LIDAK Pharmaceuticals Receives New Patent Allowance On Human
Immune System in Non-Human Animal

LA JOLLA, Calif., July 17 /PRNewswire/ -- LIDAK Pharmaceuticals (Nasdaq:NNM - news) announced today that it had
received notification of allowance from the U.S. Patent and Trademark Office for patent application #08/543,449 for Human
Immune System in Non-Human Animal. This new patent is a continuation to patent #5,476,996 which issued in 1995 and is
assigned to LIDAK. The original patent covered a strain of mouse known as C.B-17 scid/scid into which human peripheral
blood leukocytes had been engrafted, thereby creating a model of the human immune system. The term scid is an acronym for
severe combined immune deficient. The new patent will extend coverage to other strains of scid/scid mice and production of
human antibodies in these mice, including monoclonal antibodies, and provide protection from individuals using these
experimental models without license.

Mouse models covered by the LIDAK patents are useful in conducting immunological research and are particularly useful
compared to primates for testing drugs against HIV (Human Immunodeficiency Virus). Mice prepared using the method in the
patents can be readily infected with the human virus yet are more flexible and far less expensive than primate models. These
mouse models are also useful for producing human antibodies. LIDAK makes non-exclusive licenses to the model available to
interested parties. Southern Research Institute in Birmingham, Alabama conducts commercial testing for clients using the
LIDAK model under license.

Commenting on the announcement, David H. Katz, M.D., LIDAK's president and chief executive officer, stated, ``This patent
reflects many years of groundbreaking research in the development of novel animal models that can more accurately and
inexpensively mimic the human immune system. The hu-PBL- SCID model continues to support scientific advancements in the
treatment of human immune system diseases, particularly HIV and AIDS.''

The comercialized mouse models will fetch a handsome profit for LIDAK
this is greatttttt... I will place my order before the Christmas rush.. to be sure and have some for the holidays...

I wonder if Bud can tell us how much these mice sell for??? anybody??
and I can imagine there is good margin in them and experiments should require lots o'mice..for sake of statistical significance.. Although experiments sometimes have surprisingly low numbers of mice..
I wonder if its lack of statistical foundation on the part of the scientists, lazy science or the mice are too costly or the medicine they test is limited in production quantity ...all of the above I suppose.

LIDAK may be able to sue one or two disreputable outfits pirating their immune system mice models... from reading between the lines... I think its another wonderful surprise for us..investors.. and another product for them.
