Vystar Awarded Fourth US Patent for Vytex Natural Rubber Latex Material

Vystar® Corporation ("Vystar" or the "Company"), the exclusive creator of Vytex® Natural Rubber Latex (NRL), a multi-patented, all-natural raw material that contains significantly reduced levels of non-rubber particles and proteins found in natural rubber latex, today announced that the United States Patent and Trademark Office ("USPTO") issued on December 4, 2012, a fourth US patent to Vystar for its unique Vytex NRL. This most recent patent will add greatly to the Company's current intellectual property portfolio.

Vystar has previously received three (3) US patents and four (4) international patents covering various aspects of the Vytex process and its resulting composition through that process of using aluminum hydroxide with natural rubber liquid latex to remove proteins and unwanted non-rubber materials. On December 4, USPTO gave Vystar a patent on the composition of liquid natural rubber latex with an ultra low level of antigenic proteins (3.0 micrograms per gram). What is notable about this particular claim in the patent is that this ultra low antigenic protein level claim is not limited to the process of using aluminum hydroxide with the liquid latex. It is a pure composition of matter claim without dependence on the previously patented aluminum hydroxide process. This greatly expands the application of the Vytex patent protection and acknowledges that not only are the ultra low protein levels unique to the Vytex raw latex material product, but the improved optical properties and the cleaner, more translucent color, as compared to untreated field latex, are also unique to Vytex, and are now protected by this US patent.

The value to the manufacturers in using Vytex NRL in their manufacturing processes of end product is multi-faceted as a result of removing these proteins and non-rubbers and in producing a more translucent and cleaner latex. Some of these manufacturer values include cost savings by using less chemicals, water and processing to remove proteins, using less dyes and perfumes to cover up the yellow color and odor of non-Vytex natural rubber latex in the manufacturing process. The values to consumers of these end products made with Vytex NRL are also abundant. The end users enjoy the benefit of virtually no exposure to the antigenic proteins that can cause allergic reaction and irritation to natural rubber latex as well as enjoying more appealing appearances with less opaqueness, yellowing and more vibrant color when dyes are used.

William Doyle, President and CEO of Vystar® Corporation, commented, "The acceptance of these additional claims by the US patent office not only protects our IP and substantially augments our patent collection, but it solidifies our technology as superior to others in treating liquid natural rubber latex specifically. The global liquid natural rubber latex market is a multi-billion dollar market, and Vytex operates in a niche, premium sector of this market. With these new claims, we are able to show our superiority and true uniqueness, and look forward to showcasing our abilities amongst the competition."
