* U.S. Federal Circuit upholds lower court decision

* Agrees Cox did not infringe, some Verizon claims invalid
(Adds comment from Verizon, Cox)

WASHINGTON, April 16 (BestGrowthStock) – A U.S. appeals court
backed Cox Communications Inc [COXC.UL], ruling it did not
infringe Verizon Communications Inc (VZ.N: ) patents for running
an efficient telephone network.

The U.S. Court of Appeals for the Federal Circuit upheld
on Friday a lower court decision that some of the claims at
issue in the six Verizon patents were invalid and that Cox did
not infringe the rest.

In a lawsuit filed in January 2008, Verizon had accused Cox
of infringing six patents for running a telephone network by
breaking up voice signals and sending the resulting information
as “packets,” which is more efficient than maintaining a
dedicated path between the two telephones.

The U.S. District Court for the Eastern District of
Virginia had found that the portions of the patents — also
called “claims” — which were relevant to the suit were
invalid. It also found that Cox did not infringe the other

The appeals court also declined Verizon’s request to
overturn the finding that the claims were invalid.

It was not immediately clear if Verizon would appeal.

“Today’s narrow decision was based on six of our many
thousands of patents, and we will continue to promote our
innovations through patent licensing as well as monitor for
unlawful infringement,” said Verizon Deputy General Counsel
John Thorne in an email statement.

Cox Communications spokesman David Grabert noted that the
ruling was an across-the-board win for Cox. “We are very
pleased that the appeals court affirmed the jury’s decision in
all respects,” he told Reuters.

The case is Verizon Communications Inc, MCI Communications
Corp v. Cox Communications, Nos. 09-1086 and 09-1098.
