Today’s Program
• Patent Basics (national and
international law)
• Access to Inputs
• Access to Outputs
Patent Basics
20 year right to exclude others
From making, using, selling, importing the invention
Must first show that the invention is
• novel
• non-obvious (inventive step)
• useful (capable of industrial application)
What can’t be patented?
(in the US)
35 U.S.C. 101: “Whoever invents or discovers any
new and useful process, machine, manufacture, or
composition of matter, or any new and useful
improvement thereof, may obtain a patent therefor”
can’t patent abstract ideas, formulas,
“phenomena of nature”
what if a scientist discovers that an elevated level of a
protein corresponds to a vitamin deficiency? (Metabolite)
or a surgeon comes up with a new surgery?
What can be patented (relevant
to medical research?)
• new compounds (“AZT”)
• a new use of a known compound (“AZT against HIV”)
• a salt of a known compound (“the besylate salt of
known compound X”)
• an ester, isomer, enantiomer, prodrug of known
compound
• a combination of known compounds (“AZT + 3TC”)
• a process for making a drug (esp. imp. in biotech)
• genetically engineered organisms (“OncoMouse™”)
• “isolated” nucleic acid sequences  (BRCA1)

TRIPS Agreement
• 153 members of WTO
• Must provide patents “without discrimination as to the
place of invention, the field of technology, and whether
products are imported or locally produced” (Art. 27.1)
• May exclude “diagnostic, therapeutic, and surgical
methods” as well as “plants and animals other than
microorganisms” (Art. 27.3)
• Patents must last at least 20 years
• Limited exceptions:
– Article 30 (“Bolar” exception, research exception?)
– Article 31 (government use and compulsory licensing)

Other solutions for “access in”
• Move research to jurisdiction w/ FTO
• Open source (with funders prompting?)
• “Patent Pools”
“Access Out”
• Open access
• At cost pricing
The Effects of Generic Competition
From Médecins Sans Frontières, Untangling the Web of ARV Price
Reductions (July 2008).
Pros of open access
• harnesses power of competitive dynamics
• less oversight / don’t need to define “at cost”
• innovation benefits?
Pros of at cost pricing
• may be more acceptable to licensee
• in some areas competition (generics)
may be less likely
Issues for “Access Out” Licenses / Agreements
• territories (LMI? HDI? Burden of disease? Sectors?)
• fields of use
• definitions
• of end product and IP for OA (background tech?)
• of “at cost” for ACP (and audits?)
• drug registration and adequate supply (for ACP)
• in-licensed technologies…
•Technical assistance, regulatory data
