FEBRUARY 28, 2007 -- EMCORE Corp. has filed papers seeking to extend the scope of its patent infringement action against Optium Corp. to include one additional patent and an additional product line.

FEBRUARY 28, 2007 -- EMCORE Corp. (search for EMCORE), a provider of compound semiconductor-based components and subsystems for the broadband, fiber-optic, satellite, and solar power markets, has filed papers in the United States District Court for the Western District of Pennsylvania seeking to extend the scope of its patent infringement action against Optium Corp. (search for Optium) to include one additional patent and an additional product line.

EMCORE alleges that Optium is infringing three of EMCORE's licensed patents: U.S. Patent No. 6,282,003 ("the '003 patent") entitled "Method and apparatus for optimizing SBS performance in an optical communication system using at least two phase modulation tones"; U.S. Patent No. 6,490,071 ("the '071 patent") likewise entitled "Method and apparatus for optimizing SBS performance in an optical communication system using at least two phase modulation tones"; and U.S. Patent No. 6,519,374 ("the '374 patent") entitled "Predistortion arrangement using mixers in nonlinear electro-optical applications." EMCORE believe that Optium's 1,550-nm externally modulated transmitters and 1,550-nm QAM transmitters infringe the patents.

"EMCORE continues to put considerable resources into developing unique technologies that are key to transmission of video, voice and data, and which support EMCORE's stature in the cable TV market," says Hong Q. Hou, president and chief operating officer of EMCORE. "Similarly, we will deploy considerable resources to ensure that our intellectual property is respected. We believe that Optium has infringed on several of our licensed patents and we will aggressively pursue any misuse of our intellectual property by Optium or any other companies and individuals," he concludes.
