Summary for Patent: 8,460,641
Title:Microemulsion process and composition
Abstract: An oil-in-water microemulsion or sub-micron emulsion composition for dermal delivery of at least one pharmaceutically active ingredient, comprising: a first part including at least one occlusive agent and one or more lipophilic surfactants dispersed throughout a second part including water and at least one hydrophilic surfactant, and a non-surfactant amphiphilic type compound, pharmaceutically active ingredient, and water. It has been found that if a non-surfactant amphiphilic type compound is added together with the second part as would conventionally be the case, a microemulsion or sub-micron emulsion is not formed, by adding the so called third part, phase assembly occurs at a lower temperature than would be expected and moreover, this phase appears to assist in maintaining the microemulsion or sub-micron emulsion characteristics of the formulation during storage at normal temperatures.

For Orange Book-listed patents (shown in the main table above) generic applications must certify that the listed patents are expired, invalid, or will not be infringed by generic entry.

The non-Orange Book patents listed below do not require formal certifications, so they do not automatically impede generic entry. Instead, they represent potential opportunities for branded firms to block generic entry through patent infringment challenges.
