ADC Files Patent-Infringement Suit


ADC Telecommunications Inc. said Monday that it has filed a patent-infringement lawsuit in the United States District Court for the District of Minnesota against Switchcraft Inc.

ADC claimed that Switchcraft infringed on U.S. Patent No. 6,045,378, which relates to video jacks used in its broadcast-product line. The video jacks include features that provide improved signal transmission in high-frequency rate applications, such as digital TV and HDTV, ADC added.

The vendor added that it is seeking damages and an injunction to prevent the sale of Switchcraft's video jacks that incorporate ADC's patented design.
