 Amendment, the Patents Act distinguished:
- 14-year term for general inventions.
- 7 years from filing OR 5 years from sealing (whichever shorter) for pharmaceutical/food/insecticide processes.
The 2002 Amendment unified the term at 20 years from the date of filing (the international standard set by TRIPS Article 33). The 2005 Amendment confirmed this for product patents in pharmaceuticals.
B. From "Date of Filing"
The 20-year term runs from the date of filing of the patent application — NOT from the date of grant. This means:
- Examination delays effectively reduce the patent's effective monopoly period.
- Strategic timing of filing matters — early filing maximises the monopoly period.
- Pre-grant disclosures by competitors can erode the practical value of the patent.
C. Renewal Fees
Section 53(2) makes the 20-year term contingent on payment of annual renewal fees. The fee schedule increases progressively:
Year of patent | Renewal fee (natural person/startup/small entity) | Renewal fee (other) |
|---|---|---|
1-2 | Not separately payable; covered by filing fee | Not separately payable |
3 | ₹800 | ₹4,000 |
4-5 | ₹1,000 each year | ₹4,000 each year |
6-9 | ₹2,000 each year | ₹8,000 each year |
10-15 | ₹4,000 each year | ₹16,000 each year |
16-20 | ₹8,000 each year | ₹32,000 each year |
✅ Restoration under Section 60 If renewal fees are not paid, the patent ceases to have effect — but Section 60 allows restoration within 18 months of cessation if the patentee can prove that the failure was unintentional. Restoration is at the Controller's discretion and may be subject to terms protecting third parties who acted on the assumption that the patent had lapsed. |
5. Section 50 — Co-Owners of Patents
Section 50 "(1) Where a patent is granted to two or more persons, each of those persons shall, unless an agreement to the contrary is in force, be entitled to an equal undivided share in the patent. (2) Subject to the provisions contained in this section and in section 51, where two or more persons are registered as grantee or proprietor of a patent, then, unless an agreement to the contrary is in force, each of those persons shall be entitled, by himself or his agents, to make, use, exercise and sell the patented invention for his own benefit without accounting to the other person or persons. (3) Subject to the provisions contained in this section and in section 51 and to any agreement for the time being in force, where two or more persons are registered as grantee or proprietor of a patent, then, a licence under the patent shall not be granted and a share in the patent shall not be assigned by one of such persons except with the consent of the other person or persons." |
A. Default Rule — Equal Undivided Share
Co-owners hold equal undivided shares unless otherwise agreed. Each co-owner can independently:
- Make, use, sell the patented invention.
- Earn profits without accounting to the others.
- Sue for infringement (with the others joined as parties).
B. Restrictions on Licensing and Assignment
Section 50(3) restricts what a single co-owner can do:
- Cannot grant a licence without consent of the others.
- Cannot assign the share without consent of the others.
Section 51 empowers the Controller to give directions resolving disputes between co-owners — for example, when one co-owner refuses unreasonably to consent.
6. Section 49 — Foreign Vessels Exemption
Section 49 "(1) Where a vessel or aircraft registered in a foreign country or a land vehicle owned by a person ordinarily resident in such country comes into India (including the territorial waters thereof) temporarily or accidentally only, the rights conferred by a patent for an invention shall not be deemed to be infringed by the use of the invention— (a) in the body of the vessel or in the machinery, tackle, apparatus or other accessories thereof, so far as the invention is used on board the vessel and for its actual needs only; or (b) in the construction or working of the aircraft or land vehicle or of the accessories thereof, as the case may be." |
Section 49 implements Article 5ter of the Paris Convention — patents do not extend to foreign vessels, aircraft, and land vehicles temporarily in Indian territory. This protects international commerce and travel. The exemption is narrow:
- Temporary or accidental presence only — permanent installation does not qualify.
- Use for the vessel's/aircraft's/vehicle's own needs — not for sale or distribution in India.
- Foreign registration or foreign-resident ownership.
7. Territorial Scope of Patent Rights
A. Strictly Territorial
Section 48 expressly limits the patentee's rights to acts "in India". Indian patents do not provide protection abroad — the patentee must obtain corresponding patents in each country where protection is sought. This territoriality follows from:
- Section 48 textual limit ("in India").
- Article 4bis Paris Convention — independence of patents.
- Article 27 TRIPS — minimum substantive standards but national grant.
B. Use Across Borders
What if a process is partially performed in India and partially abroad? What if a product is imported in components and assembled in India? Indian courts apply a "substantial use" test — if the substantial commercial activity occurs in India, the patent is infringed even if some steps occur abroad.
8. Practical Considerations for Patent Holders
✅ Twelve points for exercising patent rights effectively Calendar all renewal fee deadlines — failure to pay forfeits the patent (Section 53(2)). For pharmaceutical product patents, monitor for generic launches; file Form 27 working statements annually under Section 146. For process patents, monitor for products that may be "directly obtained" from the patented process — that is the operative scope. For multi-jurisdictional patents, maintain consistent claim language to support international harmonisation. Use Section 48(a) "offering for sale" to obtain pre-launch injunctions against competitors planning generic launch. For research-use claims by competitors, scrutinise for commercial purpose — Section 47(3) is narrow. For co-owned patents, document all use arrangements; obtain clear consent for licensing/assignment under Section 50(3). For government use claims, monitor compliance with Section 47(1) and Section 47(4) — government use is not unconditionally free. For territorial coverage, file in all major manufacturing and consumption markets — patent rights are strictly territorial. For the practical "monopoly period", account for examination delays — file early. For Section 60 restoration, maintain robust records of unintentional non-payment for restoration applications. For Section 49 exemptions, document the foreign-registration and "temporary or accidental" presence — exemption is narrow. |
