SAN FRANCISCO — In a series of conference calls, three sets of lawyers for six defendants planned for trial against patent infringement claims by Honeywell International Inc. They divided up the witnesses, voir dire and demonstratives.

But after each call, Theodore Herhold — a Palo Alto lawyer presenting Novatek Microelectronics Corp., one of the companies accused of infringement — made other plans with his colleagues at Townsend and Townsend and Crew. They had to have another option if their co-defendants buckled, settled and left Novatek holding the bag, going to trial alone.
