The US International Trade Commission has rejected charges by Microsoft that Alcatel-Lucent violated some of its patents in business telephone networks.

Reuters reports that the commission dismissed Microsoft's claims on infringements of four patents pertaining to software that integrates telephones with computers for calls, messages and videoconferencing.
The administrative law judge hearing the case, Paul Luckern, had initially ruled that Alcatel-Lucent infringed one of the four patents in the initial suit. The full commission, though, said that Alcatel-Lucent did not infringe on the fourth patent either.
"The commission has determined that there is no violation of section 337," the ITC says. Section 337 refers to infringing intellectual property.
As expected, an Alcatel-Lucent spokesperson said the company was "pleased with the ITC's decision", while Microsoft expressed disappointment.
"We're disappointed that the International Trade Commission reversed Judge Luckern's ruling that Alcatel-Lucent infringed Microsoft's '439 patent. We look forward to receiving the detailed ruling so we can understand the Commission's reasoning," says spokesman David Bowermaster.
