Nanoptek now has five US Patents, including Patent that was issued in May, and nine patents pending, including four international.

Nanoptek president and CEO John Guerra said US Patent No 7,992,528 directs the company’s semiconductor bandgap-shifting technology to an apparatus for hydrogen-fueled vehicles.

"US Patent No 7,995,871 directs a dynamic form of the company’s technology to an electromagnetic tuning and modulating device and process that will allow more information transfer in the increasingly crowded telecommunications bandwidth," Guerra said.

All of the patents are directed to the company’s core technology and business, which include products incorporating semiconductor photocatalysts that are nano-engineered to work more efficiently with sunlight to produce hydrogen from water.

Nanoptek is a clean-tech and renewable energy firm developing bandgap-shifted photocatalytic technology based products.
