Patent Linkage: an important step yet to be taken by the Government of India for proper enforcement of product patents granted in the country

The process of Patent Linkage establishes a desirable communication process between the Health Ministry and the Patent Offices to prevent marketing approval of generic drugs before expiration of patents granted in India. It also ensures that one Government Department / Ministry does not impair the efforts of another Government Department / Ministry to provide effective intellectual property protection as required by Article 28 of the WTO TRIPS Agreement.
The system of Patent Linkage exists around the world:Following are some examples:

Australia – Health Authorities do not provide marketing approval for a generic copy which would infringe an existing patent.

Brazil – As of 2006, no copies of products still under patent have been launched in the market place. However, the Brazilian Health Agency (ANVISA), grants registration to copy products, based only on the merits of the case from the regulatory point of view, whether or not a patent has been granted for the same.

Canada – Health Regulatory Authorities do not provide marketing approval for pharmaceutical products protected by patents listed in the equivalent of the US FDA Orange Book.

China – The State Food & Drugs Administration (SFDA) must be satisfied that no patent is being infringed before it will issue marketing approval. If there has been litigation over a patent, SFDA will wait until the appeals process has been exhausted before acting.

Jordan – Marketing approval for a pharmaceutical product is not permitted during the period of patent protection.

Mexico – Applicants seeking marketing approval for generic pharmaceutical products in Mexico must certify that their patent rights are not infringed. The Health Regulatory Authorities then check with the Patent Office, which must respond within ten days to confirm whether a patent is involved. While Health Authorities will accept an application of marketing approval during the patent period, grant of marketing approval will be delayed until the patent expires.

Singapore – Applicants seeking marketing approval for generic pharmaceutical products in Singapore must declare that the application does not infringe any patent.

U.A.E – The Health Regulatory Authorities do not provide marketing approval for pharmaceutical products that remain under patent protection in the country.

U.S.A – U.S. FDA maintains a listing of pharmaceutical products known as the Orange Book. The Electronic Orange Book is also available via the internet at: http://ww.fda.gov/cder/ob The U.S. FDA does not authorize the marketing approval for a generic copy of a pharmaceutical product protected by a patent listed in the Orange Book.

Europe – Instead of Patent Linkage, the period of data exclusivity is for 10/11 years.

The Patent Linkage System is in progress in countries like Bahrain, Chile, Dominican Republic – Central America FTA (DR-CAFTA), Morocco and Oman.

Some people question why should India follow Patent Linkage system in the regulatory approval process?

In India ground realities in the patent enforcement process are quite unique. Thus there is an urgent need for having a Patent Linkage system in place for the following reasons:

1. The Government is granting product patent to encourage, protect and reward innovation in India, it will not be in the best interest of the innovators if the same Government grants marketing approval for a generic equivalent of the patented molecule during the patent life of the product.

2. Unlike many other countries, the Indian Patent Law has provision for both pre-grant and post-grant oppositions. Therefore, if anyone wants to challenge the patent, enough time will be available for the same.

3. After patent is granted for a product in India, if marketing approval is given to a generic equivalent of the same molecule, a dispute or patent infringement may arise. As per the Patents Act 2005, such disputes regarding patent infringement have to be challenged in a High Court. The judicial process is a long drawn one and it is quite possible that the patent life of the concerned molecule would expire during the dispute settlement period, which in turn, would raise doubts about the sanctity of granting a product patent to an innovator in our country.

Conclusions:

I therefore submit the following recommendations to ensure proper enforcement of products patent in India:

 The status of the grant of patent should be reviewed, through appropriate drug regulatory mechanism, before granting marketing permission to generic formulations and if the concerned innovative product is already patented in India, marketing permission for the generic formulation should be withheld.

 Appropriate mechanism/system should soon be worked out in co-ordination with other Ministries to avoid cases of infringement of product patents in India.

 The procedure (Patent Linkage) of checking the patent status of a product before granting marketing approval already exists in the Form 44. This procedure needs to be implemented.

India has instances where marketing permission has been granted by the DCGI for a generic product even when a product patent already exists for the same molecule in India. Such instances put the patent holder in a hardship and avoidable litigation involving huge resources both in terms of time and money. Situation like this can be effectively avoided by ascertaining the patent status before granting marketing permission to a generic manufacturer through an appropriate drug regulatory system, as indicated above.

R&D and Protection of IPR related to Pharma sector, are now the responsibilities of the Department of Pharmaceuticals (DoP) – a quick look at the initiatives taken by the department.

On July 2, 2008, the Cabinet Secretariat of the Government of India notified creation of a new department to be known as the Department of Pharmaceuticals (DoP) under the Ministry of Chemicals and Fertilisers with an objective to have a sharper focus on the Pharmaceuticals Industry of India. In that notification besides other important areas, Research and Development (R&D) and protection of Intellectual Property Rights (IPR) related to the Pharmaceutical sector, were brought under the newly created department.In this discussion let us try to have a look at the progress in both the R&D and IPRareas, separately.After creation of the new department, the Minister of Chemicals and Fertilisers Shri Ram Vilas Paswan, announced a proposed allocation of Rs. 10,000 crores (around US$ 2 billion), together with necessary regulatory reforms, towards annual Pharmaceutical R&D funding by the DoP.

The Government expects that such initiatives will help bringing in transformation of the Indian Pharmaceutical Industry from brilliant and highly successful ‘imitators’ to world class ‘innovators’ of path breaking medicines. Discovery of such medicines in India is also expected to help the Government significantly, to improve access to affordable innovative modern medicines to the common man of the country. All these are no doubt, very laudable initiatives by the DoP, with a very capable, effective and a ‘can do’ leader at its helm.

The DoP plans to bring in significant changes in the clinical trial facilities available within the country. Currently even very basic clinical trials on ‘dogs’ cannot be undertaken because of protests from the activists related to ‘prevention of cruelty on animals’. Such reform measures, I am sure, will be sincerely welcomed by many.

It is interesting to note that the DoP is also planning to extend Regulatory Data Protection (RDP) to innovators. It has been reported that the invaluable data generated by the innovators towards development of the New Molecular Entity (NME) will, in near future, be protected from ‘piracy’ during 20 year patent life of the product. However, the DoP cautions that attempt to ‘evergreen patent’ through data protection, beyond the patent life of a product will not be permitted.

The argument of the innovators on this issue is that Product Patent and Clinical Data are two different types of intellectual properties and should not be considered as one and the same. While patent protection is extended for discovery of the molecule, data protection is for the immense and expensive clinical data that the innovators share with the Government for regulatory approval of the patented molecule, within the country. The argument that such valuable data generated by the innovators is an intellectual property (IP), lies in the premise that if the innovator would not have been required to part with the data with the regulatory authorities, such data would have been regarded as a ‘trade secret’, which is an IP. Therefore, the innovators argue that for sharing this IP with the Government, specific period of data protection to be extended to them, which should be unrelated to the life of the patent.

Thus far, we see that DoP has taken some very important and admirable initiatives to encourage R&D within the country. However, while looking at another important area of its responsibility i.e. protection of IPR within the Pharmaceutical sector, nothing has been announced by the department, as yet.

Encouraging R&D without effective protection of IPR, points towards an incomplete agenda to effectively address pharmaceutical product innovation related issues by the department. I sincerely hope that the DoP will soon announce its policy initiatives towards IPR protection to further encourage the innovators, both within and outside the country.

The DoP has taken some significant steps to address various important issues of the pharmaceutical industry under its terms of reference, within a very short period. I look forward to knowing from the DoP the detail initiatives in each of its nine functions and responsibilities, as announced in the notification of the cabinet secretariat on July 2, 2008.
