OpenTV Corp. scored two winning points this week over opponent Liberate
Technologies in a longstanding patent legal battle when a U.S. District Court
judge threw out two Liberate motions.
The convoluted case -- which erupted last spring in the U.S. Court's Northern
District of California -- involves tit-for-tat patent-violation claims between
the two interactive-TV providers.

addressable multimedia presentations and streaming and management systems.
OpenTV, meanwhile, claimed that Liberate had infringed on two of its patents
covering carouseling interactive content and how content is loaded, presented,

This past week, the judge dismissed Liberate's patent-infringement claims
regarding addressable multimedia presentations. He also dismissed a Liberate
defense motion that had argued that OpenTV could not press its patent claim
because the technology was tied to industry standards work, which carried its
