ROI-19-0392 Ehren Burton: Burton Color Changing Contact Lens (2019) - 6 assets

2 US patents, 1 US application, and 3 international counterparts (CN, EP, HK) related to smart contact lenses and color changing contacts. Certain of the claims disclose a contact lens with an inner layer and an outer layer wherein a sealed area exists between the two layers. The sealed area contains a liquid crystal material. In further claims, the color and structure of the liquid crystal can change based on one or more stimuli, such as temperature changes or changes in the amount of visible light. 

Four claim charts vs commercially available products are available to interested parties under NDA.
