SAN FRANCISCO — Monday was not a $1 billion day in the San Jose courtroom of U.S. District Judge Lucy Koh.

For Japanese computer company Fujitsu, it was a $0 day. Unlike Apple, which walked away from trial with a record patent verdict in August, Fujitsu and the company’s lawyers at Covington & Burling weathered a total loss in a patent trial against three rivals over the wireless networking cards inserted into computers for on-the-go Internet access.
