Madison, Wis. – In a decision that cannot be appealed, the United States Patent and Trademark Office has upheld the modified claims of the Wisconsin Alumni Research Foundation on two of the foundation’s most important human embryonic stem cell patents.
The ruling, which affects two patents for primate and human embryonic stem cells known as â??780â? and â??806,â? follows a favorable determination on patent â??913,â? which relates to the discovery and culture of human embryonic stem cells by researcher Jamie Thomson.
