Claim Text:
1. A method of anodizing selected portions of a housing of an electronic device, the housing including a multi-layered metal sandwich structure having an anodizable exterior laminate layer bound to a first surface of a non-anodizable layer and an anodizable interior laminate layer bound to a second surface of the non-anodizable layer, the method comprising: masking a third surface of the non-anodizable layer and a portion of the anodizable exterior laminate layer and interior laminate layer using a mask configured to prevent exposure of the third surface from a subsequent anodizing process; anodizing un-masked portions of the anodizable exterior laminate layer and interior laminate layer by exposing the multi-layered metal sandwich structure to an anodizing process; and removing the mask by cutting away the mask and the third surface of the non-anodizable layer and a portion of the anodizable exterior laminate layer and interior laminate layer.
