Reactive Surfaces has expanded its patent portfolio in the Middle East. Israeli has granted the Austin, Texas-based company a patent for coatings having insoluble particulate materials purified from viruses and microorganisms. These particulates from renewable sources may be used as non-toxic and biodegradable bulk fillers as well as functionalized coating components. Patent protection is provided for specific coatings categories such as architectural, automotive, chemical agent resistant, aircraft and multi-pack coatings, as well as objects that are coated by these new types of biologically-derived coating materials. The claims allowed in Israel mirror similar claims in Western Europe and the Americas, and cover technical areas into which the company is expanding using genetic engineering of its bio-based additives.
