General counsel have to worry about a lot more than legal problems today, and the top in-house lawyers at Uber Technologies Inc., Oracle Corp. and Twitter Inc. have the experiences to prove it.

Salle Yoo of Uber, Dorian Daley of Oracle and Vijaya Gadde of Twitter described the difficulties of having to oversee legal, regulatory, policy and business matters for companies that operate in multiple countries across multiple user demographics. They spoke on a panel moderated by RPX Corp. executive vice president Mallun Yen at the 2017 Ninth Circuit Judicial Conference in San Francisco.
