Evolving Patent Law in the New Age of Biomedical Science

BIOMEDICAL SCIENCE
ROBERT BLACKBURN'
The United States Constitution gives us a clear purpose for
the patent system: to promote the progress of science. We live
in an unprecedented age of medical science, which is extremely
fortunate. With the discovery of new pathogenic viruses, such as
HIV and the Hepatitis-C virus, and the emerging threat of
prions, the cause of mad cow disease, it is clear that we are in a
biological war. It is possible to lose this war. Regardless of the
constitutional purpose behind the patent system, never before
have we had a greater need to encourage the progress of
medical science.
While the patent system2 has undoubtedly promoted the
progress of the traditional pharmaceutical industry, does that
system promote the vital progress we need in today's cutting-
edge biomedical technologies? You might guess that I would not
raise the question if I thought the answer was an unqualified
yes. To examine the patent system's shortcomings we must
look at the intersection of law, policy, and some sophisticated
science.
There is a significant difference between biotechnology and
traditional  pharmaceutical     chemistry.   An    oversimplified
distinction  between    the   two   is  as  follows. Traditional
pharmaceutical chemistry, if you went back twenty-five years or
so, focused on the basic structures of small chemical compounds
that had pharmaceutical activity. The chemist would start with
what is called a lead compound that had a desirable activity.
