California Amplifier and Competitor Trade Lawsuits

A Camarillo company and a Sunnyvale firm are suing each other, both claiming infringement on patents covering technology to encode and decode multichannel television signals.

California Amplifier in Camarillo filed suit against Pacific Monolithics, an action that was quickly followed by a counter-suit against California Amplifier by Pacific Monolithics.

California Amplifier’s lawsuit targets Pacific’s Cypherpoint system, which California Amplifier asserts infringes on its MultiCipher system. The lawsuit, filed in U.S. District Court for California’s Central District, seeks an injunction on the sale of Cypherpoint and monetary damages.
