Stem cell patent

The Washington Post reports that the USPTO has revoked three patents granted to Wisconsin Alumni Research Foundation for inventions involving human embryonic stem cells. The Foundation has said that it will appeal, and the governor of Wisconsin has said that it will back the Foundation.

The IPKat notes that a patent involving stem cells filed by the same organisation is currently before the EPO Enlarged Board of Appeal.

  1. The USPTO has not revoked the patents. The patents are undergoing re-examination. The USPTO has issued Actions rejecting all claims of the 3 patents. WARF has yet to respond. The outcome has not been decided yet. My understanding is that if the patents are revoked, WARF will appeal

  2. WARF gave us Warfarin. Originally it killed rodents but since they have become resistant it is widely dispensed to humans.


All comments must be moderated by a member of the IPKat team before they appear on the blog. Comments will not be allowed if the contravene the IPKat policy that readers' comments should not be obscene or defamatory; they should not consist of ad hominem attacks on members of the blog team or other comment-posters and they should make a constructive contribution to the discussion of the post on which they purport to comment.

It is also the IPKat policy that comments should not be made completely anonymously, and users should use a consistent name or pseudonym (which should not itself be defamatory or obscene, or that of another real person), either in the "identity" field, or at the beginning of the comment. Current practice is to, however, allow a limited number of comments that contravene this policy, provided that the comment has a high degree of relevance and the comment chain does not become too difficult to follow.
