Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
79 words
An oral composition comprising: (a) a safe and effective amount of a polymer selected from the group consisting of a linear polymeric carboxylate polymers or copolymers, sulfonate polymers or copolymers and sulfate polymers or copolymers; (b) a safe and effective amount of a soluble strontium ion source; (c) a safe and effective amount of a soluble fluoride ion source; and (d) an orally acceptable carrier, wherein said composition is substantially free of linear, non-crosslinked acrylic acid polymers or copolymers.
Claim 2
Dependent Claim
79 words
An oral composition comprising: (a) a safe and effective amount of a polymer selected from the group consisting of a linear polymeric carboxylate polymers or copolymers, sulfonate polymers or copolymers and sulfate polymers or copolymers; (b) a safe and effective amount of a soluble strontium ion source; (c) a safe and effective amount of a soluble fluoride ion source; and (d) an orally acceptable carrier, wherein said composition is substantially free of linear, non-crosslinked acrylic acid polymers or copolymers.
Claim 3
Dependent Claim
39 words
An oral composition according to Claim 1 wherein the polymer utilizes a material selected from the group consisting of crotonic, sorbic, alpha-chlorsorbic, cinnamic, muconic, itaconic, citraconic, mesaconic, glutaconic, aconitic, angelic, umbellic, fumaric, maleic acids and anhydrides and sulfonic acid.
