Latest Patents

One of her latest patents is titled "Process for incorporating zinc into a dyed anodized layer for protecting dye colorants from light exposure." This application relates to a method for forming an enclosure for a portable electronic device, which includes a metal substrate overlaid by an anodized layer. The method involves dyeing the anodized layer by exposing its pores to a dye and sealing the dye within the pores using a zinc-based sealing solution. The external surface of the anodized layer contains an amount of zinc between about 3 wt % to about 6 wt %.

Another significant patent is for "Colored multilayer oxide coatings." This patent describes colored oxide coatings with multiple oxide layers. The processes for forming these multilayer oxide coatings include converting a portion of a metal substrate to a primary oxide layer, coloring the primary oxide layer, and depositing a secondary oxide layer on top. Both layers can be at least partially transparent, allowing the texture of the underlying metal substrate to be visible through the multilayer oxide coating. The top surface of the secondary oxide layer can be polished to a high gloss, giving the coating an appearance of depth.
