Re: Patent Document
Dear Xx. Xxxxxx:
Texas Tech University understands the need for extension of the legal
protection for its patented HemoTech(TM) blood substitute product, which was
licensed to HemoBioTech, Inc., for commercial development [U.S. Patent No.
5,439,882, issued August 8, 1995]. Therefore, Texas Tech made a decision to
initiate this process even with limited financial resources, and looks forward
to working with HemoBioTech in filing a new patent application for HemoTech(TM).
Knowing that the new patent must be compatible with an earlier
established commercial development strategy, Xx. Xxxxxx, a co-inventor of
HemoTech(TM), has worked on new claims related to "a method of treatment." Since
the most important therapeutic action of HemoTech(TM) in the treatment of acute
blood loss is based on the replacement of a patient's own red blood cells, the
present invention relates to a method of stimulating erythropoiesis (production
of red blood cells in the body) by this blood substitute. If approved, such a
medical claim will protect the patented composition and preclude others from
using this invention for commercial purpose such as use as a blood substitute.
At this moment any changes to the * of HemoTech(TM) could * the
possibility of using the * and * * at FDA in the HemoTech(TM) U.S. IND process.
Moreover, the * * of HemoTech(TM) can * the * * data on a product. Therefore,
the only method of protecting

HemoTech(TM) while preserving the existing *, research and clinical data is in
HemoTech's medical application.
While the commercial development of HemoTech(TM) blood substitute will
remain the main objective of HemoBioTech's activity, in the future changes in
the chemical composition of HemoTech(TM) may occur in order to create new
products which can be optimized for different clinical uses.
In a recent study conducted by Xx. Xxxxxx, HemoTech(TM) was found to *. *
are critical molecular steps necessary for the stimulation of erythropoesis.
Previous clinical research showed that HemoTech(TM) stimulates the
erythropoietic response in patients with sickle cell anemia. These scientific
observations are the main driving force in the proposed patent application.
It is the intention to submit to the U.S. Patent and Trademark Office a
patent application as soon as possible.
SUMMARY OF PROPOSED PATENT APPLICATION:
TITLE: *
FIELD OF INVENTION: This invention relates to a method of stimulating
erythropoiesis by administration of hemoglobin-ATP-adenosine-glutathione based
blood substitute.

LICENSEE: HemoBioTech, Inc.
ABSTRACT: An improved blood substitute that comprises purified
hemoglobin, preferably bovine, cross-linked intramolecularly with o-ATP
and intermolecularly with o-adenosine and conjugated with reduced
glutathione (GSH) has erythropoietic activity, while working as a
physiological oxygen carrier. This blood substitute has prolonged
intravascular persistence, has vasodilator activity and alleviates
inflammatory reactions in sickle cell anemia patients, but also produces
effective erythropoietic response. In the recent study, this improved
blood substitute was found to

erythropoietic responses in human with acute blood loss/ or a sickle cell
anemia, which comprises intravenously administrating to the human, the
therapeutically relevant volume of this blood substitute.
