MNCs to Challenge MNC Patents in India: Boon for Patients?

Close on the heels of a reasonably successful patent challenge by the German pharma Multinational Corporation (MNC) Fresenius Kabi for the breast cancer drug Tykerb of GlaxoSmithKline (GSK) in India, another MNC Mylan, with its headquarter in the United states, has explicitly expressed its plan to challenge frivolous and weak patents of MNCs, in conformance to the Indian Patents Act, to provide less expensive generic drugs to patients.

This is indeed another interesting development, which could possibly culminate into robust, cleverly crafted and fiercely competitive business strategies of many other MNCs, revolving around patent challenges in India, for business excellence in the country.

Mylan develops new products in India:

Mylan is now reportedly working with the local Indian player Biocon to develop a strong new product pipeline, which would include a portfolio of biosimilar drugs. The advanced breast cancer drug Trastuzumab (Herceptin) of Roche is just one of many in the list. Mylan has also expressed its intent to market ‘Herceptin’ at a price, which will be affordable to many more cancer patients of India.

It is worth mentioning that some other domestic Indian companies like, Reliance Life Sciences and BDR Pharma are reportedly working on generic Trastuzumab (Herceptin), besides some South Korean bio-pharma players.

Mylan has also inked an agreement with Biocon to develop and market an insulin drug derived from the global major Sanofi’s expensive patented product Lantus.

All these developments apparently augur well for India.

Weak patent?…Recapitulating Herceptin saga in india:

Though Roche decided to discontinue its patent rights for Herceptin in India, it reportedly lost this patent earlier in Europe. This vindicates the views of experts that Herceptin patent was weak, as it would probably not be able to clear the litmus test of a stringent patent scrutiny. The report, therefore, argues that core reason for withdrawal of Herceptin patent in India by Roche cannot be attributed, even remotely, to the ‘weak IP ecosystem’ in India.

To extend the patent right for Herceptin, in early September 2013, Roche reportedly announced that the European Commission has approved a new formulation of its breast cancer drug Herceptin, which allows the medicine to be administered more quickly.

A tough market, yet difficult to ignore:

For global innovator pharma majors, India still remains a tough market to crack, despite strong overseas political pressures of various types, intense collective and individual lobbying efforts and deployment of expensive global ‘Public Relations’ firms working in full steam.

Their strong success factors of the yesteryears in this area, which worked so well across the world, are getting mostly negated by the ‘evolving patient friendly IP laws’ of the emerging economies.

Considering the vast business potential of the pharmaceutical market of 1.2 billion people in India, it is now envisaged by many, more like-minded MNCs will gradually jump into this fray with similar intent of patent challenges in conformance with the Indian Patents Act 2005.

If this scenario assumes a cascading effect on a broader canvas, ultimate beneficiary will be the ailing patients, having much greater access to more affordable newer drugs for many dreaded diseases, like cancer.

Other countries too tightening up the patent laws:

To provide less-expensive generic drugs to patients, other countries also have started following India to leash astronomical prices for new drugs, especially for life threatening and intensely debilitating ailments. China has reportedly strengthened its compulsory licensing provisions already for dealing with costly drugs, paving the way to force entry of generic drugs in the Chinese market well before patent expiry.

In 2012, Indian Patent Office, in a path breaking decision granted Compulsory License (CL) to a local company, Natco Pharma, to manufacture the patented kidney-cancer drug, Nexavar of Bayer reportedly at a cost of Rs. 8,800 (around US$ 176) for a month’s therapy of 120 capsule against Bayer’s price of Rs. 280,000 (around US$ 5,600) for the same.

This is the first-ever case of CL granted in India thus far to make life saving drugs affordable to patients.

On September 3, 2012, the Indonesian government took the unprecedented step of overriding the patents on seven HIV and hepatitis treatments, citing urgent need to improve patient access. These drugs were reportedly beyond the reach of most of the patients in Indonesia.

Thailand has also used this provision more than once, and countries like, Brazil has reportedly threatened quite often for invoking CL during price negotiations of such drugs with global pharma majors.

Winds of Change in South Africa:

Now South Africa has also exhibited its firm intent to have a tight leash on the grant of pharmaceutical patents of all types.

A recent report indicates that the Department of Trade and Industry (DTI) of the Government of South Africa is calling for comments on its proposed ‘National Policy on Intellectual Property’ by October 4, 2013, which if implemented, would significantly curb patent evergreening and expand production of generics.

The same report mentions that at present, South Africa does not examine patent applications. Instead, the system allows pharmaceutical companies to obtain multiple patents on the same drug, even for inventions, which do not fall under the country’s definition of innovation. This allows the pharma players to extend their respective patent lives, blocking competition and charging exorbitant prices.

The report also points out, while in 2008, South Africa granted 2,442 pharmaceutical patents, Brazil approved only 278 in the 5 years between 2003 and 2008.

Patents revoked in India:

Since November 2010 following 8 MNC patents have been revoked in India after respective patent challenges:

  • Combigan and Ganfort of Allergan (for specified eye conditions)
  • Tykerb of GSK (for breast cancer)
  • Sutent of Pfizer (for liver and kidney cancer)
  • Pegasys of Roche (for hepatitis C)
  • Iressa of AstraZeneca (Anti-cancer)
  • Anti-asthma FDC aerosol suspension of Merck & Co (Anti-asthma)
  • Dulera of Novartis (Anti-asthma)

China and Brazil revoked patents

In August 2013, just about a year after China introduced the country’s amended patent law, its State Intellectual Property Office (SIPO) has reportedly revoked the patent on HIV/AIDS and hepatitis B drug – Viread (tenofovir disoproxil fumarate) of Gilead Science Inc.

Aurisco, the largest manufacturer of Active Pharmaceutical Ingredients (APIs) in China, challenged this patent. The ground of patent revocation was that the drug lacked novelty and was not entitled to protection.

In 2008 Brazil also declared the patent of tenofovir invalid. It is worth mentioning that tenofovir of Gilead is the third-best-selling drug of the company, clocking sales of US$ 849 million in 2012.

Top 10 ‘jaw-dropping’ most expensive medicines of the world:

No. Name Disease Price US$ /Year
1. ACTH Infantile spasm 13,800,00
2. Elaprase Hunter Syndrome 657,000
3. Soliris Paroxysmal nocturnal hemoglobinuria 409,500
4. Nagalazyme Maroteaux-Lamy Syndrome 375,000

9. Ceredase / Cerezyme Gaucher Disease 200,000
10. Fabrazyme Fabry Disease 200,000

(Source: Medical Billing & Coding, February 6, 2012)

The good news is, protests against such ‘immoral and obscene pricing’ have started mounting, which are expected to have a snow-balling effect in the years ahead.

Mounting global protests:

Probably due to this reason, drugs used for the treatment of rare diseases are being reported as ‘hot properties for drug manufacturers’, all over the world.

The above report highlighted a changing and evolving scenario in this area.

In 2013, the Dutch Government had cut the prices of new enzyme-replacement therapies, which costs as high as US$ 909,000. Similarly, Ireland has reduced significantly the cost of a cystic fibrosis drug, and the U.K. rejected a recommendation to expand the use of a drug for blood disorders due to high costs.

Soon, the United States is also expected to join the initiative to reduce high prices of orphan drugs as both the government and private insurers increasingly come under the cost containment pressure.

Emerging markets – the Eldorado:

Competition within MNCs is expected to be even more fierce in the coming years as the developed markets continue to slow down, as follows, due to various reasons:

This compelling scenario is prompting a change in the dynamics of competition within  MNCs in the emerging pharmaceutical markets. The intents of Fresenius Kabi and Mylan, as enunciated above, I reckon, are just very early signals of this challenge of change.

All these would probably help turning the tide in favor of a seemingly win-win solution to bring down the prices of patented medicines at an affordable level, improving their access to vast majority of patients in the world.

Scope for more patent challenges in India:

Quoting a study, a recent media report highlighted that only 3% of the patent applications filed in India since 2006 were challenged. The study concluded:

“This demonstrates that given the various resource constraints faced by the Indian patent office, one can never really be sure of the patent quality unless the patent is challenged.”

Therefore, this process is expected to gain momentum in the years ahead as more MNCs join the fray of patent challenges, though driven primarily by business interests, but nevertheless, would benefit the patients, in the long run.

Further, as indicated in my previous columns, study indicates that 86 pharmaceutical patents granted by the IPO post 2005 are not breakthrough inventions but only minor variations of existing pharmaceutical products and demanded re-examination of them.

Since, most of the above patents have not been challenged, as yet, the quality of these patents cannot be ascertained beyond any reasonable doubt, as we discuss today. If challenged, some experts envisage, these patents may not be able to stand the scrutiny of section 3(d) of the Indian Patents Act.

In that sense, if the pharma MNCs with deep pockets, challenge these patents, there stands a good chance of making generic equivalents of those products at affordable prices for the Indian patients.

However, considering different degree and elements of market entry barriers, it appears, most of the patent challenges in India by the MNCs would probably be for biologics, as compared to small molecule chemicals.

Flow of newer drugs in the Indian market is now irreversible:

Taking stock of the emerging scenario, it appears, India will continue to see newer drugs coming into the market at a lower price in the years ahead, come what may. This flow seems to be unstoppable due to the following reasons:

  • Stricter implementation of Section (3d) of the Patents Act in India will ensure that NCEs/NMEs not conforming to this act will not be granted patents. In that case, those products will be open to generic copying by all, in India. Thus, in the absence of a market monopoly situation and fuelled by intense price competition, the patients will have access to those newer drugs.
  • More patent challenges of already granted patents could lead to revocation of more number of patents paving the way for entry of their generic equivalents.
  • If any MNC decides not to launch a new product in India having obtained its patent from the IPO, after three years, as per the statute, the same product becomes a candidate for CL in the country.
  • If any patented new product is launched without ‘reasonably affordable price’, again as per statute, the possibility of applications for CL coming to the IPO from the local players will loom large.

Hence, considering all these points, it appears, if the new products do not conform to the Indian Patents Act and are not launched with responsible pricing, the possibility of their generic entry at much lower prices is almost inevitable.

Conclusion: 

Legal battle is expensive, even in India, and patent challenges are perhaps more expensive. All those new products, which are not patentable in India or may otherwise be challenged against other statutes of the Patents Act, will carry risks of getting caught in protracted litigations or generic competition.

MNCs with deep pockets coming forward with such intent, though may be based purely on their business interest in India, would ultimately offer spin-off benefits of affordable pricing, especially, to the patients suffering from life threatening and fast debilitating illnesses like, cancer.

That said, do all these developments unravel yet another way to improve access to newer medicines in India, signaling a boon for patients?

India, China Revoke Four Pharma Patents in A Fortnight: A Double Whammy for MNCs?

Revocation of four pharma patents by India and China within a fortnight has raised many eyebrows, yet again, across the globe. In this short period, India has revoked three patents and China one.

While this quick development is probably a double whammy for the Multinational Corporations (MNCs) operating in both the countries, a future trend could possibly emerge by analyzing and connecting the evolving dots.

On August 8, 2013, a judicial body, the Intellectual Property Apellate Board (IPAB) of India reportedly revoked two patents of Allergan Inc on Combigan and Ganfort, both are Fixed Dose Combination (FDC) drugs of known molecules, used in the treatment of specified eye conditions. Local pharmaceutical player Ajantha Pharma had challenged these patents granted earlier to Allergan Inc. by the Indian Patent Office (IPO), alleging that the patents were obtained on false representation, the compositions were obvious ones, mere admixture of two pharmaceutical substances and not inventions.

IPAB in its order, while revoking the patent, has also said:

  • “The revocation of the patent was sought on various grounds that the patent was obtained on a false suggestion or representation, that it is not an invention, that it is obvious and does not sufficiently disclose and that the Section 8 of the Patents Act, 1970 was violated.”
  • The “respondents (Allergan Inc) have incorrectly deciphered enhancement in therapeutic efficacy as reduction in interocular pressure comparable to serial application.”
  • “The respondent has not shown that it had complied with the Section 8 of Patents Act, 1970.”

Though Allergan claimed to have achieved enhanced efficacy with reduced side effects for these FDCs, the IPAB did not find the claims justifiable. Interestingly, Ajantha’s product reportedly is much less expensive too. As compared to Allergan’s Ganfort drops (3 ml) costing about Rs 580, Ajanta’s equivalent formulation costs just Rs 131.

The other pharma patent revocation of the fortnight:

On July 27, 2013, IPAB revoked yet another patent granted earlier to GlaxoSmithKline (GSK)’s Lapatinib ditosylate salt of its breast cancer drug Tykerb, while upholding the patent on the original API, Lapatinib. IPAB in its order has stated that the ditosylate salt version of Lapatinib is not patentable as per patentability criteria of the Indian Patents Act.

Experts believe, with these decisions, the Indian legal system has clearly demonstrated that despite intense anger, pressure and protests mainly from the United States and Europe, to dilute public health interest related safeguards enshrined in the current Indian patent regime, the rule of law still prevails in the country for IP disputes.

Tykerb decision of IPAB follows the landmark judgment of the Supreme Court of India clarifying patentability criteria for incremental innovations.

An interesting precedent set:

In case of Tykerb of GSK, unlike other occasions, for the first time one MNC has challenged the patent of another MNC in India, instead of domestic companies doing so. The German drug manufacturer, Fresenius Kabi, instead of criticizing Indian IP law like other MNCs, had challenged the British drug maker GSK’s patent on the patentability criteria as provided in the Indian Patent Law and obtained a favorable decision from the IPAB against one of their two patent challenges on Tykerb.

A different case, yet worth mentioning:

Earlier, in late 2012, Delhi High Court while recognizing the validity of Roche’s patent for Tarceva (erlotinib), ordered that Cipla’s generic equivalent of erlotinib has different molecular structures. Hence, Cipla has not infringed Roche’s patent.

The generic version of Cipla’s erlotinib is reportedly available at a price of Rs 1,600 against Roche’s price of Rs 4,800 for Tarceva. Though this is not a patent revocation, but an interesting case nevertheless.

Other patent revocations:

Besides the only Compulsory License (CL) issued, so far, by the IPO for Bayer’s Nexavar to Natco (Cost of a pack of 120 tablets of Natco generic is Rs.8,800 against Nexavar’s Rs. 280,000), such patent challenges are now taking place in India quite close on the heels of one another as follows:

Sutent (Pfizer): 

In this case, the patent for liver and kidney cancer drug of Pfizer – Sutent (Sunitinib), granted earlier by the IPO in 2007, was revoked by the IPAB in October 2012, after a post grant challenge by Cipla and Natco Pharma on the ground that the claimed ‘invention’ does not involve inventive steps.

However, on November 26, 2012 in a new twist to this case, the Supreme Court of India reportedly restored the patent for Sutent. Interestingly, at the same time the court removed the restraining order, which prevented Cipla from launching a copycat generic equivalent of Sunitinib.

The cost of 45 day’s treatment with Cipla generic is Rs. 50,000 against Rs. 196,000 of Sutent. (Source ET, April 7, 2013)

Pegasys (Roche):

Again, on November 2, 2012 the IPAB revoked the patent of Pegasys (Peginterferon alfa-2a) – the hepatitis C drug of the global pharmaceutical giant Roche. It is worth mentioning, Pegasys enjoys patent protection across the world.

Though Roche was granted a patent for Pegasys by IPO in 2006, this was subsequently contested by a post-grant challenge by the Indian pharma major – Wockhardt and the NGO Sankalp Rehabilitation Trust (SRT) on the ground that Pegasys is neither a ‘novel’ product nor did it demonstrate ‘inventiveness’ as required by the Patents Act of India.

It is worth noting, although the IPO had rejected the patent challenges by Wockhardt and SRT in 2009, the judicial body IPAB reversed IPO’s decision revoking the patent of Pegasys, costing Rs. 360,000 for a six month course of treatment for a patient.

Iressa (AstraZeneca):

On November 26, 2012, IPAB reportedly denied patent protection for AstraZeneca’s anti-cancer drug Iressa (Gefitinib) on the ground that the molecule lacked invention.

The report also states that AstraZeneca suffered its first setback on Gefitinib in June 2006, when the Indian generic company Natco Pharma opposed the initial patent application filed by the global major in a pre-grant opposition. Later on, another local company, GM Pharma, joined Natco in November 2006.

After accepting the pre-grant opposition by the two Indian companies, IPO in March 2007 rejected the patent application for Iressa Gefitinib citing ‘known prior use’ of the drug. AstraZeneca contested the order through a review petition, which was dismissed in May 2011.

Anti-asthma FDC aerosol suspension (Merck & Co):

Similar to Allergan case, on December 11, 2012 Indian Patent Office (IPO) reportedly revoked a patent granted to an anti-asthma FDC drug of Merck & Co on the ground of lack of invention, after the domestic pharma major Cipla Ltd challenged an earlier granted patent of this FDC drug.

This aerosol suspension combines three molecules: mometasone furoate, formoterol and heptaflouropropane.

A similar asthma treatment, Dulera, reportedly lost its Indian patent held by Novartis AG in 2010.

Patentability for ‘Incremental Innovations’ in India:

Patentability criteria for any ‘incremental innovation’ has been defined in the Section 3(d) of the Indian statute as follows:

“The mere discovery of a new form of a known substance which does not result in the enhancement of the known efficacy of that substance or the mere discovery of any new property or new use for a known substance or of the mere use of a known process, machine or apparatus unless such known process results in a new product or employs at least one new reactant.”

“Explanation: For the purposes of this clause, salts, esters, ethers, polymorphs, metabolites, pure form, particle size isomers, mixtures of isomers, complexes, combinations and other derivatives of known substance shall be considered to be the same substance, unless they differ significantly in properties with regard to efficacy.”

Indian Patents Act prevails: 

As is well known, way back in 2006, IPO refused to grant patent to the cancer drug Glivec of Novartis on the ground that the molecule is a mere modification of an existing substance known as Imatinib.

In that case, on April 1, 2013 the Supreme Court of India upheld the validity of Section 3(d), where the rules of the game for patentability of incremental pharmaceutical innovations, as captured in the Indian Patents Act 2005, were cast in stone.

Court did not disallow all incremental innovations:

Point 191 in page number 95 of the Glivec judgment very clearly states as follows:

“191. We have held that the subject product, the beta crystalline form of Imatinib Mesylate, does not qualify the test of Section 3(d) of the Act but that is not to say that Section 3(d) bars patent protection for all incremental inventions of chemical and pharmaceutical substances. It will be a grave mistake to read this judgment to mean that section 3(d) was amended with the intent to undo the fundamental change brought in the patent regime by deletion of section 5 from the Parent Act. That is not said in this judgment.”

Thus, it should not be highlighted unfairly by concerned constituents that all ‘incremental innovations’ are not patentable in India. The above judgment just says that Glivec is not patentable as per Section 3(d) of Indian Patents Act based on the data provided and the arguments of Novartis.

Only 3% of patents are challenged:

Quoting a study, a recent media report highlighted that only 3% of the patent applications filed in India since 2006 were challenged. The study concluded, “This demonstrates that given the various resource constraints faced by the Indian patent office, one can never really be sure of the patent quality unless the patent is challenged.”

Rejection by IPO under Section 3d is minimum – is that a key issue?

Another study done by Columbia University reportedly found that out of 214 patents filed in India last year, only 3 patents were rejected by IPO exclusively for failing to prove better efficacy, as required under Section 3d. Turning this finding on its head, would it be reasonable to ponder:

Could this be a key issue for so many patents failing to pass the acid test of judicial scrutiny when challenged?

Government has no role to play in IP disputes:

The proponents of ‘no change required in the Section 3(d)’ argue, patent challenge is a legal process all over the world, where the Government has hardly any role to play in resolving these disputes. The law should be allowed to take its own course for all disputes related to the Patents Act of the country, including Section 3(d).

They also opine that India must be allowed to follow the law of justice without casting aspersions on the knowledge and biases of the Indian judiciary by the vested interests.

That said, there is certainly an urgent need to add speed to this legal process by setting up ‘Fast-track Courts’ for resolving all Intellectual Property (IP) related disputes in a time bound manner.

Pharma patents granted in India:

As reported in the media, pharma MNCs have been granted over 1,000 patents since 2005. Moreover out of 4,036 patents granted in the past six years, 1,130 have been awarded to MNCs, like:

  • AstraZeneca 180 patents
  • Roche with 166 patents
  • Sanofi with 159 patents
  • Novartis with 147 patents

It is therefore understandable, as pharma MNCs have secured more number of pharma patents they are facing larger number of litigations at this point of time.

China and Brazil revoke patents:

Last week, just about a year after China introduced the country’s amended patent law, its State Intellectual Property Office (SIPO) has reportedly revoked the patent on HIV/AIDS and hepatitis B drug – Viread (tenofovir disoproxil fumarate) of Gilead Science Inc. Aurisco, the largest manufacturer of active pharmaceutical ingredients in China, challenged this patent. The ground of patent revocation was that the drug lacked novelty and was not entitled to protection.

In 2008 Brazil also declared the patent of tenofovir invalid. It is worth mentioning that tenofovir of Gilead is the third-best-selling drug of the company, clocking sales of US$ 849 million in 2012.

South Africa mulls new law to stop ‘Evergreening’:

Recently, the Department of Trade and Industry of South Africa has reportedly submitted to the South African Cabinet a draft Intellectual Property Policy with far-reaching changes to the country’s Intellectual Property Rights (IPR) for medicines in order to increase access to cheaper drugs by making it harder for companies to obtain and extend patents.

The draft includes a proposal to introduce a patent examination office to stop pharmaceutical companies from “evergreening” where companies take out new patents based on minor changes or new uses. 

Currently, South Africa uses a depository system, in which patent applications are granted without extensive scrutiny. Experts believe, “this system allows companies to file multiple patents on the same medicine and extend the life of their monopoly, keeping prices artificially high.”

Innovators Angry:

In this context, the following report recently captured the anger of the innovator companies and stated that the US drug giants are once again pushing for stronger patent protection in India:

“A coalition of U.S. lawmakers and business groups outlined concerns about Indian policies as a threat to American exports, jobs and innovation in a letter to President Barack Obama on June 18. Among the business groups were the Pharmaceutical Research and Manufacturers of America and the Biotechnology Industry Association. On June 14, the top Democrat and Republican on the Senate Finance Committee urged that Kerry raise trade concerns on his visit.”

Quoting US Chamber of Commerce’s Global Intellectual Property Center another report highlighted, “Recent policy and judicial decisions that invalidate intellectual property rights, which have been increasing in India, cast a daunting shadow over its otherwise promising business climate. From the revocation of patents to the staggering rates of piracy, India stands alone as an international outlier in IP policies. This trend is bad for investment, innovation and international trade.”

Does it benefit patients? 

In the paper titled ‘TRIPS, Pharmaceutical Patents and Access to Essential Medicines: Seattle, Doha and Beyond’, published in ‘Chicago Journal for International Law, Vol. 3(1), Spring 2002’, the author argues, though the reasons for the lack of access to essential medicines are manifold, there are many instances where high prices of drugs deny access to needed treatments for many patients. Prohibitive drug prices, in those cases, were the outcome of monopoly due to strong intellectual property protection.

The author adds, “The attempts of Governments in developing countries to bring down the prices of patented medicines have come under heavy pressure from industrialized countries and the multinational pharmaceutical industry”.

While the ‘Trade-Related Aspects of Intellectual Property Rights Agreement (TRIPS)’ of the World Trade Organization (WTO) sets out minimum standards for the patent protection for pharmaceuticals, it also offers adequate safeguards against negative impact of patent protection or its abuse in terms of extraordinary and unjustifiable drug pricing. The levels of these safeguards vary from country to country based on the socioeconomic and political requirements of a nation, as in India.

Patentability for ‘genuine innovations’:

A report on ‘Patentability of the incremental innovation’ indicates that the policy makers keeping the following points in mind formulated the Indian Patents Act 2005:

  • The strict standards of patentability as envisaged by TRIPS pose a challenge to India’s pharmaceutical industry, whose success depended on the ability to produce generic drugs at much cheaper prices than their patented equivalents.
  • A stringent patent system would severely curtail access to expensive life saving drugs to a large number of populations in India causing immense hardships to them.
  • Grant of a product patents should be restricted only to “genuine innovations” and those “incremental innovations” on existing medicines, which will be able to demonstrate significantly increased efficacy over the original drug.

Conclusion:

study by the ‘Indian Pharmaceutical Alliance (IPA)’ indicates that 86 pharmaceutical patents granted by the IPO post 2005 are not breakthrough inventions but only minor variations of existing pharmaceutical products and demanded re-examination of them.

Since, most of the above patents have not been challenged, as yet, the quality of these patents cannot be ascertained beyond any reasonable doubt, as we discuss today.

If the apprehension, as expressed above in the IPA study has any merit, right answers to the following questions, I reckon, would help charting out the future direction for the IP ecosystem of India:

  • Is there a theoretical possibility of revocation of all these 86 already granted product patents, if and when challenged in a court of law?
  • Is the current Patents Act of India pragmatic?
  • Does it reasonably benefit both the innovators and the Indian patients,  signifying a paradigm shift in the global IPR scenario?
  • Will it inspire other countries also to emulate similar IP system in the years ahead?
  • Will it then invite more intense ire of the global pharma innovator companies creating increasing  pressure on the Indian Government to amend the current Patents Act?
  • Being under continuous public scrutiny, would it be feasible for any Indian Government, now or in future, in the near or medium term, to amend the Indian Patents Act due to any amount of outside pressure?
  • And finally, is the Act then irreversible, at least, for quite some time from now?

Balancing IPR with Public Health Interest: Brickbats, Power Play and Bouquets

It is now a widely accepted dictum that Intellectual Property Rights (IPR), especially pharma patents, help fostering innovation and is critical in meeting unmet needs of the patients.

However, the moot question still remains, what type pharmaceutical invention, should deserve market exclusivity or monopoly with overall freedom in pricing, keeping larger public health interest in mind.

In line with this thinking, for quite sometime a raging global debate has brought to the fore that there are quite a large number of patents on drug variants that offer not very significant value to the patients over the mother molecules, yet as expensive, if not more than the original ones. In common parlance these types of inventions are considered as ‘trivial incremental innovations’ and described as attempts to ‘evergreening’ the patents.

The terminology ‘evergreeningusually ‘refers to a strategy employed by many pharmaceutical companies to extend their market monopoly by slightly changing the existing molecules and obtaining new patents to continue to enjoy market exclusivity and pricing freedom, which otherwise would not have been possible.

Path breaking or jaw-drooping ‘W-O-W’ types of innovations are not so many. Thus most of the patented drugs launched globally over the last several decades are indeed some sort of ‘me-too drugs’ and generally considered as ‘low hanging fruits’ of R&D, not being able to offer significantly greater value to patients than already exiting ones. Many of these drugs have also achieved blockbuster status for the concerned companies, backed by high voltage marketing over a reasonably long period of time. It is understandable, therefore, that from pure business perspective why serious global efforts are being made to push the same contentious system in India too.

Example of some of these molecules (not necessarily in the written order), are as follows:

  • Cemetidine – Ranitidine – Famotidine – Nizatidine – Roxatidine (to treat Acid-peptic disease)
  • Simvastatin – Pravastatin – Lovastatin – Pitavastatin – Atorvastatin – Fluvastatin – Rosuvastatin (to treat blood lipid disorder)
  • Captopril – Enalepril – Lisinopril – Fosinopril – Benzapril – Perindopril – Ramipiril – Quinalapril – Zofenopril (Anti-hypertensives)

However, pharmaceutical companies do argue that such ‘incremental innovations’ are the bedrock for growth of the pharmaceutical industry and are essential to continue to fund pharmaceutical research and development.

An interesting paper:

A paper titled, “Pharmaceutical Innovation, Incremental Patenting and Compulsory Licensing” by Carlos M. Correa argued as follows:

  • Despite decline in the discovery of New Chemical Entities (NCEs) for pharmaceutical use, there has been significant proliferation of patents on products and processes that cover minor, incremental innovations.
  • A study conducted in five developing countries – Argentina, Brazil, Colombia, India and South Africa has:
  1. Evidenced a significant proliferation of ‘ever-greening’ pharmaceutical patents that    can block generic competition and thereby limit patients’ access to medicines.
  2. Found that both the nature of pharmaceutical learning and innovation and the interest of public health are best served in a framework where rigorous standards of inventive step are used to grant patents.
  3. Suggested that with the application of well-defined patentability standards, governments could avoid spending the political capital necessary to grant and sustain compulsory licenses/government use.
  4. Commented, if patent applications were correctly scrutinized, there would be no need to have recourse to CL measures.

A remarkable similarity with the Indian Patents Act:

The findings of the above study have a striking similarity with the Indian Patents Act. As per this Act, to be eligible for grant of patents in India, the pharmaceutical products must pass the ‘two-step’ acid test of:

  • Following the inventive stepDefined under Section 2(ja) of the Patents Act as follows:

“Inventive step” means a feature of an invention that involves technical advance as compared to the existing knowledge or having economic significance or both and that makes the invention not obvious to a person skilled in the art.

  • Passing scrutiny of Section 3(d) of the law: It categorically states, inventions that are a mere “discovery” of a “new form” of a “known substance” and do not result in increased efficacy of that substance are not patentable.

Supreme Court of India clarifies it:

The Honorable Supreme Court of India in page 90 of its its landmark Glivec judgement has clearly pronounced that all ‘incremental innovations’ may not be trivial or frivolous in nature. However, only those ‘incremental innovations’, which will satisfy the requirements of both the above Sections of the Act, wherever applicable, will be eligible for grant of patents in India. 

An opposite view:

Another paper presents a different view altogether. It states that incremental improvements on existing drugs have great relevance to overall increases in the quality of healthcare.

With the progress of the pharmaceutical industry, such drugs have helped the physicians to treat diverse group of patients. They also represent advances in safety, efficacy along with newer dosing options significantly increasing patient compliance.

The paper claims that even from an economic standpoint, expanding drug classes represent the possibility of lower drug prices as competition between manufacturers is increased’.  It states that any policy aimed at curbing incremental innovation will ultimately lead to a reduction in the overall quality of existing drug classes and may ultimately curb the creation of novel drugs.

Pricing:

Experts, on the other hand, argue, if patents are granted to such ‘incremental innovations’ at all, their prices need to be determined by quantifying ‘Incremental Value’ that patients will derive out of these inventions as compared to the generic versions of respective original molecules.

Use of such drugs may lead to wasteful expenditure:

A large majority of stakeholders also highlight, though many of such drugs will have cheaper or generic alternatives, physicians are persuaded by the pharma players to prescribe higher cost patented medicines with the help of expensive avoidable marketing tools, leading to wasteful expenditure for all. The issue of affordability for these drugs is also being raised, especially, in the Indian context.

  • The ‘2012 Express Scripts Canada Drug Trend Report’ unfolded that the use of higher-cost medications without offering additional patient benefits resulted in waste of $3.9 billion annually in Canada.
  • Another recent Geneva-based study concluded as follows:

Evergreening strategies for follow-on drugs contribute to overall healthcare costs. It also implies that policies that encourage prescription of generic drugs could induce saving on healthcare expenditure. Healthcare providers and policymakers should be aware of the impact of evergreening strategies on overall healthcare costs.”

  • Some other studies reportedly revealed, “Medicines sold in France are 30 times more expensive than what it costs pharmaceutical companies pay to manufacture them.” Industry observers opine, if that is happening in France what about India? Quoting experts the same report comments, “If pharmaceutical companies are forced to follow moral and human values, it could save the tax payer at least 10 billion euros, an amount which could fill up the deficit of the national health care system.
  • Yet another article questioned, “What if a physician is paid speaking or consulting fees by a drug maker and then prescribes its medicine, even if there is no added benefit compared with cheaper alternatives?

More debate:

According to a paper titled, ‘Patented Drug Extension Strategies on Healthcare Spending: A Cost-Evaluation Analysis’ published by PLOS Medicine, European public health experts estimate that pharmaceutical companies have developed “evergreening” strategies to compete with generic medication after patent termination. These are usually slightly modified versions of the existing drugs.

Following are some brands, which were taken as examples for evergreening:

S.No.

Evergreen

Medical Condition

Original Brand

1.

Levocetirizine (Vozet) Allergies Cetirizine (Zyrtec)

2.

Escitalopram (Lexapro) Depression Citalopram (Celexa)

3.

Esomeprazole (Nexium) Acid reflux Omeprazole (Prilosec)

4.

Desloratadine (Clarinex) Allergies Loratadine (Claritan)

5.

Zolpidem Extended Release (Ambien CR) Insomnia Zolpidem (Ambien)

6.

Pregabalin (Lyrica) Seizures Gabapentin (Neurotonin)

Source: Medical Daily, June 4, 2013

In this study, the researchers calculated that evergreening – where pharmaceutical companies slightly modify a drug molecule to extend its patent, had cost an extra 30 million euros to the healthcare system in Geneva between 2000 and 2008. The authors argue that ‘evergreening’ strategies, “more euphemistically called as ‘life cycle management’ are sometimes questionable benefit to society.”

As the paper highlights, in this scenario the companies concerned rely on brand equity of the original molecule with newer and more innovative marketing campaigns to generate more prescriptions and incurring in that process expenses nearly twice as much on marketing than on research and development.

Brickbats:

In this context, recently a lawmaker rom America reportedly almost lambasted India as follows:

I’m very concerned with the deterioration in the environment for protection of US intellectual property rights and innovation in India. The government of India continues to take actions that make it very difficult for US innovative pharmaceutical companies to secure and enforce their patents in India.“ 

On this, the Indian experts comment, if the situation is so bad in India, why doesn’t  America get this dispute sorted out by lodging a formal complaint against India in the WTO, just as what India contemplated to do, when consignments of generic drugs of Indian manufacturers were confiscated at the European ports, alleging those are counterfeit medicines.

Yet another recent news item highlighted a “concerted effort, which involves letters from US corporations and business groups to the president, testimony by Obama administration officials before Congress, and lawmakers’ own critiques, came ahead of US secretary of state John Kerry’s trip to India later this month (has already taken place by now) for the annual strategic dialogue, which will precede Prime Minister Manmohan Singh’s visit to Washington DC in September.”

The report stated, the above letter complained that over the last year, “courts and policymakers in India have engaged in a persistent pattern of discrimination designed to benefit India’s business community at the expense of American jobs … Administrative and court rulings have repeatedly ignored internationally recognized rights — imposing arbitrary marketing restrictions on medical devices and denying, breaking, or revoking patents for nearly a dozen lifesaving medications.” 


At a recent Congressional hearing of the United States, a Congressman reportedly expressed his anger and called for taking actions against India by saying,

“Like all of you, my blood boils, when I hear that India is revoking and denying patents and granting compulsory licenses for cancer treatments or adopting local content requirements.”

Indian experts respond to these allegations by saying, patent disputes, patent challenges, revocation of patents, compulsory licensing etc. are all following a well-articulated judicial process of the country, where Indian government has hardly any role to play or intervene. American government and lawmakers are also expected to respect the rule of law in all such cases instead of trying to denigrate the Indian system.

The Power Play:

This short video clipping captures the Power Play in America on this matter.

The Government of India responds:

Ministry of Commerce and Industries of India reportedly countered the allegations of the United States over patents to the US Trade Representive arguing that the Indian IPR regime is fully TRIPS-compliant and Indian Patents Act “encourages genuine innovation by discouraging trivial, frivolous innovation, which leads to evergreening”.

Countries adopting the Indian model:

The above report also highlighted as follows:

  • Argentina has issued guidelines to reject ‘frivolous’ patents.
  • Peru, Columbia, other South American countries have placed curbs.
  • Philippines has similar provisions.
  • Australia is contemplating making the law tougher.

Revised report of Dr. R. A. Mashelkar Committee:

Even the revised (March 2009) ‘Report of the Technical Expert Group (TEG) on Patent Law Issues’, the TEG, chaired by the well-known scientist Dr. R.A. Mashelkar, in point number 5.30 of their report recommended as follows:

“Every effort must be made to prevent the practice of ‘evergreening’ often used by some of the pharma companies to unreasonably extend the life of the patent by making claims based sometimes on ‘trivial’ changes to the original patented product.  The Indian patent office has the full authority under law and practice to determine what is patentable and what would constitute only a trivial change with no significant additional improvements or inventive steps involving benefits.  Such authority should be used to prevent ‘evergreening’, rather than to introduce an arguable concept of ‘statutory exclusion’ of incremental innovations from the scope of patentability.”

Bouquets:

As stated above, many experts across the world believe, the criticism that Section 3 (d) is not TRIPS Agreement compliant is unfounded, as no such complaint has been lodged with the World Trade Organization (WTO) in this matter, thus far. The safeguards provided in the patent law of India will help the country to avoid similar issues now being faced by many countries. Importantly, neither does the section 3(d) stop all ‘incremental innovations’ in India.

Quoting a special adviser for health and development at South Centre, a think tank based in Geneva, Switzerland, a recent report indicated, “Many developing countries will follow India’s example to protect the rights of their populations to have access to essential medicines”.

Yet another report quoting an expert articulates, “India’s top court’s decision affirms India’s position and policy on defining how it defines inventions from a patenting point of view for its development needs. It challenges the patenting standards and practices of the developed countries which are the ones really in much need of reform.

The Honorable Supreme Court in its Glivec judgment has also confirmed that such safeguard provisions in the statute are expected to withstand the test of time to protect public health interest in India and do not introduce any form of unreasonable restrictions on patentability of drug inventions.

Conclusion:

Not withstanding the report of the US-India Business Council (USIBC) titled ‘The Value of Incremental Innovation: Benefits for Indian Patients and Indian Business’, arguing for abolition of section 3(d) of the Indian Patents Act to pave the way for patentability for all types of incremental innovations in pharmaceuticals, realistically it appears extremely challenging.

As the paper quoted first in this article suggests, denial of patents for inventions of dubious value extending effective patent period through additional patents, is a significant safeguard to protect public health interest. This statutory provision will also pave the way for quick introduction of generics on expiry of the original patent.

Taking all these developments into active consideration, keen industry watchers do believe, for every effort towards balancing IPR with Public Health Interest, both brickbats and bouquets will continue to be showered in varying proportion together with the mounting pressure of power play, especially from the developed world and still for some more time.

However, in India this critical balancing factor seems to have taken its root not just deep and strong, but in all probabilities - both politically and realistically, the law is now virtually irreversible, come what may.

A Force Multiplier: An “Armageddon”: A Contender for Supremacy in the Generic Pharma World

It is very important for any country to ensure access to most appropriate medicines for the patients as and when they require. In many disease areas such access can be remarkably improved through affordable generic drugs, which offer significant savings in cost for absence of monopolistic situation and intense competitive pressures.

In many countries like, India and China to further augment this process, the Government price control on essential medicines is already in force.

A paper titled, “Generic Medicines: Essential contributors to the long-term health of society” highlights the following facts on such drugs:

• Provide an affordable, gold standard medication for many major illnesses

• Allow access to medicines for a greater proportion of the population

• Stimulate healthy competition with the branded sector

• Deliver savings to national health bills

• Are high quality products

Generic companies also innovate:

The same paper also highlights, though innovation has been traditionally perceived as the domain of the research-based originator companies, generic medicine companies often spend significant sums on innovating and improving formulations, enhancing delivery systems and finding solutions to patient compliance issues.

It also says, the generics medicine industry spent 7 percent of revenues on R&D alone, in 2007 and created 150, 000 jobs only in the EU.

Continuous growth of generic drug industry is critical:

Taking all these factors into consideration, continuous growth of the generic drug industry is critical in ensuring broad access to medicines to the population of any country at an affordable price. Nothing else can achieve this objective.

In the developed countries like, Canada, Denmark, Germany, Netherlands, UK and even USA, large volume of generic medicines are prescribed. Most of these countries have put in place appropriate regulations that facilitate market entry of generic drugs soon after patent expiry. All of them, by and large, encourage even more prescriptions of generic medicines.

Of course, there are many instances of deliberate attempts to slow down generic entry, which I shall deal with separately at some other time.

Quality perception for generic drugs:

In many countries the general perception of efficacy and safety standards of generic drugs is still not satisfactory. In many occasions, these are reportedly prompted by well orchestrated campaigns by interested private stakeholders in this area.

However, in markets, like the EU, Canada and the USA Governments do take public awareness measures to dispel such doubt. Unfortunately not enough similar initiatives have been taken in India with tangible results. The reason could probably lie in the existence of a powerful branded generic lobby in the country, unlike many other markets of the world.

The market:

A report of Frost & Sullivan titled, “Generic Pharmaceuticals Market – A Global Analysis” stated, the global generic pharmaceuticals market registered a revenue of US$ 135.85 billion in 2010 with a growth rate of 11 percent. The top eight global markets, namely the United States, Germany, France, the United Kingdom, Canada, Italy, Spain and Japan account for 80 percent of the total generics market. The United States will continue to remain the largest market in the world for generic pharmaceuticals in value terms.

It is estimated, the global generic drug market will grow to US$ 231.02 billion by 2017 with a CAGR 9.3 percent from 2010. The key growth drivers being:

  • Patent expiration of some blockbuster drugs
  • Entry of more biosimilars
  • High growth of emerging markets
  • Cost containment measures of governments and healthcare service providers in various countries

BRIC Countries strongly defend generic drugs:

Allegation of attacks on the generic industry by the patent holders of various drugs is also heard quite frequently.

It was reported that in a TRIPS Council meeting in mid 2012 held at the World Trade Organization (WTO), India, Brazil and China defended the right of access to cheap generic medicines by poor countries, strongly resisting attempts by the US, Japan and some other developed countries to club counterfeits or copies of patented drugs with fake or spurious ones.

They also argued that infringing intellectual property rights should not be confused with sub-standard products.

Many believe that because of the reported ‘clout of India, China and Brazil’ in the WTO, this attempt may not fructify despite such attempts.

India is surging ahead:      

It is interesting to note that out of top 10 fastest growing generic companies of the world, 4 are of Indian origin namely Glenmark, DRL, Sun Pharma and Taro (owned by Sun Pharma) and 3 definitely are home grown Indian companies, as follows:        

Top 10 Fastest Growing Generic Companies of the World:

No. Company Country Sales US$ Million Growth 2011 (%) Growth 2010 (%)
1. Sagent Pharmaceuticals USA 152 106 153
2. Perrigo USA 620 80 45
3. Nichi-Iko Pharmaceutical Japan 1300 79 25
4. Watson Pharmaceuticals USA 3320 46 38
5. Glenmark India 778 37 17
6. Dr. Reddy’s Laboratories (DRL) India 1480 34 15
7. Taro Pharmaceutical Israel 436 33 11
8. Sun Pharmaceuticals India 1650 29 52
9. Veropharm Russia 156 24 28
10. Polpharma Poland 580 22 20

India the pharmacy of the developing world:

According to a recent report India is now emerging as the ‘Pharmacy of the Developing World’, as it produces a large volume of high-quality, affordable generic medicines.

The study also highlights, “as a result of tough competition from the generic players of India, the price of first-line ARVs dropped from more than US$ 10,000 per person per year in 2000 to around $150 per person per year today. This significant price decrease has helped to facilitate the massive expansion of HIV treatment worldwide: more than 80 percent of the HIV medicines used to treat 6.6 million people in developing countries come from Indian producers, and 90 percent of pediatric HIV medicines are Indian-produced.

Another study indicates, as a result of phenomenal success of the homegrown pharmaceutical companies:

  • 67 percent of medicines exports from India go to developing countries.
  • Main procurement agencies for developing countries’ health programs purchase their 
medicines in India, where there are quality products at low prices.
  • Approx. 50 percent of the essential medicines that UNICEF distributes in developing countries 
come from India.
  • 75-80 percent of all medicines distributed by the International Dispensary Association (IDA) to 
developing countries are manufactured in India. (IDA is a medical supplier operating on a 
not-for-profit basis for distribution of essential medicines to developing countries.)
  • In Zimbabwe, 75 percent of tenders for medicines for all public sector health facilities come from 
Indian manufacturers,
  • The state procurement agency in Lesotho, NDSO, states it buys nearly 95 percent of all ARVs 
from India.

This situation is going to further improve at a galloping pace in the years ahead with proper encouragement from the Government of India.

India tops the chart for ANDAs:

India, with its rapidly growing homegrown generic players, continues to top the Chart for Abbreviated New Drugs Applications (ANDAs) with USFDA by increasing its share year after year, as follows:

Moreover, domestic pharmaceutical companies have now between themselves, around 175 USFDA and approximately 90 UK-MHRA approved manufacturing units, to cater to the needs of high quality and affordable pharma products across the world. 

India not loosing its R&D Focus:

Discovery of new drugs being the bedrock for the pharmaceutical industry, domestic Indian companies are also not loosing focus on R&D activities. The New Chemical Entity (NCE) pipeline of the homegrown companies as on 2012 is as follows:

Piramal Healthcare 23
Suven Life Sciences 14
Zydus Cadila 11
Glenmark 8
Biocon 7
Torrent Pharma 6
Sun Pharma 5

Is the “west pressurizing India to change tack?”

In an interesting article published in ‘The Guardian’, the author observed that the western Pharmaceutical companies are putting health of world’s poor at risk. It commented that India makes cheap medicines for poor people around the world, but the EU, pharmaceutical firms and now the US are pressuring the ‘pharmacy of the developing world’ to change track. The same sentiment was echoed in another article published in Pharma Times.

However, the experts do feel that the Government of India, mostly due to intense public pressure, is well prepared to address any such situation, come what may. Thus, despite any retarding forces coming into play, the incessant march of the home grown pharmaceutical companies in search of excellence, especially in this space, is expected to continue even at a brisker pace.

The triggering factor:

Experts opine that the reason for excellence of the domestic Indian pharmaceutical industry, especially in the generic pharma landscape, is due to the amendment of the Indian Patents Act in 1970 allowing only process patents for drugs and pharmaceuticals.

The Government of India reportedly had taken such a path-breaking decision in the 70’s to lay the foundation of a vibrant domestic pharmaceutical industry capable of manufacturing low cost and high quality modern medicines for the health security of the country leveraging latest technology, including IT.

This decision was also directed towards creation of ‘drug security’ for the country as in the 70’s India was very heavily dependent on drug imports and the domestic pharmaceutical industry was virtually non-existent. 

Conclusion:

Paying kudos to the pharmaceutical ‘Crown Jewels’ of India, many industry watchers feel that the global pharma players are now keener than ever before to work with the domestic pharma industry, in various areas of business. This augurs well for all, as it will help creating a win-win situation to add further momentum to the growth of the pharmaceutical industry of India.

Be that as it may, taken in entirety and strengthened by its well-balanced patent laws, India  will continue to have a significant force multiplier effect to emerge as a global force to reckon with, particularly in this important space.

In tandem, with other significant cutting edges, as mentioned above, India is now well poised to be an “armageddon” – a contender of supremacy as a “pharmacy of the developing economies” despite selective allegations and  detrimental efforts by some vested interests.
