Clara Duffield

Clara interprets complex legal frameworks for the benefit of her clients.


Clara DuffieldClara has deep experience in the technology and data needs of business, ranging from large companies to small startups. She has experience in a variety of key areas, including privacy, cybersecurity, data licensing, purchases and sales, intellectual property protection, start-up counseling, software licensing, equipment and hardware agreements, professional services agreements, and more.

Clara’s experience goes beyond the ability to provide basic forms and guidance. Given her background representing some of the largest corporations and financial firms in the world, she has done “deep dives” into some of the trickier aspects of technology and data law. For example, in addition to her experience with the European Union’s GDPR, she is knowledgeable about the Graham-Leach-Bliley Act (GLBA), the California Consumer Privacy Act (CCPA), the Massachusetts Standards for The Protection of Personal Information of Residents of the Commonwealth, and the New York Department of Financial Services Cybersecurity Regulation. She understands the nuances of different types of technology agreements, such as white labeling, custom hardware contracts, complex software licenses, and professional services agreements.

Beyond her technology and data experience, Clara’s general experience includes corporate structuring, privacy, intellectual property and real estate. She also has deep experience in more industry-specific legal needs, such as exchange relationships, quantitative research, white labeling, alpha capture, electronic trading, and IP licensing and management.

After graduating from The University of Chicago Law School in 2002, Clara spent eight years in private practice representing clients in complex commercial real estate, merger and acquisition, branding, and other transactional matters. Clara then worked as in-house counsel to a large financial services company, handling intellectual property, vendor contracts, technology, privacy, cybersecurity, licensing, marketing, and otherwise supporting general operations. She returned to private practice in September of 2017, and represents hedge funds, financial services companies, and technology companies in a range of transactional matters.
