PureSpectrum, Inc. Formally Files Patent Application for Dimmable CFL Bulb

PureSpectrum, Inc. has continued the expansion and strengthening of its intellectual property portfolio by filing a patent application with the U.S. Patent and Trademark Office for dimmable Compact Fluorescent Lamps (CFL).

In addition to filing for full patent protection for the dimmable CFL bulb design, the company has also begun proceeding to upgrade patent protection from provisional patent to patent application for a two-wire dimming device and dimmable ballast technology for linear fluorescent fixtures. Following the completion of patent filings in the U.S., PureSpectrum plans to file international patent applications pursuant to the Patent Cooperation Treaty and will also file an individual patent application in China.

PureSpectrum president and CEO Lee Vanatta said additional intellectual property protection in China has become necessary in recent weeks due to rapidly progressing licensing discussions with five U.S. lighting manufacturers with production facilities in China. The additional international patent filings, particularly in China, will provide the company and its shareholders with an extra layer of security as the company’s scope of business and revenue potential expands.

“As interest in our technologies increases on a global scale, we have accelerated our efforts to ensure that the technology is fully protected in the most relevant markets,” Vanatta said. “China has become particularly critical in the protection of our intellectual property because of the large number of lighting manufacturers with production facilities in China. We expect that PureSpectrum technologies will be integrated into products being manufactured in production facilities in China by the first quarter of 2009.”

In many countries such as Switzerland, Brazil and Canada, legislation has already been enacted which prohibits the sale and use of most forms of incandescent bulbs, and in many other countries legislation has been passed which will ban inefficient incandescent bulbs within the next few years. As the transition from incandescent to fluorescent bulbs accelerates throughout the world, technologies from companies like PureSpectrum that have engineered technologies and products to address performance issues will be in demand as consumer criticisms about the limitations of CFL bulbs become more important to manufacturers.

According to lighting industry and government energy experts, dimming is one of the most critical issues for fluorescent lighting and particularly CFL bulbs as the world prepares for the elimination of incandescent lighting during the next few years. PureSpectrum’s proprietary design for a dimmable CFL includes ballast circuitry which enables CFL bulbs to dim without interruption in linear regression the same as incandescent bulbs have dimmed for decades. Additionally, PureSpectrum’s ballast circuitry contains approximately the same number of components as a non-dimmable CFL bulb, meaning PureSpectrum technology will allow a manufacturer to sell a dependable dimmable CFL bulb for the same retail price as a non-dimmable CFL.

The company is engaged in ongoing discussions with several prospective licensing partners, which have been conducting performance tests on the dimming technology during the past three months. PureSpectrum recently commissioned additional independent testing at the request of potential licensees, and the company continues to refine the technologies based on feedback from interactions with lighting manufacturers.
