Optigen, the Italian company that has developed a patented cold-forming process for memory-retention titanium frames, called Optigen Elastic Titanium Intelligence, has signed non-exclusive licensing agreement with Comotec of France and with Okia, a major producer and trader of eyewear components based in Hong Kong. Optigen enjoyed strong demand for its technology at MIDO, where it intervened against a counterfeiter. Eschenbach, which sees its patent for hot-formed Titanflex frames expire next July 17, has already lost two patent infringement cases against Optigen in Italy and France, and appealed against only one of them.
