Varioptic Defends Its Liquid Lens Patent Rights

Photonics Spectra
Jun 2004
Varioptic of Lyon, France, has announced that it will enforce the patents it holds on the use of electrowetting technology to create variable-focus lenses. The determination follows Netherlands-based Royal Philips Electronics' statement in March that it plans to demonstrate fluid lenses based on that technology for high-volume manufacturing. Varioptic issued a letter to Gerard Leisterlee, chairman, president and CEO of Philips, requesting on what basis it intends to use the technology without a license or other agreement. After receiving a response, the company took legal action.
