Apple Inc. has brought on a team from Gibson, Dunn & Crutcher to help fend off dozens of lawsuits filed across the country claiming the company deliberately slowed the performance of certain older iPhone models to induce consumers to buy new ones.

The Gibson team signed on with Apple as plaintiffs in one of the cases asked a federal judge in San Jose to force the company to hold onto the batteries it’s replacing as part of a wide-scale effort to address diminished performance in older devices.
