The Patent was granted years ago - this is old stuff I'm afraid and I'm just reminiscing in my early retirement
The Patent was owned by my University spin out company Mesophotonics which was bought out some years back by a Taiwanese company. They now own all the (basic and fundamental) photonic crystal Patents generated at the University of Southampton over a number of years.
Such is life in the world of big business and big bucks
