Heather Antoine is a Partner and Chair of the Firm’s Trademark & Brand Protection practice and Co-Chair of the Privacy & Data Security practice group.

Heather's practice is focused on protecting a company’s intellectual property; a fundamental feature of every business. Her practice includes trademark clearance and selection, domestic and foreign trademark prosecution, enforcement, proceedings before the Trademark Trial and Appeal Board (TTAB), licensing, trade secret protection, copyright, rights of publicity, domain names disputes, and counseling on brand and IP strategy. Heather believes in supporting companies at each stage – from due diligence when choosing a name, to ongoing brand management, to ensuring portfolios are safeguarded and ready for sale.

Heather is also focused on guiding businesses through the ever-expanding patchwork of privacy laws, both domestically and internationally. This includes drafting privacy policies, and guidance on how to comply with specific privacy regimes, such as the General Data Protection Regulation (GDPR), the Children’s Online Privacy and Protection Act (COPPA), and the California Consumer Privacy Act (CCPA), and California Privacy Rights Act (CPRA). Heather works with companies to design and strengthen their privacy and data security policies and practices, to help them prevent data security breaches, and to minimize the risk of a data breach.

Heather serves as Chair of the California Lawyers Association Intellectual Property Section. Heather frequently speaks and writes about IP, Internet, tech, and privacy issues. She has been quoted in publications such as the Los Angeles Times and CNBC. Heather has been recognized by her peers for excellence in her practice, having been selected by Thomson Reuters as a Southern California "Super Lawyer®" and "Rising Star®."
