1. Introductory concepts
Doctrine of exhaustion
Typical types of exhaustion
Factors to balance
Singapore’s balance of access and protection for
patented pharmaceutical products
Lam Pak Nian, 2013/2014
2. What is exhaustion?
• An intellectual property right is the negative
right to exclude
– A patent, inter alia, allows the owner to exclude
others from making or selling an invention
• Right to exclude is limited by ‘exhaustion’
– IPR owner’s control over the physical product
ends once the product is first sold
– Purchaser is free to use or resell that product
without further restraint from patent law
Lam Pak Nian, 2013/2014
3. Parallel imports
• Exhaustion of rights provides the legal basis
for parallel imports
– Parallel imports are goods produced and sold
legally but subsequently exported into another
jurisdiction
• Take advantage of pricing differences, etc
• Parallel imports take advantage of the
purchaser’s right to resell
– Genuine goods, unauthorised resale

IPRs in good exhausted once it is sold in any country
Exhausted when sold in
any country
Position in country:
International exhaustion

6. Regional exhaustion
Pill image: D Dinneen
IPRs in good exhausted only when it is sold within the region
Position in country/region:
Regional exhaustion
Exhausted when
sold in region
Not exhausted
when sold
outside region

7. National exhaustion

Exhausted when
sold in country
Not exhausted when
sold anywhere
outside country

9. Balance?
More access
(allow parallel imports)
More protection
(block parallel imports)
Consumers and
governments want to be
able to get pharmaceutical
products
Pharmaceutical companies
want to be able to
segregate the world and
price discriminate
Public health
considerations
Incentive and reward
Features of chosen exhaustion regime have an important
impact on the parallel trade of pharmaceuticals
