The Role of Patents in the

Pharmaceutical Industry

Regional Seminar on multilateral legal framework and practice of patent protection in the pharmaceutical field

Peter R. Thomsen, IP Policy and Litigation

Issyk Kul, May 27&28, 2014

The healthcare environment is undergoing unprecedented change

Aging population

The world’s population is aging. More healthcare treatments are needed, which is prompting payors to aggressively manage costs

Unhealthy lifestyles

Poor nutritional habits and sedentary lifestyles are increasing the prevalence of chronic diseases

Emerging markets

Economic growth in emerging countries is expanding access to healthcare

Advances in science and technology

New technological discoveries and trends are enabling the development of innovative medicines but also increasing the cost of innovation

3 | Practice of Patent Protection in Pharma | P.R. Thomsen | May 27, 2014 | Role of Patents for pharmaceuticals

Originator Business

Innovative drugs with substance patent protection

• Small chemical entities

• Biologics, e.g. antibodies

Requiring a prescription

Products available in pharmacies and hospitals

All kinds of mostly potentially severe medical conditions

• Oncology

• Cardiovascular

• Antibiotics and antivirals

4 | Practice of Patent Protection in Pharma | P.R. Thomsen | May 27, 2014 | Role of Patents for pharmaceuticals

Generic Business

Drugs which have lost (compound) patent protection

Generic product also needs marketing approval from

Health Authorities and needs to show to be safe and equally effective compared to originator reference product

Drugs requiring a prescription

• since around 10 years including follow-on biologics or biosimilars

Products available in pharmacies and hospitals in the same way originator products are available

5 | Practice of Patent Protection in Pharma | P.R. Thomsen | May 27, 2014 | Role of Patents for pharmaceuticals

OTC

(over - the - counter)

Drugs typically without patent protection or with patent protection only for certain aspects of the formulation

Drugs requiring no or no longer a prescription

Usually for less severe medical conditions

• pain killer

• cough and cold

• allergy

Products available in drugstores and pharmacies

6 | Practice of Patent Protection in Pharma | P.R. Thomsen | May 27, 2014 | Role of Patents for pharmaceuticals

Vaccines

Products are antigens to stimulate the patient’s immune response

Antigen itself often not patent protected

But formulation, adjuvants, production processes, technology and combinations are patent protected

Prevention against severe infectious conditions, e.g.

• Influenza, including pandemic

• Against «children diseases»

• New generation of vaccines against e.g. cervical cancer

No significant generic activity (so far)

Products available in pharmacies and hospitals

Case Example: Cyclosporin microemulsion

• Cyclosporin used in drug for immune suppression after transplantation

• Compound/indication patent for Cyclosporin expired 1995

• 1988 improved formulation invented with micro-emulsion

• Formulation patents filed and granted

Claims of Micro-emulsion patent:

“1. A pharmaceutical composition comprising a cyclosporin as active ingredient,

1) a hydrophilic phase,

2) a lipophilic phase, and

3) a surfactant, which composition is an oil-in-water microemulsion pre-concentrate."

16 | Practice of Patent Protection in Pharma | P.R. Thomsen | May 27, 2014 | Role of Patents for pharmaceuticals

Case Example: Cyclosporin microemulsion (ctd)

• Patentee claimed patent infringement by a generic product in development by IVAX called «Equoral(R)»

Composition of Equoral(R) i) Cyclosporin (9%); ii) Polyglycerol (3) oleate (30%); iii) Polyglycerol (10) oleate (30%); iv) Macrogolglycerate hydroxystearate (27%);

Lipophilic phase ?

Surfactant v) Ethanol (15%);

Hydrophilic phase vi) Fatty acids (~1%); vii) [capsules only] D,L-( tocopherol (vitamin E, an antioxidant)(<1%).

• GB High Court found no separate lipophilic phase component and only 14% of Cyclosporin in micelles similar to a microemulsion

• Overall no oil-in water microemulsion and patent therefore not infringed!

• Confirmed in Court of Appeal (Novartis v Ivax [2007] EWCA Civ 971)

Two Objectives of IP-Functions

Protecting own R&D investments by obtaining and enforcing IP-rights

Ensuring Freedom-To-Operate against IP-rights of others

18 | Practice of Patent Protection in Pharma | P.R. Thomsen | May 27, 2014 | Role of Patents for pharmaceuticals

IPR Enforcement and Freedom-to-Operate

Enforcement of Patents in Court litigation very common

• To ensure a certain period of exclusivity

• To recuperate high R&D costs

• To push third parties to take licenses (rare for pharmaceuticals, more common for e.g. diagnostics)

Freedom-to-Operate

• To make sure patents of others are not infringed

• By legally designing-around the patents

• By invalidate potentially relevant third party patents

 If Development / TechOps would select “direct” approach

(red): probably being held infringing 3 patents

Patent Function:

• Identifying a way through and around protection of third party patents!

• Cannot design around compound patent (covers every form, use, production of compound)

22 | Practice of Patent Protection in Pharma | P.R. Thomsen | May 27, 2014 | Role of Patents for pharmaceuticals

Successful Designing Around Third Party Patents

Process and intermediate patents: find an alternative manufacturing process that is not likely to be held infringing

Indication patents: consider carving-out of labeling and marketing authorization

Formulation patents: find an alternative formulation that meets regulatory requirements (Bioequivalency) but is not likely to be held infringing

23 | Practice of Patent Protection in Pharma | P.R. Thomsen | May 27, 2014 | Role of Patents for pharmaceuticals

Example for successful Designing Around :

Cefuroxime Axetil

GSK held patent on special formulation of cefuroxime axetil having a film-coating:

Gx developed a Cefuroxime Axetil tablet being bioequivalent but having a non-film coating

Gx product was launched well before expiry of film-tablet

GSK patent and

24 | Practice of Patent Protection in Pharma | P.R. Thomsen | May 27, 2014 | Role of Patents for pharmaceuticals

Example for successful Designing Around

GSK sued and asked for a preliminary injunction (PI)

Court refused PI and Gx could stay on the market

GSK withdrew claim on patent infringement of film-coating tablet

Successful design-around!

Main tools for dissolving patent conflicts

Patent infringement litigation started by patentee in view of actual or imminent launch of an allegedly infringing product

Request for Declaratory Judgement of Noninfringement started by alleged infringer

Revocation action started by potentially alleged infringer

• Administrative route, e.g. opposition

• Court route

Formal linkage between patent status and ability of

Health Authorities to issue generic marketing authorization («patent linkage»)

28 | Practice of Patent Protection in Pharma | P.R. Thomsen | May 27, 2014 | Role of Patents for pharmaceuticals

Key elements of strong IP-regime

• Complying with standards set by international agreements

- TRIPS, PLT and PCT, Paris Convention, Madrid Agreement/Protocol

• Limited Exclusions from Patentability, e.g. for biotechnological inventions

• Efficient procedures to examine and grant patents and trademarks

• Strong Court system allowing effective enforcement of IP-rights

- availability of timely preliminary measures

- Enforceability of court decisions

- Ideally specialized IP-Courts

- Possibility to have patent validity re-examined

• Availability of Trademark protection

29 | Practice of Patent Protection in Pharma | P.R. Thomsen | May 27, 2014 | Role of Patents for pharmaceuticals

Key elements of strong national IP-regime (contd)

• Willingness of local authorities to combat against counterfeiting

- Customs

• Regulatory Data Exclusivity

- Sufficiently long period

- to protect regulatory data from being disclosed and being referred to by unauthorized third parties

• Possibility to obtain patent term extensions to compensate for regulatory delays

- E.g. for up to 5 years

30 | Practice of Patent Protection in Pharma | P.R. Thomsen | May 27, 2014 | Role of Patents for pharmaceuticals

Conclusions

Different drug businesses use patents in different ways

Establishing and maintaining strong national IPR-regimes is essential to ensure that companies can continue to undertake the costly and risky R&D process to develop next generations of innovative medicines and vaccines

Intellectual property rights can also stimulate technology transfer and building of technical skills within developing countries and fuel economic growth

Robust national procedures to obtain and enforce IP-rights such as patents, trademarks and regulatory data exclusivity

Also for generic sector efficient mechanisms to decide on patent disputes are important , e.g. on non-infringement or validity of granted patents in the interest of legal and business certainty

Many barriers exist that prevent access to healthcare and medicines, including lack of sustainable financing and inadequate infrastructure and supply systems.

It is critical to address the entire health system in order to improve health outcomes
