Spirit Behind Drug Patent Grant: Secondary Patents: Impact on Drug Access

For more effective treatment against existing diseases, besides combating new or a more complicated form of existing ailments with precision, drug innovation is absolutely necessary and on an ongoing basis. This makes innovative drugs so important for the population, globally.

Besides academia, the pharma industry has remained in the forefront of the search for new drugs, for so long. What makes this process so crucial is, cheaper generic drugs flow from the innovative drugs, post market exclusivity period, which together form the bedrock of the pharma industry’s business model. Consequently, a robust patent protection for the new molecular entities, not only enable the drug innovators to make a reasonably good profit, but also encourage them to keep this virtuous circle moving, faster.

Although, the drug patents are granted for 20 years, after obtaining marketing approval from the respective drug regulators, a time period - ranging between 7 and 12 years, is available to the company to realize its maximum commercial benefits. Thereafter, the patent expires, paving the way of market entry of cheaper generic equivalents to make the drug accessible to a larger population. This is the playbook, which deserves to be accepted and respected by all, both in the letter and spirit.

Currently, the narrative has started changing, apparently, repudiating the spirit behind the grant of new drug patents, especially with the entry of a number of expensive, large molecule biopharmaceutical drugs. After obtaining a fixed-term market exclusivity, more intricate legal measures are being taken to extend the fixed-term market monopoly for an unknown period, delaying market entry of cheaper biosimilar equivalents, post patent expiry, as long as possible.

In this milieu, India appears to be the only country in the world, where the country’s ‘Patents Act’ provides enough safeguard to blunt those legal tools, effectively, to protect patients’ health interest. Quite expectedly, this new narrative of the drug innovators is yielding the best return in the Eldorado of the pharma world – the Unites States. It is also no secret that US vehemently opposes several provisions of the Indian Patents Act 2005, under pressure from the most powerful pharma lobby group, as many believe.

Using the spirit behind drug patent protection as the backdrop, I shall dwell in this article, how this so precious spirit is gradually losing its basic purpose, especially for blockbuster biopharma drugs. Is the key intent behind sacrificing the spirit behind drug patent grant to keep their brands money spinners and big – even after expiry of original patent – as long as possible – at the cost of patients’ health interest?

Despite the original patent expiry, biggest biologic drugs remain big:

The fact that original patent expiries have done little to halt sales of some of the industry’s biggest products – mostly biologic drugs, was clearly elucidated in an  Evaluate Pharma article – “Biopharma’s biggest sellers – the oldies that just keep giving,” published on August 14, 2019. This gets vindicated, as we look at the ‘top ten pharma brands with biggest lifetime sales – from launch to 2018’, in the following Table I:

Product Company Launch year USD Billion
1. Lipitor Pfizer 1997 164.43
2 Humira AbbVie 2003 136.55
3. Rituxan Genentech/Biogen 1997 111.50
4. Enbrel Amgen 1998 108.16
5. Epogen Amgen 1988 107.90
6. Advair GSK 1998 104.20
7. Remicade Janssen 1998   98.00
8. Zantac GSK 1981   97.42
9. Plavix Sanofi/BMS 1998   90.63
10. Herceptin Genentech/Roche 1998   87.97

(Adapted from Evaluate Pharma data of August 14, 2019)

The point to take note of:

The point worth noting here, with the exception of Advair, Zantac, Lipitor and Plavix, all others – among the top ten brands, are biologic drugs. Moreover, what is most striking in the Table I, despite the expiry of the original patents, a large number of biologic brands were able to expand their sales, pretty impressively, for well over two decades. As we shall see later, this situation is expected to continue, at least, till 2024.  As the Evaluate Pharma article states, for various reasons, these multibillion dollar brands have been able to avoid the expected post patent expiry ‘onslaught from biosimilars in the key US market’, which is incidentally the most valuable pharma market in the world.

One of the key reasons that helps delaying cheaper biosimilar drug entry expanding patient access, is a crafty strategic measure adopted by these companies through the creation of a Patent Thicket with secondary patents. As I discussed in this Blog on April 22, 2019, this is a crafty way of ‘evergreening’ patent term beyond 20 years, legally. Whether such measures conform to the spirit of granting 20 years product patent, becomes a moral question, or an issue of probity for the concerned companies, at the most. Be that as it may, a concern over this situation has been raised in many countries, including the United States.

Barrier of secondary patents: 

Biosimilar drug developers continue facing multiple non-financial challenges, such as, scientific, regulatory, pricing. I have already discussed some of these barriers in this blog on July 31, 2017. Instead, I shall focus in this article, with greater detail, on the intricate and a well-woven net of secondary patents. However,before delving into this area, it will be worthwhile to have a quick recap on the basic differences between original patents and secondary patents.

According to WIPO, “Patents on active ingredients are referred to as primary patents. In later phases of the drug development, patents are filed on other aspects of active ingredients such as different dosage forms, formulations, production methods etc. These types of patents are referred to as secondary patents.”

Another excellent paper, authored by two distinguished researchers from Columbia University and LSE, makes some important points on this subject. It says, secondary patents have become increasingly important to the pharma industry, especially in the U.S. and Europe over the past three decades. The basic purpose of ‘taking out multiple patents on different aspects of a drug in order to cordon off competitors is now standard practice in the pharmaceutical industry.’ As the authors further said, this is primarily because: ‘Secondary patents can protect market shares by extending periods of exclusivity beyond the dates in which patent protection would otherwise lapse.’

Interestingly. devising patent strategies to extend periods of market exclusivity is generally considered in the industry, as a key component of ‘product life cycle management,’ – not by the marketing whiz kids, but by astute patent attorneys. Nevertheless, as the paper articulates, critics of this practice often use the more pejorative – evergreening, to describe it.

Examples of impact of secondary patents:

Many research papers suggest, besides scientific complexity in biosimilar drug development being a key reason for their delayed market entry, secondary patents are even tougher barriers for the same. This was brought to light a few years ago in a ‘Review Article’ – ‘The Economics of Biosimilars’, published in the September/October 2013 issue of American Health & Drug Benefits.

Some of the key points made on this issue include,AbbVie plan to defend Humira (adalimumab) with more than 200 secondary patents, Merck’s giving up its biosimilar project on Enbrel when Amgen got its expanded patent life. There are many other such instances.

Its effect would last longer: 

Experts believe, the effect of creating a strong secondary patent shield around blockbuster biologic would last much longer. As the above Evaluate Pharma article underscores: ‘This ability to fend off biosimilar competition is one of the reasons Humira is set to snatch Lipitor’s crown next year as the industry’s most successful drug.’

The Table II below that lists ‘top 10 pharma brands from their respective launch date, including estimated forecast till 2024’, vindicates its long-lasting impact:

Product Company Launch year USD Billion
1. Humira AbbVie 2003 240.05
2 Lipitor Pfizer 1997 180.19
3. Enbrel Amgen 1998 139.83
4. Rituxan Genentech/Biogen 1997 136.07
5. Revlimid Celgene 2008 123.64
6. Remicade Janssen 1998 117.20
7. Epogen Amgen 1988 115.87
8. Herceptin Genentech/Roche 1998 114.89
9. Avastin Genentech/Roche 2004 114.27
10. Advair GSK 1998 113.61

(Adapted from Evaluate Pharma data of August 14, 2019)

Although, Zantac and Plavix no longer feature in this table, one drug that leapfrogged much of the competition to become one of the industry’s biggest future bestsellers is Revlimid. The projected sales of the drug over the next six years will actually outstrip its sales to date. However, much of this is dependent on whether generic competition will arrive ahead of Revlimid’s 2022 patent expiry, the paper indicated.

Concern expressed even in the US for the delay in biosimilar market entry:

Many big spending countries on health care, such as the United States expected that timely biosimilar drug entry will help contain health expenditure significantly. However, the article published in the Fierce Pharma on August 29, 2019, raises an alarm, but with a hope for the future. It says: “It’s no secret biosimilars haven’t made a big dent in U.S. drug spending. Some experts have even said it’s time to give up on copycat biologic.”

This hope gets resonated with what, ‘the former US-FDA commissioner Scott Gottlieb argues’. He feels, ‘It’s too soon for that’, while ‘calling on Congress to bolster the budding market.’ However, in my personal view, this will remain a difficult proposition to implement, as biologic drug players will continue using their relatively new, but powerful weapon of filing a number of complex ‘secondary patents.’ These will help extend the market exclusivity period of their respective brands, much beyond the original patent grant period, unless a counter legal measures are taken by the lawmakers of various countries, including the United States. But, India is an exception in this regard.

Indian patent law doesn’t encourage ‘secondary patents’:

The good news is, Indian Patent Act 2005, doesn’t encourage ‘secondary patent.’ This is because, section 3 (d) of the Indian Patent Act 2005 limits grant of ‘secondary pharmaceutical patents.’ An interesting study reported on February 08, 2018, discussed about 1,700 rejections for pharma patents at the IPO spanning over the last decade. But, there is a huge scope for improvement in this area.

Which is why, the not so good news is under-utilization of the same section 3.d by the Indian Patent Office (IPO), as are being voiced in many reports. One such paper of April 25, 2018 highlighted,72 per cent of pharma patent grants are secondary patents. These were granted for marginal improvements over previously known drugs for which primary patents exist. That said, despite such reported lapses, blocking of some crucial secondary patent grant has benefited a large number of patient population of India.

Blocking secondary patent grant has helped India immensely:

While US recognizes secondary patents, blocking secondary patent grant, especially for biologic drugs has helped Indian patients immensely, with expanded access to those medicines. This was also captured in the above study. Besides the classic case of Novartis losing its secondary patent challenge for Glivec in the Supreme Court of India in 2013, several other examples of secondary patent rejection are also available. This includes, among others, Glivec of Novartis and the world’s top selling drug for several years – Humira of AbbVie.Against a month’s therapy cost of ₹1,6o, ooo for Glivec in the US, its Indian biosimilar version costs for the same period ₹11,100. Similarly, while the treatment cost with Humira in the US is ₹85,000, the same with its biosimilar version in India is ₹ 13,500, as the above study finds.

Conclusion:

The core purpose of drug innovation, as widely touted by the R&D-based drug companies, is meeting the unmet needs of patients in the battles against diseases. Thus, drug innovation of this genre must not just be encouraged, but also be adequately protected and rewarded by granting product monopoly for a 20-year period from the date of the original patent grant. Curiously, piggybacking on this basic spirit behind the drug patent grant, pharma lobby groups are now vocal on their demand for giving similar treatment to secondary patents on various molecules. The tone of demand gets shriller when it comes to section 3. d of the Indian Patents Act, which doesn’t allow such ‘evergreening’ through secondary patents.

Thus, the key question that surfaces, while the original patent grant for innovative drugs help meeting unmet needs of some patients, whose unmet needs would a secondary patent grant meet, except making the concerned company richer? Further, for highly expensive biologic drugs, delayed market entry of cheaper biosimilars in that process, would deny their expanded access – failing to meet the unmet needs of scores of others.

Hopefully, India won’t give in to pressure of multinational pharma lobby groups, channeled through various powerful overseas government entities. At the same time, I hope, the government in power at the Eldorado of the pharma industry, will consider giving a fair chance of market entry to cheaper biosimilars, including those from India, to also grow their business globally, but in a win-win way.

The key objective of all stakeholders involved in this process, should be to uphold the basic spirit behind drug patent grant. It may even call for challenging the core intent behind secondary patent applications, the world over, that deny quicker market entry for cheaper biosimilars, sans heavy litigation expenses. This will help expand access to cheaper biologic medicines to all those who can’t afford those, otherwise.

Patent Conundrum: Ignoring India Will Just Not be Foolhardy, Not An Option Either

The recent verdict of the Supreme Court against Novartis, upholding the decision of the Indian Patent Office (IPO) against grant of patent to their cancer drug Glivec, based on Section 3(d) of the Indian Patents Act, has caused a flutter and utter discontentment within the global pharmaceutical industry across the world.

However, on this verdict, the Director General of the World Trade Organization (WTO), Pascal Lamy has reportedly opined, “Recent decisions by the courts in India have led to a lot of protest by pharmaceutical companies. But decisions made by an independent judiciary have to be respected as such.”

The above decision on Glivec came close on the heels of IPO’s decision to grant its first ever Compulsory License (CL) to the Indian drug manufacturer Natco, last year, for the kidney cancer drug Nexavar of Bayer.

Interestingly, no member of the World Trade Organization has raised any concern on these issues, as the Head of WTO, Lamy recently confirmed, No country has objected to India issuing compulsory license or refusing patent for drugs.” He further added, TRIPS provides flexibilities that allow countries to issue compulsory licenses for patented medicines to address health urgencies.”

That said, simmering unhappiness within innovator companies on various areas of Indian patent laws is indeed quite palpable. Such discontent being expressed by many interested powerful voices is now reverberating in the corridors of power both in India and overseas.

Point and Counterpoint:

Although experts do opine that patent laws of India are well balanced, takes care of public health interest, encourage innovation and discourage evergreening, many global innovator companies think just the opposite. They feel, an appropriate ecosystem to foster innovation does not exist in India and their IP, by and large, is not safe in the country. The moot question is, therefore, ‘Could immediate fallout of this negative perception prompt them to ignore India or even play at a low key in this market?’

Looking at the issue from Indian perspective:

If we take this issue from the product patent perspective, India could probably be impacted in the following two ways:

  1. New innovative products may not be introduced in India
  2. The inflow of Foreign Direct Investments (FDI) in the pharma sector may get seriously restricted.

Let us now examine the possible outcome of each of these steps one at a time.

Will India be deprived of newer innovative drugs?

If the innovator companies decide to ignore India by not launching such products in the country, they may take either of the following two steps:

  1. Avoid filing a patent in India
  2. File a patent but do not launch the product

Keeping the emerging scenario in perspective, it will be extremely challenging for the global players to avoid the current patent regime in India, even if they do not like it. This is mainly because of the following reasons:

1. If an innovator company decides not to file a product patent in India, it will pave the way for Indian companies to introduce copy-cat versions of the same in no time, as it were, at a fractional price in the Indian market.

2. Further, there would also be a possibility of getting these copycat versions exported to the unregulated markets of the world from India at a very low price, causing potential business loss to the innovator companies.

3. If any innovator company files a product patent in India, but does not work the patent within the stipulated period of three years, as provided in the patent law of the country, in that case any Indian company can apply for CL for the same with a high probability of such a request being granted by the Patent Controller. 

A market too attractive to ignore:

India as a pharmaceutical market is quite challenging to ignore, despite its ‘warts and moles’ for various reasons. The story of increasing consumption of healthcare in India, including pharmaceuticals, especially when the country is expected to be one of the top 10 pharmaceutical markets in the world, is too enticing for any global player to ignore, despite unhappiness in various areas of business.

Increasing affordability of the fast growing middle-class population of the country will further drive the growth of this market, which is expected to register a value turnover of US$50 billion by 2020, as estimated by PwC.

PwC report also highlights that a growing and increasingly sophisticated pharmaceutical industry of India is gradually becoming a competitor of global pharma in some key areas, on the one hand and a potential partner in others, as is being witnessed today by many.

Despite urbanization, nearly 70 percent of the total population of India still lives in the rural villages. Untapped potential of the rural markets is expected to provide another boost to the growth momentum of the industry.

Too enticing to exit:

Other ‘Enticing Factors’ for India, in my views, may be considered as follows:

  • A country with 1.13 billion populations and a GDP of US$ 1.8 trillion in 2011 is expected to grow at an average of 8.2 percent in the next five-year period.
  • Public health expenditure to more than double from 1.1 percent of the GDP to 2.5 percent of GDP in the Twelfth Five Year Plan period (2012-17)
  • Government will commence rolling out ‘Universal Health Coverage’ initiative
  • Budget allocation of US$ 5.4 billion announced towards free distribution of essential medicines from government hospitals and health centers.
  • Greater plan outlay announced for NRHM, NUHM and RSBY projects.
  • Rapidly growing more prosperous middle class population of the country.
  • Fast growing domestic generic drug manufacturers who will have increasing penetration in both local and emerging markets.
  • Rising per capita income of the population and relative in-efficiency of the public healthcare systems will encourage private healthcare services of various types and scales to flourish.
  • Expected emergence of a robust health insurance model for all strata of society as the insurance sector is undergoing reform measures.
  • Fast growing Medical Tourism.
  • World-class local outsourcing opportunities for a combo-business model with both patented and branded generic drugs.

Core issues in patent conundrum:

I reckon, besides others, there are three core issues in the patent conundrum in India as follows, other issues can be sorted out by following:

1. Pricing’ strategy of patented products: A large population across the globe believes that high prices of patented products severely restrict their access to many and at the same time increases the cost of healthcare even for the Governments very significantly.

2. To obtain a drug patent in India, passing the test of inventive steps will not just be enough, the invention should also pass the acid test of patentability criteria, to prevent evergreening, as enshrined in the laws of the land. Many other countries are expected to follow India in this area, in course of time. For example, after Philippines and Argentina, South Africa now reportedly plans to overhaul its patent laws by “closing a loophole known as ‘ever-greening’ used by drug companies to extend patent protection and profits”. Moreover, there does not seem to be any possibility to get this law amended by the Indian Parliament now or after the next general election.

3. Probably due to some legal loopholes, already granted patents are often violated without following the prescribed processes of law in terms of pre or post – grant challenges before and after launch of such products. There is a need for the government to plug all such legal loopholes, after taking full stock of the prevailing situation in this area, without further delay.

Some Global CEOs spoke on this issue:

In this context the Global CEO of GSK commented in October 18, 2012 that while intellectual property protection is an important aspect of ensuring that innovation is rewarded, the period of exclusivity in a country should not determine the price of the product. Witty said, ‘At GSK we will continuously strive to defend intellectual property, but more importantly, defend tier pricing to make sure that we have appropriate pricing for the affordability of the country and that’s why, in my personal view, our business in India has been so successful for so long.’

Does all in the global pharma industry share this view? 

Not really. All in the global pharmaceutical industry does not necessarily seem to share the above views of Andrew Witty and believe that to meet the unmet needs of patients, the Intellectual Property Rights (IPR) of innovative products must be strongly protected by the governments of all countries putting in place a robust product patent regime and the pricing of such products should not come in the way at all.

The industry also argues that to recover high costs of R&D and manufacturing of such products together with making a modest profit, the innovator companies set a product price, which at times may be perceived as too high for the marginalized section of the society, where government intervention is required more than the innovator companies. Aggressive marketing activities, the industry considers, during the patent life of a product, are essential to gain market access for such drugs to the patients.

In support of the pharmaceutical industry the following argument was put forth in a recent article:

“The underlying goal of every single business is to make money. People single out pharmaceutical companies for making profits, but it’s important to remember that they also create products that save millions of lives.”

How much then to charge for a patented drug? 

While there is no single or only right way to arrive at the price of an IPR protected medicine, how much the pharmaceutical manufacturers will charge for such drugs still remains an important, yet complex and difficult issue to resolve, both locally and globally.

A paper titled, “Pharmaceutical Price Controls in OECD Countries”, published by the US Department of Commerce after examining the drug price regulatory systems of 11 OECD countries concluded that all of them enforce some form of price controls to limit spending on pharmaceuticals. The report also indicated that the reimbursement prices in these countries are often treated as de facto market price. Moreover, some OECD governments regularly cut prices of even those drugs, which are already in the market. 

Should India address ‘Patented Products’ Pricing’ issue with HTA model?

Though some people hate the mechanism of Health Technology Assessment (HTA) to determine price of a patented drug, I reckon, it could be a justifiable and logical answer to price related pharmaceutical patent conundrum in India.

Health Technology Assessment, as many will know, examines the medical, economic, social and ethical implications of the incremental value of a medical technology or a drug in healthcare.

HTA, in that process, will analyze the costs of inputs and the output in terms of their consequences or outcomes. With in-depth understanding of these components, the policy makers decide the value of an intervention much more precisely.

Companies like, Merck, Pfizer and GSK have reportedly imbibed this mechanism to arrive at a value of the invention. National Pharmaceutical Pricing Authorities (NPPA) may well consider this approach for a well judged, scientific and transparent pricing decision mechanism in India, especially for innovative new drugs.

Could local manufacturing be an option?

Considering relatively higher volume sales in India, to bring down the price, the global companies may consider manufacturing their patented products in India with appropriate technology transfer agreements being in place and could even make India as one of their export hubs, as a couple of their counterparts have already initiated.

Accepting the reality responsibly:

In view of the above, the global pharmaceutical players, as experts believe, should take note of the following factors. All these could help, while formulating their India-specific game plan to be successful in the country, without worrying much about invocation of Compulsory License (CL) for not meeting ‘Reasonably Affordable Price’ criterion, as provided in the Patents Act of the country:

  • While respecting IPR and following Doha declaration, the government focus on ‘reasonably affordable drug prices’ will be even sharper due to increasing pressure from the Civil Society, Indian Parliament and also from the Courts of the country triggered by ‘Public Interest Litigations (PIL)’
  • India will continue to remain within the ‘modest-margin’ range for the pharmaceutical business with marketing excellence driven volume turnover.
  • Although innovation will continue to be encouraged with IPR protection, the amended Patents Act of India is ‘Public Health Interest’ oriented, including restrictions on patentability, which, based on early signals, many other countries are expected to follow as we move on.
  • This situation though very challenging for many innovator companies, is unlikely to change in the foreseeable future, even under pressure of various “Free Trade Agreements (FTA)”.  

Sectors Attracting Highest FDI Equity inflows:

When one looks at the FDI equity inflow from April 2000 to March 2013 period as follows, it does not appear that FDI inflow in Drugs and Pharmaceuticals had any unusual impact due to ‘Patent Conundrums’ in the country at any time:

Ranks Sector

US$ Million

Conclusion:

In search of excellence in India, global pharmaceutical companies will need to find out innovative win-win strategies adapting themselves to the legal requirements for business in the country, instead of trying to get the laws changed.

India, at the same time, should expeditiously address the issue of blatant patent infringements by some Indian players exploiting the legal loopholes and set up fast track courts to resolve all IP related disputes without inordinate delay.

Responsible drug pricing, public health oriented patent regime, technology transfer/local manufacturing of patented products and stringent regulatory requirements in all pharmaceutical industry related areas taking care of patients’ interest, are expected to be the key areas to address in the business models of global pharmaceutical companies for India.

Moreover,it is worth noting that any meaningful and long term FDI in the pharmaceutical industry of India will come mostly through investments in R&D and manufacturing. Such FDI may not be forthcoming without any policy compulsions, like in China. Hence, many believe, the orchestrated bogey of FDI for the pharmaceutical industry in India, other than brownfield acquisitions in the generics space, is just like dangling a carrot, as it were, besides being blatantly illusive.

Even with all these, India will continue to remain too lucrative a pharmaceutical market to ignore by any. Thus, I reckon, despite a high decibel patent conundrum, any thought to ignore or even be indifferent to Indian pharmaceutical market by any global player could well be foolhardy.

Grant of Compulsory License for Bayer’s Nexavar in India raises more questions than answers

On March 12, 2012, the Patent Office of India, in its landmark ruling, granted its first ever Compulsory License (CL) for Bayer’s patented kidney and liver cancer drug Nexavar (Sorafenib), to the generic pharma player Natco, broadly citing the following reasons:

  • Reasonable requirements of public under Section 84 have not been satisfied.
  • The Patented Drug was not available to the public at a reasonably affordable price as per Section 84 (1) (b).
  • Patented invention is not worked in the territory of India as per Section 84 (1) (c)

The 62 page order of the Controller General of Patents, Designs and Trade Mark (CGPDTM) granted the CL to Natco for the rest of patent life of sorafenib in India at the high end of the UNDP 2001 royalty guidelines at 6 percent.

Sorafenib:

Sorafenib was co-developed and co-marketed by Bayer and Onyx Pharmaceuticals  for the treatment of advanced  renal cell and hepatocellular carcinoma. The drug got its first regulatory approval from the US FDA for advanced renal cell carcinoma in 2005.

National Institute of Health and Clinical Excellence (NICE) of UK had indicated that the drug extends life of the kidney cancer patients by three months on an average.

As stated earlier, in March 2008, Indian patent for Sorafenib was granted to Bayer by the CGPDTM. Thereafter, in December 2010 Natco had requested for a voluntary license from Bayer, which was rejected by the patentee.

It has been reported that sorafenib was registered as an ‘orphan drug’ in the US. The R&D cost of sorafenib was partly subsidized by the US Orphan Drug tax credit.

Mixed reaction:

Though the research based pharmaceutical industry across the world expressed its disappointment over the judgment, many experts and NGOs from different parts of the globe have opined that CGPDTM has set a right precedence by granting a CL for sorafenib, which will ensure, in the times to come, that patent monopolies are kept limited, especially when the patented products are not “reasonably affordable”.

Many people, therefore, envisage that the grant of the first ever CL by the Indian Patent Office could ultimately open the door for other generics players of India to apply for the same on similar grounds and mainly for ‘non-working of patents’, as many patented medicines are now imported into India by the respective global players.

Granting CL should be the last resort:

While none can deny that all citizens of India should have access to innovative and lifesaving medicines, as will be required for their medical treatment, it appears rather impractical to envisage that routine issue of CL by the Indian Patent Office will be able to resolve this critical issue on a long term basis.  Grant of CL, if any, I reckon, should be taken only after exhausting all other access improvement measures.

Working of a patent:

In this particular case, it has been decided by the CGPDTM that working of a patent will require the concerned company to manufacture the drug in India in a reasonable quantity. The argument of the CGPDTM in this respect, many experts believe, is quite a stretch of an interpretation of the statute.

This is mainly because, as one of the signatories of TRIPS, India has a national commitment for adherence to this important international agreement. It is, therefore, widely believed, if importation is not considered as working of patent, the country could expose itself to the risk of  violation of the Article 27.1 of TRIPS, both in letter and spirit.

The Article 27.1 of TRIPS:

The Article 27.1 of TRIPS on ‘local working of patents’ indicates as follows:

“1. Subject to the provisions of paragraphs 2 and 3, patents shall be available for any inventions, whether products or processes, in all fields of technology, provided that they are new, involve an inventive step and are capable of industrial application. Subject to paragraph 4 of Article 65, paragraph 8 of Article 70 and paragraph 3 of this Article, patents shall be available and patent rights enjoyable without discrimination as to the place of invention, the field of technology and whether products are imported or locally produced.”

Thus as per Article 27.1 of TRIPS, if commercialization of products patented in India, is done locally either through imports or local manufacturing, should be considered as ‘local working of patents’.

Form 27 vindicates the fact:

Form 27 of the Indian Patents Act, which is a statement regarding the working of patented inventions on commercial scale in India, in its point number 3, under ‘if worked’ states as follows:

“If worked: quantum and value (in Rupees) of the patented product:

  1. Manufactured in India
  2. Imported from other countries (give country-wise details)”

Thus, when Form 27 itself accepts importation as ‘local working of patent’, it is indeed intriguing why was the decision to the contrary taken by the CGPDTM?

Moreover, it is worth noting that the term ‘manufacture in India’ was deleted from the earlier Section 90 (a) of the Patents Act.

A statutory requirement:

CGPDTM through a circular dated December 24, 2009, directed all Patentees and Licensees to furnish information in ‘Form No.27’ on ‘Local Working of Patents’ as prescribed under Section 146 of the Patents Act.

It will be interesting to know, whether CGPDTM in response to Form 27 submissions of Bayer had informed them earlier that the Nexavar Patent has not been worked in India. If not, what is then the sanctity of Form 27 filing?

Delhi High Court Judgment:

Further, it has been well reported that in the legal case of ‘Telemecanique & Controls (I) Limited Vs. Schneider Electric Industries SA 94(2001)DLT865’ on working of patents, the Delhi High Court had concluded that importation would amount to working of Patents.

India specific pricing for innovative drugs is not uncommon:

At this stage, it is worth mentioning that India specific pricing for innovative drugs are not uncommon in the country at all. Following are some good examples:

  • GlaxoSmithKline  Pharmaceuticals has already announced its differential pricing system for India and will sell its innovative drugs at prices 25% to 40% less than what those are in the US.
  • MSD  has already introduced its India specific price for patented products. Their patented cervical cancer drug Gardasil is being sold in India at 75% -80% less than the global prices.
  • Moreover, MSD’s patented anti-diabetic drug Januvia (sitagliptin phosphate) is locally sourced and marketed at one-tenth of the global price.
  • In 2008 Novartis  reportedly tied up with the domestic pharma major USV to market its patented anti-diabetic drug Galvus (Vildagliptin) by pricing it lower than Januvia. According to reports, Novartis markets Galvus in the metros, while USV markets the same brand in tier two and three cities of India.
  • Roche  has recently collaborated with the domestic pharma player Emcure Pharmaceuticals to manufacture its two well-known biologics Herceptin and MabThera not only to cater to the domestic needs, but also for export to other developing markets.

Manufacturing of a small quantity locally – an issue:

As quoted in the order of the CGPDTM there are around 8842 eligible patients for sorafenib in India. All these patients put together will require Nexavar ranging from 27000 (Bayer’s figure) to 70000 boxes (NATCO’s figure) per year.  Thus, the moot question remains: even for such small annual requirements, should global companies set up manufacturing facilities in all the countries like, India.

Another question: if other smaller markets of the world also make local manufacturing mandatory for any pharmaceutical products that will be sold in their respective countries, will the Indian players find those markets attractive enough to expand their business? In that case who will be the net losers?… Patients?

Conclusion:

If the issue of whether importation will be considered as ‘local working of patents’ or not is not answered conclusively under higher judicial scrutiny in conformity of Article 27.1 of TRIPS and CL is granted to local manufacturers for commercial benefits under similar situation, availability of life saving innovative products in the Indian market for the patients of India could be in a real jeopardy.

The objective of improving access to innovative medicines is a very desirable one for any country like ours. However, if India routinely starts granting CL for this purpose before exhausting all other avenues to achieve this goal, it would risk sending a very wrong signal to the outside world that the country is shirking its responsibilities to create an appropriate ecosystem to foster and support pharmaceutical innovation to offer better quality of lives to the citizens of the country in particular.

In the absence of both collaboration and foreign direct investments by the global innovators in the field of pharmaceutical research and development, India may feel handicapped, especially when our neighbor China is surging ahead in this field with longer strides.

Thus, routine grant of CL, as is being envisaged by many in India, on a similar situation could, on the contrary, make the issue of access to innovative medicines by the common man even more challenging, in the longer run.

The stormy debate on wrongful grant of pharma product patents – a countdown of the news events, for a quick perspective.

To give a quick perspective to this debate, I reckon, a countdown of five reported news events on the subject will be helpful. I start from February, 2009 and gradually go one year back, to February, 2008, to capture the key elements of this stormy debate. Finally, I move to ‘ground zero’ to explore the basic remedial measures to effectively address the issue.Event 5‘The Economic times’ (ET) dated February 24, 2009 reported an interesting news item titled, “Dichotomy between patent law and practice”. The timing of this article, with its various quotes, highlighting the following points, evokes interest:

1.“Indian patent authorities are virtually not following the spirit of the Sections 3(d) and 3(e)”.

2.“A large number of patents granted in India since 2005 pertain to products first patented in 1970s, 1980s, and 1990s, most of which were launched in Indian markets long before 2005, the year of introduction of product patenting in the country”.

3.“The patent applicants are not making adequate disclosures, making it difficult for potential challengers to file post-grant objections which the law provides for. Since the International Non-proprietary Name (INN) is not of the drug is often not given along with the Title of the Patent, it is cumbersome for anyone to trace the patent to the original PCT (Patent Cooperation Treaty) application and have an idea about how new it is”.

4.“Many law firms refuse to take briefs from Indian companies, because their multinational clients do not permit them to do so! The result— post-grant objection facility is not effectively used by Indian companies.”

Why are these observations interesting?

These observations are interesting because for point number 1 to 3, as stated above, following three recourses are available to all:

1. After publication of the patent applied for, in the patent journal, one can file a pre-grant opposition.

2. Assuming that someone has missed this opportunity, the provision for filing post grant opposition will still be there.

3. Assuming that both the opportunities have been missed due to some reasons and one could not understand the details of the patent applied for, during the patent granting process, the opportunity of going to a Court of law with a request to make such patents (which have violated section 3.d) invalid, will still exist.

It is indeed very difficult to understand why such measures are not being taken by the aggrieved parties, as specified in the law.

Point number four is even more difficult to understand. When lawyers are available to the domestic companies to defend alleged patent infringement, why then lawyers will not be available to them to take such objections to a court of law?

Event 4

Mint dated October 7, 2008 in its article titled; “Cozy deals and conflicting interest mark patent granting process” reported the following:

“There are even local and multinational corporates who ‘seek’ help of examiners and controllers to get their applications drafted, thereby ensuring a grant for a price”.

Event 3

‘The Economic Times’ dated July 1, 2008 reported in its article titled, “Cipla gets patent for Nexium, Fosamax modified versions” that Mumbai Patent office granted these two patents to Cipla in April, 2008 for new forms of two well known blockbuster drugs, Esomeprazole (Nexium of Astra Zeneca) and Alendronate (Fosamax of Merck). This news came as a big surprise because Cipla is well known for its continuous accusation to innovator companies for trying to extend ‘monopoly’ period by ever-greening patent through similar means. The report, therefore, raised a very valid question, whether Cipla has ‘walked the talk’ in India? It will be interesting to know on what basis Cipla managed to overcome the ‘efficacy’ barriers under section 3(d).

On this ET report, well known IPR expert Shamnad Basheer wrote the following in his blog dated July 6, 2008:

“Reading the ET piece, Nathan Evans of Finnegan Henderson, who’s a very astute commentator on the Indian patent scene and has written a couple of articles in this regard posed this question to me:

“This makes me wonder if the patent office in India will apply the laws less strictly to Indian pharmas than MNCs (kind of like they apply the patent laws more strictly for essential medicines)”

Shamnad Basheer concluded his comment on this subject with the following observations:

“How ought section 3(d) to be interpreted when our very own generic manufacturers are applying for supposedly “incremental” inventions?”

Event 2

According to Federation of Indian Chambers of Commerce (FICCI) report dated March 7, 2008, FICCI and the Department of Industrial Policy and Promotion (DIPP), Ministry of Commerce and Industry have joined hands to set up a working group to improve Intellectual Property regime in India.
It will be interesting to know the view of this joint working group between the Government and the Industries, in this matter. I have not read anywhere any comments of this important working group on such matter, so far.

Event 1

‘Thomson and Reuters patent focus report’ dated February, 2009 observed absence of clear guidelines (Manual of Patent Practice and Procedure) about some of the complex provisions of patent law, particularly section 3(d). The report indicated that there should be clarity on what would qualify as “enhanced efficacy” under section 3(d) so that it can help the patent examiners to clearly make out which patent applications would fall under section 3(d).

Ground Zero:

Let us now try to ponder, realize and fathom the core issue of this problem, which lies at the ‘Ground Zero’. Thus far we have been reading constant allegations about the functioning of Indian Patent Offices and even on their integrity and honesty.

In absence of a well drafted, long overdue, Patent Manual, all concerned, including patent examiners will have their own ways of looking into “enhanced efficacy”. In such a situation, I shall not be surprised if the Patent Examiners suffer from the dilemma as to what exactly will constitute “enhanced efficacy”.

Protracted debate with the stakeholders on the ‘draft patent manual’ appears to be over now. The last stakeholders’ meeting on this subject was concluded in Kolkata following Delhi, Mumbai and Bangalore, several months ago. However, the final Patent Manual is still not in place, which has been kept for public inspection since 2005.

To address this stormy debate, in my view, we need to:

1. Push for expeditious release and implementation of the Patent Manual (Manual of Patent Practice
and Procedure).

2. Let FICCI – DIPP working group work more effectively and cohesively for better functioning of the
new IPR (Intellectual Property Rights) regime.

3. Let ‘capacity building’ exercise at the Indian Patent office (IPO) continue with greater speed.

Mere accusation and constant bashing of the IPOs, as we now see around, may not yield much result. After having taken the above measures, if similar dissatisfaction in any quarter still remains, let law take its own course. Despite great apprehensions by some, as quoted above under point 1, never mind, enough lawyers will be available to fight such cases.
