Consumer Advocates Support Patent Office on Stem Cell Patent Rejection

Date:11/5/2007

SANTA MONICA, Calif., Nov. 5 /PRNewswire-USNewswire/ -- Amended stem cell patent claims submitted by the Wisconsin Alumni Research Foundation don't overcome the U.S. Patent Office Examiner's rejections and the claims remain unpatentable, two consumer groups said today.

In formal comments filed Friday the Foundation for Taxpayer and Consumer Rights (FTCR) and the Public Patent Foundation (PUBPAT) asked that the rejections first issued on March 30 by the U.S. PTO be made final.

"Stem cell science would be best served if WARF simply withdrew their overreaching claims," said John M. Simpson, FTCR's stem cell project director.

In July 2006 the FTCR and PUBPAT challenged three patents held by WARF because they are hindering stem cell research. Stem Cell Scientist Dr. Jeanne Loring supported the challenge, which led to the rejection of all claims of all three patents in March.

In June WARF offered counter arguments and then in October filed what it described as "technical amendments" to the patent claims.

"Upon review, however, none of those amendments are sufficient to overcome the Examiner's rejections," wrote Daniel B. Ravicher, PUBPAT's executive director. "As such, the claims remain unpatentable."

Four internationally known stem cell scientists, Loring of the Burnham Institute for Medical Research, soon to join the Scripps Research Institute; Dr. Douglas Melton of Harvard University; Dr. Alan Trounson of Monash University in Australia, soon to take over as president of the California Institute for Regenerative Medicine; and Dr. Chad Cowan of Harvard University filed declarations supporting the consumer groups and the PTO's earlier finding that the work done by Dr. James Thomson does not deserve a patent.
