Brooke advises confidential clients on the privacy and data-protection issues raised by their advertising and marketing technology — tracking technologies, data collection and sharing practices, consent mechanisms, and the gap between a company’s public privacy representations and what its technology stack actually does. She conducts tracker audits and data-mapping reviews, counsels on disclosure and consent frameworks, and represents clients in privacy-related government inquiries and enforcement matters, including a negotiated consent judgment with the Federal Trade Commission on behalf of a confidential client.

The same instinct runs through her broader litigation practice, which spans patent, copyright, and trademark infringement; trade secret misappropriation; consumer fraud; and product liability. She is currently part of a Gibson Dunn team representing a leading technology company and its founder in high-profile litigation arising out of a major open-source software ecosystem and involving antitrust and trademark claims that turn on the underlying technology. Her trial results include a $7.9 million jury verdict and a $3.6 million directed verdict against Monster, LLC on behalf of Beats Electronics in California state court; a two-week jury trial in the Central District of California for a medical device company; and a first-chair bench trial in which she obtained a permanent restraining order for a pro bono client. In patent litigation, she has won damages rulings as a matter of first impression — persuading the first court in the country to extend Federal Circuit precedent to exclude an economic model used to value a patent, reducing her client’s exposure by 80% ($335 million), and convincing a Northern District of California court, in only the second such ruling nationwide, to exclude a survey-based patent valuation, cutting exposure by $62 million.

Brooke is a frequent author and speaker on intellectual property, e-discovery, and data privacy, and a regular contributor to the firm’s client alerts in those areas.
