Comtech Telecommunications Corp. Subsidiary Files Patent Infringement Lawsuit

MELVILLE, N.Y., Jun 19, 2006 (BUSINESS WIRE) -- Comtech Telecommunications Corp. (NASDAQ:CMTL) announced today that its Tempe, Arizona-based subsidiary, Comtech EF Data Corp., has filed a patent infringement lawsuit against Radyne Corporation in the U.S. District Court for the District of Arizona. Comtech EF Data Corp. asserts Radyne Corporation has willfully infringed Comtech EF Data Corp.'s U.S. Patent No. 5,666,646 entitled "Radio Frequency (RF) Converter System with Distributed Protection Switching and Method Therefor" by selling and offering for sale certain of its frequency converter products.

The patent covers a valuable RF converting system using "daisy chain" switching and eliminating the use of a centralized switching unit. In the lawsuit, Comtech EF Data Corp. seeks an injunction preventing Raydne Corporation from further misappropriating Comtech EF Data Corp.'s technology. Comtech is seeking unspecified monetary damages arising from the company's unauthorized use of the patented technology and disclosure of users of the infringing products.

Comtech EF Data Corp. had previously filed a lawsuit against another company for infringing on Patent No. 5,666,646, which resulted in that company withdrawing its product from the market.
