Ways in which Plant-Derived
Drugs are Developed
(1) Random Screening
(2) Investigations by ethnobotanists, followed
by purification and testing

Disagreement concerning the relative efficacy
of these two approaches
--ICBG-Peru Project estimates (2) is 4 times
more efficient

Rosy Periwinkle
 Species probably originates in the West
Indies, spreads to many tropical countries,
including Madagascar
 Traditional Uses:


treatment of diabetes (reported in Jamaica and
Philippines)
treatment of sore throat, pleurisy, dysentery
Rosy Periwinkle
 Eli Lilly tests samples from Madagascar


ineffective for diabetes
effective for childhood leukemia
 Eli Lilly secures patents on two derivatives
-- vincristine and vinblastine


increase remission rate from 20% to 80%
annual revenue exceeds $200,000,000
Pueraria
Pueraria
 Located in Thailand
 Traditional Thai use:


estrogen booster

 Two Japanese pharmaceutical companies
seeking patents on purified forms of its
active ingredient

President Mwinyi:
“Most of us in developing countries find
it difficult to accept the notion that
biodiversity should [flow freely to
industrial countries] while the flow of
biological products from the industrial
countries is patented, expensive and
considered the private property of the
firms that produce them. This asymmetry
reflects the inequality of opportunity
and is unjust.”

What do the providers of
Knowledge/Genetic Material Want?
 Credit


Co-inventor status
Other forms of acknowledgment
 Payment



Up-front fees for access
Payments in stages as drugs are developed
Share of profits if drug is successful
 Indemnification for the costs of preserving biodiversity
 Participation

Training of local scientists in ICBG projects
Possible Reforms
1)
LDCs deny patent protection to drugs and plants developed from
local materials (novelty; naturally occurring substance)
2) LDCs recognize prior user rights
3) LDCs amend patent law to make plants or traditionally medicinal
uses thereof patentable locally
4) DCs constrict rights associated with drug patents
5) DCs treat holders of biocultural knowledge as coinventors
6) Physical Exclusion of Bioprospectors
7) National Natural Resources Laws
8) Deals between individual countries and pharmaceutical firms
(e.g., Costa Rica; ICBG Projects)
9) Cartel of Tropical Gene-Rich Countries
10) TRIPS reform: violation of natural-resources laws = affirmative
defense (cf. inequitable conduct; patent misuse) or basis of a
compulsory license
Possible constrictions of the rights
associated with drug patents
 Expanded definitions of prior art (e.g.,
elimination of publication requirement for
inventions in use in other countries)
 Narrowing of the “purified substance”
doctrine
 Elimination of extended term (HatchWaxman)
