Comcast Corp. and California accountant Conan O'Rourke, who has sued the cable-TV giant for defamation, did not reach a settlement on Wednesday, according to a Northern California court filing.

O'Rourke, who lives in San Jose, sued Comcast in late 2014 in federal court claiming that its controller, Lawrence Salva, had gotten him fired from his job at PricewaterhouseCoopers L.L.P. when O'Rourke complained about overcharges on his cable bill. U.S. Magistrate Judge Paul Singh Grewal mediated the settlement conference.

"We look forward to our day in court, but regret the circumstances that force us to spend coming years righting a wrong that Comcast could have rectified by settlement," O'Rourke's attorney, Harmeet K. Dhillon, said in a statement.

Jenni Moyer, Comcast senior director for corporate communications, said in a statement, "While we don't normally comment on pending litigation, we believe Mr. O'Rourke's claims are without merit, and we expect to be fully vindicated."
