Every smartphone, life-saving drug, and clever gadget you use started as an idea in someone’s mind. But ideas are fragile. Without legal protection, an inventor could spend years and crores of rupees developing something new, only to watch a competitor copy it overnight. This is exactly the problem the Patents Act, 1970 was designed to solve. It is the backbone of India’s patent system, granting inventors exclusive rights over their creations for a fixed period in exchange for sharing those inventions with the public. Let us break down how this landmark law works, where it came from, and why it matters so much for innovation.

History and evolution of the Patents Act
India’s tryst with patent law goes back much further than 1970. The system began in 1856 with the enactment of Act VI, which offered a 14-year protection period. Over the following decades these early laws were revised and consolidated several times, eventually being replaced by the Indian Patents and Designs Act, 1911, a colonial statute modelled on British law.
By the time India gained independence, this 1911 framework was seen as inadequate for a developing nation. It served the interests of foreign companies far more than it encouraged local invention. To examine the issue, the government appointed the Justice N. Rajagopala Ayyangar Committee in 1957 to recommend a complete revision. The committee’s report shaped what would become the modern statute, and the Patents Act, 1970 was finally enacted, coming into force on 20th April 1972.
A law built for a developing economy
The 1970 Act made a deliberate and important choice. For sensitive sectors like food, medicines, and chemicals, it allowed only process patents rather than product patents. In simple terms, you could patent a specific method of making a drug, but not the drug itself. This was designed to keep essential goods like medicines affordable and accessible, allowing the domestic pharmaceutical industry to flourish by producing low-cost generic versions of drugs.
The TRIPS amendments
This protective approach changed once India joined the World Trade Organization. As a signatory to the TRIPS Agreement (Trade-Related Aspects of Intellectual Property Rights), India was obligated to bring its patent law in line with global standards. This happened through three key amendments. The 1999 amendment introduced a “mailbox” system, letting companies file pharmaceutical product patent applications that would only be granted later. The 2002 amendment standardised the patent term at 20 years for all categories of invention. Finally, the 2005 amendment expanded product patent protection to all fields of technology, including drugs and chemicals, while introducing provisions for compulsory licensing and pre-grant and post-grant opposition.
The Act continues to evolve. More recently, the Jan Vishwas (Amendment of Provisions) Act, 2023 amended the Patents Act and came into force on 1st August 2024, focusing on decriminalising minor procedural lapses and easing compliance.
Key features of the Patents Act
At its core, a patent is a bargain between the inventor and society. The inventor gets exclusive rights to make, use, sell, or import the invention for a limited time, and in return, the inventor publicly discloses how the invention works so that knowledge eventually enters the public domain. To qualify for this protection, an invention must clear three fundamental tests.
The three pillars of patentability
Under the Act, an invention must satisfy novelty (it must be new), inventive step (it must not be obvious to a person skilled in the relevant field), and industrial applicability (it must be capable of being used in an industry). If even one of these is missing, the application will fail. A new but obvious tweak to an existing product, for example, will not pass the inventive step test.
What cannot be patented
Interestingly, the Act does not provide a list of what can be patented. Instead, Section 3 lists subject matter that does not qualify as an invention and is therefore excluded from patent protection. These exclusions act as a gatekeeper to ensure patents reward genuine technical contributions. Some important non-patentable categories include:
- Frivolous inventions: Things that go against well-established natural laws, such as a perpetual motion machine that claims to defy the laws of thermodynamics.
- Inventions against public order or morality: Anything whose use would be contrary to public order or cause serious harm to humans, animals, plants, or the environment.
- Mere discoveries: Finding a scientific principle or a substance that already exists in nature is a discovery, not an invention.
- Creative and abstract works: Literary, dramatic, musical, or artistic works are protected by copyright, not patents, as are mere schemes, rules, or methods for performing mental acts or playing games.
- Agricultural methods and traditional knowledge: Methods of agriculture or horticulture and inventions that are essentially traditional knowledge are excluded.
Section 3(d): the anti-evergreening shield
One provision deserves special mention. Section 3(d) prevents companies from getting fresh patents on minor modifications of known substances. It disallows patent protection for the mere discovery of a new form of a known substance unless it shows a significant enhancement in efficacy. This stops a practice called “evergreening,” where firms try to extend monopolies by making trivial changes. The provision famously came into focus in the Novartis case, where the Supreme Court rejected a patent application for a modified form of the cancer drug Glivec, protecting affordable access to medicine.
Patent filing process
Securing a patent is a structured journey that typically takes several years. The system is administered by the Controller General of Patents, Designs and Trademarks through four patent offices located in Delhi, Mumbai, Chennai, and Kolkata, with your jurisdiction depending on where you live or work.
Step 1: Prior art search and drafting
Before filing anything, the sensible first step is a prior art search. This means searching existing patents and published material to check whether the invention is truly new. If something similar already exists in the public domain, the application is likely to be rejected later. Once novelty looks promising, the inventor prepares a specification describing the invention.
Step 2: Provisional or complete specification
An applicant can file in one of two ways. A provisional specification secures an early priority date when the invention is still being refined. A complete specification is filed when the invention is fully developed and includes detailed claims defining the scope of protection. Importantly, if a provisional application is filed, the complete specification must be submitted within 12 months, or the application is treated as abandoned. Filing is done electronically through the patent office portal using the prescribed forms.
Step 3: Publication
After filing, the application is published in the official patent journal after 18 months from the filing or priority date. This makes the invention part of the public record. Applicants in a hurry can request early publication by filing Form 9. Significantly, publication gives the applicant certain provisional rights, although these can only be enforced once the patent is actually granted.
Step 4: Request for examination
India follows a deferred examination system, meaning the patent office does not examine an application automatically. The applicant must file a separate request for examination. For applications filed on or after 15 March 2024, this request must be filed within 31 months of the priority date, reduced from the earlier 48-month window.
Step 5: Examination report and grant
The examiner then issues a First Examination Report (FER) listing any objections. The applicant must respond to these objections, usually within six months, with possible extensions. Once the controller is satisfied that all requirements are met, the patent is granted and published in the journal. From start to finish, the process typically takes between three and five years.
Patent infringement and remedies
Getting a patent is only half the story. A patent gives you the right to stop others from exploiting your invention, but that right is meaningless unless you can enforce it. Patent infringement occurs when someone makes, uses, sells, or imports a patented invention without the patent holder’s permission. Section 48 confers these exclusive rights, while Sections 104 to 111 deal with infringement suits and jurisdiction.
Where to file and the remedies available
An infringement suit can be filed in a district court or commercial court that has jurisdiction. The central provision for relief is Section 108. It allows a court to grant an injunction along with, at the plaintiff’s option, either damages or an account of profits. The two main categories of relief work as follows:
- Injunction: A court order directing the infringer to stop the infringing activity. An interim or temporary injunction can be granted early in the case to preserve the status quo, while a permanent injunction is granted at the end of the trial.
- Damages or account of profits: The patent holder can recover compensation for losses suffered, or alternatively claim the profits the infringer earned. Crucially, these two remedies are alternatives, not cumulative – a patentee cannot claim both.
Beyond these, the court can also order that infringing goods and the implements used to make them be seized, forfeited, or destroyed without compensation. There is one notable protection for honest defendants: damages or an account of profits will not be granted against someone who proves the infringement was innocent, meaning they had no reasonable grounds to believe the patent existed.
Role of the Patents Act in research and development
Why does any of this matter beyond the courtroom? The answer lies in how patents fuel research and development (R&D). R&D is expensive and risky. A company might spend years and enormous sums chasing a breakthrough that may never pay off. The promise of a temporary monopoly is what makes this gamble worthwhile.
The incentive to invent
Under the Act, Section 53 grants a patent a maximum term of 20 years from the date of filing, aligning India with the TRIPS standard followed worldwide. During this window, the inventor can commercialise the invention exclusively and recover development costs. Once the term ends and renewal fees stop, the invention falls into the public domain for anyone to use freely. This trade-off – temporary exclusivity in exchange for eventual public access – is the engine that rewards innovation while ensuring knowledge is not locked away forever.
Disclosure builds on knowledge
Patents do more than protect individuals. Because every patent must publicly disclose how the invention works, it adds to a shared pool of technical knowledge that other researchers can study and build upon. This prevents wasteful duplication and accelerates collective progress.
Measurable economic impact
The shift to stronger patent protection has had real effects on Indian industry. A study of India’s move to a TRIPS-compliant regime found that firms more exposed to stronger patent protection increased their patenting activity and their R&D expenditure. In a knowledge-driven economy, businesses that invest in patents often gain greater technological leadership and stronger brand value. The patent system thus connects directly to national initiatives that aim to make India a hub of innovation and entrepreneurship.
Yet the Act maintains a careful balance. Provisions like compulsory licensing and Section 3(d) ensure that this drive for innovation does not come at the cost of public welfare, especially when it comes to access to essential medicines. This balancing act between private reward and public good is what makes the Patents Act, 1970 such a thoughtfully constructed piece of legislation.
What do you think? Does India’s emphasis on safeguarding access to affordable medicines through provisions like Section 3(d) strike the right balance, or does it risk discouraging pharmaceutical companies from investing in costly drug research? And as artificial intelligence begins to generate inventions of its own, how should a law written in 1970 decide who – if anyone – deserves to hold the patent?
