In this blogpost, Harsha Jeswani, Student, National Law Institute University, Bhopal analysis the Norvatis case.


The judgment rendered by the Supreme Court in the case of Novartis AG (“Novartis”) v. Union of India is one of the landmark judgements of the Supreme Court. The decision came as a relief for millions of people around the world to have access to medicines at a low cost, thus preventing the pharmaceutical industries from “evergreening” their patents.  While the judgement is seen as a means to ensure the availability of life-saving drugs at an affordable price to people in India and elsewhere, at the same time the decision defined the scope of Section 3(d) of the Indian Patents (Amendment) Act, 2005. In the said matter, the Supreme Court refused to grant a patent to a drug of Novartis AG on the basis that the said drug did not involve an invention which is capable of being patentable under Indian law.


In 1997, Novartis, a Swiss based pharmaceutical giant filed an application to grant patent to an anticancer drug Glivec which is used to treat Chronic Myeloid Leukemia (CML) and Gastrointestinal Stromal Tumours (GIST) on the basis that it invented the beta crystalline salt form (imatinib mesylate) of the free base, imatinib..  It is a critical drug which is patented in about 35 countries of the world.

However during those days, India did not grant patent to pharmaceutical products and agrochemical products.  It was in the year 2005 in India; the drug products became the subject of patent in compliance with the TRIPS agreement. India thereon revised its patent law and started granting patents on pharmaceutical drugs. Subsequently in 2006, the Madras Patent Office refused the patent application of Novartis for its drug Glivec stating that the said drug did not exhibit any major changes in therapeutic effectiveness over its pre-existing form, which was already patented outside India. The said decision was based on Section 3(d) of the Indian Patents (Amendment) Act, 2005 which provides  a known substance can only be patented if its new forms exhibit “enhanced efficacy”. The Patent Office did not find any enhanced efficacy in the drug Glivec and, therefore, considered it incapable of patentable under Section 3(d) of 2005 Act.

In May 2006, Novartis filed two writ petitions under Article 226 of the Indian Constitution before the High Court of Madras – one appealing against the order of Madras Patent Office rejecting its patent request and the other contesting that Section 3(d) of the Indian Patents Act is not in compliance with TRIPS and is vague, arbitrary and violative of Article 14 of the Constitution.

The Madras High Court refused the Writ Petitions of Novartis holding that it did not have jurisdiction to determine whether a domestic law is in contrary to international treaty, so it  cannot decide whether Section 3(d) is in compliance with TRIPS.  As far as Section 3(d) is considered, the objective of the Amending Act was to prevent evergreening and to make easy  the access to life-saving drugs to the citizens. Therefore, it cannot be considered to be vague and arbitrary.

The new phase of litigation started in Intellectual Property Appellate Board, which is an appellate body of  patent controller. IPAB considered the beta-crystalline form of imatinib mesylate as new and an inventive step but refused to grant a patent to the drug of Novartis since it was hit by Section 3(d) of the Act. Novartis challenged the said order by filing Special Leave Petition before the Supreme Court.


The main issues that came before the Supreme Court were-

  1. Whether the invention is in consistent with Section 3(d) of the patent act?
  2. Interpretation of Section 3(d) of the patent act?
  3. Whether the invention qualifies for the test of novelty and inventive for the alleged product?

The Supreme Court adopted the following approach-

  1. Court observed that the product was one of the new forms of the substance and not the whole substance. It has always existed in the original amorphous form. The product thus has to qualify the test laid down in Section 3(d) of the Patent Act.
  2. The Section clearly specifies that a new form of the substance in not patentable under Indian law unless it enhances its “known efficacy”.
  3. Novartis contended that the physico-chemical properties of the polymorph form of the imatinib molecule, i.e. better flow properties, better thermodynamic stability and lower hygroscopicity, resulted in improved efficacy and hence is patentable under Indian law.

The Apex Court rejected this contention stating that in the case of medicines, efficacy means “therapeutic efficacy” and these properties while they may be beneficial to some patients do not meet this standard. The Supreme Court also held that patent applicants must prove the increase in therapeutic efficacy based on research data in vivo in animals.

The Supreme Court held that the true intention to enact section 3(d) was to prevent the concept of evergreening and thus if the invention does not fulfil the test of Section 3(d), it cannot be granted a patent. The court further specified that this case should not be interpreted to mean that Section 3(d) bars all incremental inventions. It is with regard to the field of medicine especially in cases of life-saving drugs, a great acre and caution needs to be taken so as to protect the right to life of the masses.


The SC judgement comes as a huge relief for those people who can’t afford the lifesaving drugs manufactured by these big pharma giants. These companies who have already made billions of dollars prevent people from purchasing the drugs at low price thus endangering the very life of the poor people by acquiring patents over their drugs. The importance of patent cannot be denied to prevent a new invention provided such invention is available to all the individuals at a reasonable rate. On the contrary, companies like Novartis are putting the life of these poor people at stake by obtaining a monopoly over its drugs. However, the Supreme Court in its judgement made clear that India is a developing country and the availability of medicines at a cheap price is necessary for the lives of 1 billion people. The Supreme Court is thus justified in its decision thereby prohibiting the liberal approach in granting patents and granting patents only to genuine inventions as against frivolous inventions.
