In re Application of: Maes, et al. 

Serial No.: 09/773,351 Group Art Unit 1619 

Filed; January 3 1 , 2001 Examiner: Willis, M. 

For: Cholesterol Sulfate and Amino Sugar Compositions for Enhancement of Stratum Comeum Function 


The Assistant Commissioner of Patents and Trademarks 
Washington, D.C. 2023 1 
Dear Sir: 

In response to the Final Action of December 12, 2001, and the Advisory Action dated March 26, 
2002, please consider the following remarks regarding the rejections which were maintained therein. The 
Examiner maintained the rejection of claim 19 under section 112, first paragraph for failing to describe 
subject matter such that one of ordinary skill in the art would be enabled to make and/or use the present 
invention. Specifically, the Examiner asserts that the specification lacks enablement for "preventing" 
damage to the skin. The Examiner's position is based on the reasoning that damage to the skin cannot be 
adequately predicted such that it is not possible to determine if damage has been prevented. In addition, in 
response to the submission of other patents using the term "preventing", the Examiner points out that each 
application is examined on its own merits. 

Knowledge of certain factors, such as f for example, chronological aging or overexposure to UV 
radiation based on studies of the changes in the skin subjected to a specific factor makes it possible to 
predict damage to the skin. Thus, while damage to the skin cannot be predicted in its entirety, there are 
specific types of damage that the skin may experience and that are indeed predictable. As an illustration, 
predictability of the damage to the skin is demonstrated in U.S. Patent No. Re. 36,068. In this document, at 
columns 3 to 4, the predictable characteristics of sundamaged and aging skin are described. Similar to Re. 
36,068, Claim 19 does not broadly describe damage to the skin; but rather, addresses a specific type of 
damage. In Claim 19 the damage is that which is associated with a reduction or loss of skin barrier function, 
and the characteristics of this damage are described in the present specification. Specifically, at page \, line 
26 to page 2, line, examples of a compromised skin barrier are provided as being UV-damage, degradation 
of collagen and elastin, and wrinkling and skin atrophy. Therefore, there is an ability based on knowledge in 
the art regarding aging and sundamaged skin to permit with great accuracy the prediction of damage

associated with a reduction or loss of skin barrier function. It is important to note that the damage referred 
to in Claim 19 is not open-ended damage to the skin but instead is limited to damage to the skin's protective 
barrier function. 

The Examiner also reasons that "prevention" of a symptom is not the same as a reduction of a 

definition of the word "prevent" as it is defined in the Webster's Encyclopedic Unabridged Dictionary of the 
English Language ("the Dictionary") at page 1 141 means "to keep from occurring/' lliere is no mention of 
a correlation with reducing the thing that is kept from occurring, presumably because they are two different 
words. However, if a condition already exists the fact that it is possible to reduce that condition inherently 
means that it is not occurring any further. One of ordinary skill in the art understands the scope and 
meaning of the word "prevent" as it used in the present invention. Therefore, Applicants request that the 
Examiner's rejections based on lack of enablement under 35 U.S.C. § 1 12, first paragraph be withdrawn. 

The Examiner also maintains in the advisory action that Ribier et aL (U.S. Patent No. 5,650,166; 
"the '166 reference") in view of Subbiah (U.S. Patent No. 6,150,381; u the '381 reference") renders claims 1 
to 20 of the present invention obvious under 35 U.S.C. § 103(a) because a mixture includes random solutions 
and vesicles. In response to Applicants' previous arguments regarding the teachings of the '166 reference, 
the Examiner points out that the '166 reference teaches the formation of vesicles by mixing. However, the 
second category of vesicles which is taught as being capable of formation by simple stirring does not teach 
or suggest a simple mixture of an exfoliant and cholesterol sulfate which are the actives of the present 
invention. The present invention relates to a mixture of cholesterol sulfate and an exfoliant which can be N- 
acetylglucosamine. Specifically, the 1 166 reference teaches N-acetyl-glucosamine as being an active agent 
with deep down action at column 5, line 67 (i.e., encapsulated in the first category vesicle B) 1 Production of 
vesicles of first category (diffusing deep down)), it is not taught as a second category active for diffusing at 
the surface. Therefore, the teaching of second category vesicles containing surface diffusing actives by 
simple stirring with a lipid system in Table I fails to teach or suggest the present invention because N-acetyl 
glucosamine is not taught in the * 166 as being a surface diffusing active. 

As the Examiner points out, at column 8, line 23, of the '166 reference, the production of vesicles of 
the second category (diffusing at the surface) are taught, however, the simple stirring is of the second 
category active into a particular type of lipid system disclosed in Table 1 which will act as the membrane for 
the lipid. Thus, while it appears that the vesicle can be formed by simple stirring according to the '166 
reference in one of the lipid systems of Table 1 7 the vesicle is then added to the cosmetic composition which 

symptom. However, Applicants submit herewith a dictionary definition of the word "prevent." The 


flPR-12-2002 17:52 EL COMPANIES 516 531 1340 P. 08 

* also contains first category vesicles. This is evidenced by the section heading B) Production of the cosmetic 
composition. Therefore, there is no teaching of a simple mixture of cholesterol sulfate with N- 
acetylglucosamine in a composition, and thus, no teaching or suggestion of the present invention by the ' 166 

Further, the ' 166 reference teaches away from the present invention because the teaching of N- 
acetyl glucosamine in the '166 reference is as a deep down active which is encapsulated according to the 
elaborate process in B) Production of vesicles of first category (diffusing deep down). As previously 
mentioned in the Applicants' Reponse of March 12, 2002, the process of making lipid vesicles taught or 
suggested by the 1 166 reference would not provide motivation to one of ordinary skill in the art to make the 
simple mixture of the present or to achieve the surprising results of the present invention. The '166 
reference demonstrates the exact opposite of the present invention. With respect to N-acetyl glucosamine as 
a deep diffusing active, the '166 reference teaches that co-fusion processing steps are required to make the 
first category vesicle which is distinguishable over a simple mixture. Further, even if a vesicle can be made 
as described in the section for second category vesicles by simple stirring, the second category vesicles are 
still composed of a surface diffusing active encapsulated by a lipid system which is added to a cosmetic. 
The exfoliant, namely N-acetyl glucosamine, of the present invention is not taught in a simple mixture with 
cholesterol sulfate, therefore, the 466 reference, alone or in combination with the '381 reference, fails to 
teach or suggest the present invention. Because neither of the cited references alone nor in combination 
would lead one of ordinary skill in the art to the compositions and methods of the present invention, a prima 
facie case of obviousness has not been established. Applicants request therefore, that the Examiner's 
rejection under §103 be withdrawn. 


In view of the arguments presented above in the present submission, the claims are believed to be in 
condition for allowance, and issuance of a Notice of Allowance is respectfully solicited.

Various effects of photo aging or sundatnage of skip includ- 
ing impairment of differentiation of epidermal epithelial 
cells and loss of collagen hbers, abnormal changes in clastic 
fibers and deterioration of small blood vessels in the dermis 
of the sldn are retarded by applying topically to the epider- 
mis in a maintenance therapy program effective amounts of 
retinoids including retinoid derivatives and stereoisomers 
thereof such that epithelial growths are substantially reduced 
and prevented and the skin substantially regains and main- 
tains its firmness, turgor and elasticity. Moreover with 
persistent treatment dermal blood cells and vessels increase 
and the epidermis and dermis thicken, resulting in improved 
ability of the skin to sense, resist and recover from irritation 
or injury. Further, hyperpigmcntation, lines and wrinkles due 
to aging are reduced and prevented. The treatment is par- 
ticularly useful for human facial skin and preferably applied 
in amounts insufficient to cause excessive irritation.
