Legal battle continues over ownership of liquid crystal display technology
Published on Wednesday, Aug 20, 2008
Beacon Journal staff report
A European patent court agrees that Kent State University and Kent Displays own the rights to a flexible liquid crystal display technology invented by professors John West and Deng-Ke Yang.
The recent decision is the latest word in a protracted international legal battle.
The patent, held by KSU and licensed by Kent Displays, was the subject of legal challenges in the U.S. District Court in Texas from 1996 until the patent was upheld in 2001.
The European Patent Office in Munich, Germany, where the patent was being challenged by several parties across Europe and the Pacific Rim, confirmed the validity of the corresponding European patent.
The patent is a key to Kent Displays' ''Reflex Display Technology,'' which enables displays that don't require any power to maintain an image and have paper-like viewing angles at all angles, including bright sunlight.
''It is gratifying to know that we were able to convey the integrity of the patent as written, in front of the European Tribunal,'' said Albert Green, chief executive officer of Kent Displays. The company was founded in 1993 to commercialize LCD technology being developed at the university.
John West, KSU's vice president for research and dean of graduate studies, says the recent win proves that Kent State's Liquid Crystal Institute leads the world in its discipline.
''With much credit to our partner Kent Displays, it is obvious that our collaborative work sets the standard in the liquid crystal field,'' he said.
