Counterfeiting deterrent and security devices, systems and methods
First Claim
1. A counterfeiting deterrent device comprising:
- a plurality of layers formed by an additive process, each of the plurality of layers having a bottom surface, an opposing top surface generally parallel to the bottom surface, and at least one outer edge in an additive thickness direction that connects a periphery of the top surface to a periphery of the bottom surface,wherein each of the plurality of layers has a thickness of less than 100 microns,wherein at least one of the plurality of layers has a series of indentations formed in the at least one outer edge of the layer such that the indentations can be observed to verify that the device originated from a predetermined source.

Abstract
A counterfeiting deterrent device according to one implementation of the disclosure includes a plurality of layers formed by an additive process. Each of the layers may have a thickness of less than 100 microns. At least one of the layers has a series of indentations formed in an outer edge of the layer such that the indentations can be observed to verify that the device originated from a predetermined source. According to another implementation, a counterfeiting deterrent device includes at least one raised layer having outer edges in the shape of a logo. A light source is configured and arranged to shine a light through a slit in a substrate layer of the device and past an intermediate layer to light up the outer edge of the raised layer. The layers of the device are formed by an additive process and have a thickness of less than 100 microns each.

16. A counterfeiting deterrent device comprising:
-
at least one raised layer having outer edges in a shape of a logo; at least one substrate layer having lateral dimensions that extend beyond the outer edges of the raised layer; at least one intermediate layer disposed between the raised layer and the substrate layer and supporting the raised layer on the substrate layer, the intermediate layer having lateral dimensions that are recessed from the outer edges of the raised layer; a slit formed in the substrate layer, the slit having outer edges that correspond with the outer edges of the raised layer; and at least one light source located on an opposite side of the substrate layer from the intermediate and raised layers, the light source configured and arranged to shine a light through the slit in the substrate layer and past the intermediate layer to light up the outer edge of the raised layer, wherein the raised layer, substrate layer and intermediate layer are all formed by an additive process, and wherein each of the layers has a thickness of less than 100 microns. - View Dependent Claims (17, 18, 19, 20)
