Ending another chapter in a lengthy litigious battle between two competitors, Microtune Inc. said Tuesday that the U.S. International Trade Commission (ITC) has terminated an investigation brought on by Broadcom Corp.
In April, ITC Judge Sidney Harris initially determined that single-chip tuners and amplifiers imported by Microtune did not infringe on a Broadcom patent (No. 6,445,039). In a final determination announced Tuesday, the judge ruled that Microtune did not violate Section 337 of the Tariff Act of 1930.
Microtune pointed out that Broadcom still has the option to appeal the ITC determination to the U.S. Court of Appeals for the Federal Circuit.
"We will be appealing the case," Broadcom spokesman Bill Blanning said.
The ITC decision marks the latest legal victory for Microtune. Last March, a Texas Jury ruled in favor of Microtune in a separate patent infringement case brought against Broadcom.
Three other cases between Broadcom and Microtune are still pending, two of which that are patent-related. In the third, Microtune is alleging that Broadcom engaged in unfair business practices.
