SAN FRANCISCO — In a matchup of two experienced Bay Area trial lawyers this week, Morrison & Foerster ultimately came out on top with a win for client Kaiser Permanente.

After a three-week trial, an Alameda County Superior Court jury sided with Arturo Gonzalez, chairman of Morrison & Foerster’s commercial litigation and trial practice group. The jury dismissed a claim filed against the health-care giant by Phaedrus Internet Development Inc. for services rendered but not paid. Gonzalez faced off against trial attorney Allen Ruby, a partner with Skadden, Arps, Slate, Meagher & Flom.
