The battle over whether excessive protection of stem
cell IP stifles research that can lead to cures was engaged once more today
with a broadside against the powerful Wisconsin Alumni Research Foundation(WARF).
The attack came from California’s Consumer Watchdog
organization and New York’s Public Patent Foundation which have been tussling
with WARF for seven years. The dispute over
intellectual property (IP) centers on a patent on human embryonic stem cells
held by WARF and which the other organizations are challenging in a federal
appellate court in Washington, D.C.
More specifically, the patent involves research by
Jamie Thomson of the University of Wisconsin, and now also of UC Santa Barbara,
in which he isolated human embryonic stem cells.
Consumer Watchdog of Santa Monica, Ca., this morning
issued a news release concerning the organizations’ appellate brief that was filed last
week. It cited the U.S. Supreme Court ruling earlier this year that said genes
cannot be patented because they exist in nature. The lead attorney in that successful case, Dan
Ravicher of the Public Patent Foundation, is also handling the challenge to WARF.
The news release said that Thomson deserved credit
for being first to isolate and maintain human embryonic stem cells, but “his achievement was not the result of
his having created a patentable invention.” The brief said that the work involved
was “obvious.” One of the main reasons for Thomson’s achievement, the news
release said, was that “he had
access to human embryos and financial support that other researchers did not
have.”
The brief said,
“The claims at issue here cover human embryonic stem (hES) cells that are not markedly different from those in our bodies. Thus, the claims are invalid under 35 U.S.C. § 101 for covering ineligible subject matter, an issue the Court may and, as a matter of judicial economy and public policy, should address.”
The challenge to the WARF
patent has drawn impressive support in the scientific community, including Jeanne Loring, now director of the Center for
Regenerative Medicine at The Scripps Research Institute, who was involved from
the start. In 2007, Loring wrote in Nature that she became involved in the case
because “scientists have an obligation not only to perform research but to make
sure that our research can benefit the society that supports it.”
The news release said,
“Later in the case Dr. Alan Trounson, then of Australia’s Monash University and now president of the California Institute for Regenerative Medicine, Dr. Douglas Melton of Harvard and Dr. Chad Cowan of Harvard filed affidavits supporting the challenge.”
