Matthew leverages years of experience in researching, auditing, counseling, and litigating complex, multi-jurisdictional issues surrounding privacy, cybersecurity and information governance. Matthew is a Certified Information Privacy Manager and a Certified Information Privacy Professional with a specialization in United States privacy law.

Matthew focuses his practice on helping clients develop global privacy programs to meet the requirements of an incomplete patchwork of privacy and cybersecurity laws, both in the United States and abroad, including the GDPR, CCPA and its progeny, GLBA, COPPA, FCRA, TCPA, CAN-SPAM and state breach notification and cybersecurity laws. He also has extensive experience guiding clients through mergers and acquisitions to identify and mitigate privacy and cybersecurity risks. Matthew routinely advises on emerging technologies, including artificial intelligence and blockchain, and helps clients navigate self-regulatory privacy programs such as the EU-US Privacy Shield, Binding Corporate Rules, APEC CBPRs, programs covering online behavioral advertising including the DAA, EDAA, IAB and the NAI, and programs covering payment card processing. An ever-growing portion of Matthew’s practice involves helping companies prepare for privacy or security breaches and leading an immediate response in the event of an incident, successfully guiding clients through investigation, remediation, notification and ensuing government inquiries.

Matthew leans on his experience working for federal regulators to keep clients on the safe side of the watchful eye of the law. His understanding of overarching data management best practices helps him counsel beyond the letter of the law, but also facilitate worldwide expansion, interoperable business processes, and innovative uses of consumer data all while maintaining user trust. His all-encompassing, risk-based approach involves developing and executing internal and external policies for the collection, use, disclosure, sharing, retaining, transferring, and destruction of personal information. This includes managing contractual relationships with vendors, employees, acquired entities, and creditors as well as the building privacy into companies’ product development life cycle and change management strategies. Prior to joining Orrick, Matthew was an Enterprise Privacy Solutions Manager for TrustArc (formerly TRUSTe), a San Francisco-based privacy consulting and certification firm, and an adjunct law professor of Privacy Law at Santa Clara University.

Angela Colt Senior Associate Intellectual Property, Copyright, Trademark & False Advertising

New York

Angela stands at the intersection of IP law and business. She blends her legal and financial background to frame compelling legal arguments in allegations of corporate IP theft and deceptive trade practices.

Angela’s multi-dimensional approach originates from her years as a broker and investment banker. During that time, she identified the ways in which business events affect consumer confidence and corporate earnings. Now as an IP litigator, she analyzes those variables in copyright, trademark, trade secret, false advertising, and consumer class actions.

She has handled high-profile disputes including:

  • Desktop Metal, Inc. in a trade secret trial against Markforged related to 3D printing technology in federal court in Massachusetts;
  • Christie’s, Inc. in securing the dismissal of a putative nationwide class action in the U.S. District Court for the Central District of California, which declared the California Resale Royalties Act unconstitutional and preempted by the Copyright Act;
  • An international recording artist in obtaining a judgment in her favor on all counts and a dismissal with prejudice of all cross-claims in a dispute over the ownership of the rights to her music;
  • The National Football League in obtaining a dismissal with prejudice of a complaint alleging fraudulent use of the plaintiff’s identity;
  • Red Bull as a defendant in multiple putative class actions across the country challenging the nature and content of advertising statements regarding the benefits of Red Bull energy drinks;
  • Estée Lauder in obtaining dismissals of national and state consumer class actions relating to the marketing and packaging statements on cosmetic products; and
  • Hampton Creek in obtaining a dismissal of a nationwide consumer class action related to the marketing and packaging statements on Just Mayo products.

In addition to helping her corporate clients, Angela also devotes her time to various pro bono matters.

Marie-Laure Combet Partner Antitrust & Competition, Antitrust (Cartels)


Marie-Laure Combet is a partner in Orrick's Paris Antitrust & Competition Group.

Marie-Laure has been lucky to gain top-notch experience working for years alongside a former French Minister for European Affairs and former top civil servants from either French or European administrations, particularly renowned for their outstanding practice of general EU law or EU and French competition laws.

She now puts this experience at the service of Orrick's clients. The fact that she has always navigated between two legal orders (EU and French), and not only in the field of antitrust, allows her to think outside the box when it comes to finding original solutions.

Marie-Laure regularly advises on competition matters and related types of work, including compliance, advisory/transactional, and contentious matters. Over the years she has developed a significant experience in relation to State aid matters, i.e., handling very high-profile cases notably in the banking sector, the air transportation and energy sectors, as well as general EU law and regulatory matters. Additionally, Marie-Laure has deployed several compliance programs with clients and assisted them in the implementation of their behavioural commitments made to the French Competition Authority. She also assists foreign investors in relation to their reportable direct investments in strategic sectors in France or at EU level.

Prior to joining Orrick, Marie-Laure was Counsel at Clifford Chance Europe LLP in Paris. She previously worked as a lawyer with JeantetAssociés and Debevoise & Plimpton.
