ADC Telecommunications said it has filed suit against PCI Technologies, alleging that certain PCI "MAXNET" modules infringe on U.S. patent No. 6,289,210 B1, which relates to "an improved RF circuit module."
ADC makes and sells those modules under the RF Worx brand, and are designed to help cable operators deliver traditional video services as well as "future targeted services" over the same network via headend signal balancing techniques.
ADC said it is seeking undisclosed past damages and injunctive relief against PCI.
PCI declined comment.
