Form 10-K for the fiscal year ended December 31, 2004

Management`s Discussion and Analysis of Financial Condition and
Results of Operations

Results of Operations

Years Ended December 31, 2004, 2003 and 2002

Research and Development Expenses, page 19

1. Please expand your disclosure by referring to the Division of
Corporation Finance "Current Issues and Rulemaking Projects
Quarterly
Update" under section VIII - Industry Specific Issues - Accounting
and Disclosure by Companies Engaged in Research and Development
Activities.  You can find it at the following website address:
http://www.sec.gov/divisions/corpfin/cfcrq032001.htm#secviii.

Please disclose the following information for each of your major
research and development projects:

a. The current status of the project;
b. The costs incurred during each period presented and to date on
the
project;
c. The nature, timing and estimated costs of the efforts necessary
to
complete the project;
d. The anticipated completion dates;
e. The risks and uncertainties associated with completing
development
on schedule, and the consequences to operations, financial
position
and liquidity if the project is not completed timely; and finally
f. The period in which material net cash inflows from significant
projects are expected to commence.

Regarding b., if you do not maintain any research and development
costs by project, disclose that fact and explain why management
does
not maintain and evaluate research and development costs by
project.
Provide other quantitative or qualitative disclosure that
indicates
the amount of the company`s resources being used on the project.

Regarding c. and d., disclose the amount or range of estimated
costs
and timing to complete the phase in process and each future phase.
To
the extent that information is not estimable, disclose those facts
and circumstances indicating the uncertainties that preclude you
from
making a reasonable estimate.



Summary of Critical Accounting Policies, pages 20-22

2. It appears your critical accounting estimates are a reiteration
of
your significant accounting policies disclosed in your Notes to
Consolidated Financial Statements. We believe your disclosure in
Management`s Discussion and Analysis regarding your critical
accounting estimates should avoid this duplication and could be
improved to better explain the judgments and uncertainties
surrounding these estimates and the potential impact on your
financial statements.  Please refer to Section V of SEC Release
No.
FR-72. We believe that disclosures explaining the likelihood that
materially different amounts would be reported under different
conditions or using different assumptions is consistent with the
objective of Management`s Discussion and Analysis.

Liquidity and Capital Resources, pages 24-25

3. We believe your discussion of material changes in the
components
of cash flows could be improved. Consistent with Section IV of SEC
Release No. FR-72, your discussion should focus on the primary
drivers of and other material factors necessary to an
understanding
of the company`s cash flows and the indicative value of historical
cash flows.  Where there has been material variability in
historical
cash flows, focus on the underlying reasons for the changes, as
well
as on the reasonably likely impact on future cash flows and cash
management decisions.  Include a discussion and analysis of known
trends and uncertainties.

Financial Statements and Supplementary Data

Notes to Financial Statements

3. Summary of Significant Accounting Policies & Practices

Revenue Recognition, page 37

4. Please expand your disclosures, and explain to us, the method
used
to recognize deferred license fees and milestone over the expected
performance period.  For milestone payments for which the
completion
of the earning process is not yet complete, please revise your
disclosures to clarify why the payment is recognized over the
performance period of the milestone payment.  Please explain to us
why no revenue is recognized for the proportion of the efforts
completed to date upon achieving the milestone.

Inventory, page 38

5. We note your policy of generally fully reserving finished goods
inventory except for amounts deemed saleable by management based
upon
current or anticipated orders.  Further, we note that you fully
reserved the finished goods inventory balance at December 31, 2004
and had a finished inventory balance of $82,399, net of a reserve
of
$1.6 million at December 31, 2003.  Yet, you had product sales of
$3.3 million in 2004.  Please disclose, and explain to us, how
management estimates the reserves based on current or anticipated
orders to state the inventory at lower of cost or market.  Tell
why
your finished goods inventory had a market value of zero at
December
31, 2004.

Patents and Other Intangibles, page 38

6. We note your policy to defer patent and trademark costs until
successful outcome of relevant applications.  Please explain to us
your basis under GAAP for deferring these patent and trademark
costs
and why recognizing these costs as an expense prior to the
successful
outcome of the application is not appropriate.
