The patent is directed to the curved lenses as well as the assembled frames and also the method of manufacturing the curved lenses.

The lenses are inserted into designer and premium-style frames that offer superior fit, comfort and a 3D viewing experience. M3D lenses also provide 100% UVA/UVB/UVC protection, allowing wearers to use Marchon3D eyewear as sunglasses.

Marchon3D president David Johnson said that this patent grant by the US Patent Office is key not only to their portfolio of intellectual property, but assures broad protection for both their existing and future innovations and products.

"The scope of protection afforded by this patent allows us to further establish ourselves as the industry leader in bringing passive 3D content to consumers," Johnson said.

The patent covers not only products manufactured or sold in the US, but also products manufactured abroad and imported into the US.

Additionally, Marchon3D has other pending applications in the US and other countries worldwide relating to different aspects of the M3D lenses.
