Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
84 words
A topical preparation for the treatment of skin fungus infections and psoriasis, comprising: (a) undecylenic acid; (b) a phosphorous-containing acid which forms orthophosphoric acid in the presence of water or air; and (c) a solvent for said (a) and (b); said (b) comprising between about 5% and about 85% by weight of the total weight of said (a) and (b), and said (a) and (b) comprising between about 25% and about 75% by weight of the total weight of said (a), (b) and (c).
Claim 2
Dependent Claim
84 words
A topical preparation for the treatment of skin fungus infections and psoriasis, comprising: (a) undecylenic acid; (b) a phosphorous-containing acid which forms orthophosphoric acid in the presence of water or air; and (c) a solvent for said (a) and (b); said (b) comprising between about 5% and about 85% by weight of the total weight of said (a) and (b), and said (a) and (b) comprising between about 25% and about 75% by weight of the total weight of said (a), (b) and (c).
Claim 3
Dependent Claim
24 words
The preparation of claim 1 wherein said solvent is a lower molecular weight alcohol selected from the group consisting of ethanol and isopropyl alcohol.
Claim 4
Dependent Claim
30 words
The preparation of claim 2 wherein said solvent includes water in a minor amount with respect to said alcohol such that said undecylenic and phosphorous-containing acids are maintained in solution.
Claim 5
Dependent Claim
81 words
An intermediate preparation for combination with a solvent for said intermediate preparation to provide a topical preparation comprising about 25% to about 75% by weight of said intermediate preparation for the treatment of skin fungus infections and psoriasis, said intermediate preparation comprising (a) undecylenic acid and (b) a phosphorous-containing acid which forms orthophosphoric acid in the presence of water or air, said (b) comprising between about 5% and about 85% by weight of the total weight of said (a) and (b).
Claim 6
Dependent Claim
81 words
An intermediate preparation for combination with a solvent for said intermediate preparation to provide a topical preparation comprising about 25% to about 75% by weight of said intermediate preparation for the treatment of skin fungus infections and psoriasis, said intermediate preparation comprising (a) undecylenic acid and (b) a phosphorous-containing acid which forms orthophosphoric acid in the presence of water or air, said (b) comprising between about 5% and about 85% by weight of the total weight of said (a) and (b).
Claim 7
Dependent Claim
32 words
The intermediate preparation of claim 4 wherein said phosphorous-containing acid is a material selected from the group consisting of: ortho- and metaphosphoric acid; pyrophosphoric acid; hypophosphoric acid; hypophosphorous acid; and phosphorous acid.
Claim 8
Dependent Claim
121 words
A topical preparation for the treatment of skin fungus infections and psoriasis, comprising: (a) undecylenic acid; (b) a phosphorous-containing acid member which is a material selected from the group consisting of ortho- and metaphosphoric acid, pyrophosphoric acid, hypophosphoric acid, hypophosphorous acid and phosphorous acid, said acid member comprising about 5% to about 85% by weight of the total weight of said (a) and (b); and (c) a solvent for said (a) and (b) consisting of a major portion of an organic solvent selected from the group consisting of ethanol and isopropyl alcohol and a minor portion of water, said (a) and (b) comprising between about 25% and about 75% by weight of the total weight of said (a), (b) and (c).
