A federal judge on Tuesday dismissed claims by communications provider Avaya that its customers’ systems were hacked into by its former contractors to gain access to proprietary software.

U.S. District Judge Joseph Irenas in Camden granted judgment to the defendants as a matter of law in Avaya v. Telecom Labs at the close of Avaya’s case, in which it had called 35 witnesses and generated more than 6,000 pages of transcripts over four months of trial.
